Building websites, online stores, and the systems behind them.

Sigmatic builds company websites, e-commerce platforms, and web applications, with Car Passion Events and NEVINI among the portfolio examples. The work also includes AI automation, internal tools, dashboards, and integrations that connect business systems.

Alongside that work, Sigmatic builds Stakingverse, operates Sigmacore RPC, and supports EVM teams. Jordy remains involved in the LUKSO ecosystem through Foundation work, developers, validators, and partnerships.

02·Flagship- LUKSO + Ethereum liquid staking

Stakingverse is the flagship product.

Stakingverse is Sigmatic's liquid staking product layer. It leads LYX staking on LUKSO, with sLYX as the liquid staking token, and extends into Ethereum staking through integrations using StakeWise V3 infrastructure.

Sigmatic works across product direction, staking UX, infrastructure operations, validator and node maintenance, DeFi mechanics, and the technical translation layer between protocols and users.

  1. 01$14M peak TVL on Stakingverse.
  2. 02LUKSO staking through stakingverse.io and app.stakingverse.io.
  3. 03ETH staking integration using StakeWise V3 infrastructure.
  4. 04White-glove node, server, validator, and maintenance services for clients.

03·Services

Development, operations, automation.

Sigmatic is a technical studio for businesses and teams that need working websites, e-commerce platforms, infrastructure, and automation.

01

Website & E-commerce Development

Web development

Sigmatic designs and builds fast, reliable company websites and e-commerce platforms. Depending on the project, that can be a fully custom website in Next.js and TypeScript, a Shopify store, or focused improvements to an existing site. The work covers information architecture, responsive design, frontend development, product catalogue and checkout journeys, integrations, technical SEO, performance, accessibility, and deployment. Every project is founder-led from first idea to launch. If you need a website or online store built, redesigned, or improved, get in touch to discuss the scope.

02

Blockchain & DeFi Development

EVM systems

Sigmatic builds the on-chain and backend systems EVM teams ship to production: smart contracts, staking flows, protocol integrations, and the backend APIs that hold them together. The work spans Uniswap V3-style infrastructure and cross-chain mechanics, including the routing, liquidity, and EVM bridge UX behind cross-chain DeFi protocol work kept intentionally private for confidential clients. It also covers the liquid staking contracts and flows behind Stakingverse, with sLYX on LUKSO and an Ethereum integration on StakeWise V3 infrastructure, plus the UUPS-upgradeable on-chain registry behind Universal Trust. Engagements run founder-led and direct: technical execution, close work on product direction, and ownership from contract through backend to the point where users actually transact.

Node, Validator & RPC Operations

Infra operations

Sigmatic runs the infrastructure blockchain teams depend on once launch is behind them: validator operations, node maintenance, and DevOps, plus paid archive-node RPC access and partner LSP indexing delivered through Sigmacore for teams building on LUKSO. Onboarding for archive RPC and indexer access is contact-based, so setup matches what a team actually needs instead of a fixed plan. For clients who want operations handled end to end, Sigmatic provides white-glove node, server, validator, and maintenance services. It is grounded in real operating history: Ethereum proof-of-stake testing and node operations since 2020, and ongoing developer and validator support through work with the LUKSO Foundation. The point is reliable chain data and validators that stay alive under production load.

AI Automation & Agent Systems

Practical AI

Sigmatic builds AI tools around specific business workflows: website chatbots, data extraction, reports, internal dashboards, and integrations between the tools a team already uses. The work can include AI agents, bots, and LLM tooling, with review steps and permissions scoped to the task. For blockchain teams, this extends to on-chain agents with identity and reputation, including Universal Trust and LUKSOAgent. Each engagement starts with the process that needs improving and a clear scope for the tool and its handover.

05·Stack

Builder and operator, at the same time.

Sigmatic combines product design, frontend and backend development, and infrastructure operations. The work connects what people see on a website or in an app with the data, integrations, and systems behind it.

That can mean a custom Next.js website, a Shopify store, a business dashboard, or an AI workflow. For blockchain projects, the same approach extends to Universal Profiles, liquid staking, RPC services, validator operations, and DeFi integrations.

06·AI

AI automation for everyday business workflows and blockchain teams.

Sigmatic builds website chatbots, data extraction tools, internal dashboards, and AI workflows that connect the systems a business already uses. Each project starts with a specific task, from answering recurring questions to preparing reports or processing information.

The blockchain side includes on-chain agent workflows and projects such as Universal Trust and LUKSOAgent, where identity, reputation, and permissions are part of the system. Agent tools such as OpenClaw are chosen to fit the workflow.

07·Background

Foundation, founder, infra. In that order.

  1. 2017

    Started in blockchain before the institutional brochure era

    Started exploring blockchain in 2017, learning the culture, wallets, and early on-chain products before the space became packaged for institutions.

  2. 2020

    Moved into Ethereum infrastructure and early PoS testing

    Started running nodes, testing early Ethereum proof-of-stake networks, and troubleshooting validator and dev infrastructure during the Ethereum 2.0 testnet era.

  3. 2022

    ETHCC Paris hackathon work

    Award-winning hackathon execution in Ethereum contexts, long before AI agents became a fashionable slide title.

  4. Aug 2024

    Working for the LUKSO Foundation

    Started as tech community manager for devs and validators, moved into partnerships and growth, now all-round across ecosystem and developer work where needed.

08·Recommendations

What people Jordy has worked with say.

From colleagues, managers, and founders who worked with Jordy directly. Originally published on LinkedIn and reproduced here verbatim.

I worked with Jordy through the Foundation for the New Creative Economies (FNCE) and the LUKSO Community.

He's one of the most dedicated, hard-working, and ambitious contributors that we had. He cares, looks at details, and pushes where he thinks things are missing. He is an absolute asset for the community and the project at large. People like him are what make projects move and hold people accountable within.

I can highly recommend Jordy for any project anywhere and I hope we keep him along in the LUKSO community

I have known Jordy for a long time. Our relationship began with technical collaboration, which later evolved into a strong business partnership. Our company has never been let down by him; his involvement has directly driven our growth and significantly enhanced our technological capabilities.

Jordy excels in IT sectors such as Web3 and AI, demonstrating a unique ability to combine both technologies and maximise their potential. We constantly exchange knowledge. Jordy’s potential is virtually limitless – ranging from writing code and managing platforms to leading Web3 and AI project communities, and conducting international C-level business negotiations. We highly value our relationship and the opportunity to collaborate in such rapidly developing sectors.

Jordy is a rare individual who combines high conviction with real execution.

A lot of people can spot problems. Fewer can turn those problems into products, workflows, partnerships, and momentum. Jordy does that consistently. He has an unusually strong work ethic, teaches himself whatever the moment requires, and then applies it in a way that creates leverage for the people around him.

What stands out most is his ownership. If something important is missing, Jordy does not wait for perfect instructions or institutional permission. He figures it out, builds, tests, improves, and keeps going until there is something useful on the table. That showed up clearly in his work around our organization's AI transformation initiatives, where he was early to see the practical value, went deep independently, and then helped others inside and outside the team improve their own workflows.

He also brings a level of honesty that strong teams need. Jordy says what he believes is true, even when it is inconvenient, but he does it because he cares about the project and the community. Earlier on, that intensity could sometimes arrive faster than the room was ready for. What impressed me is that he worked on that. He turned directness into a sharper leadership tool: still candid, still demanding, but more effective at creating alignment across the team.

Jordy has earned respect from builders, community members, partners, and team members because he is not performative. He's been extremely helpful to the team, putting the work first, holds himself and others to a high standard, and has the technical and interpersonal range to move between product, ecosystem, partnerships, and execution.

I would bet on Jordy in any environment that values ownership, speed, integrity, and people who make things happen.

Jordy and I have started and worked on quite a few projects together, and I must say, he's one of the most capable and driven people I've had the chance to build with.

Together we designed and shipped infrastructure that demands real rigor around security, reliability, and on-chain mechanics; built out community-facing platforms; and had hands-on involvement in helping launch a blockchain. Across all of it, Jordy's real strength was his judgment and his ability to break genuinely hard problems down and drive them to completion.

He is one of the hardest-working and most dedicated people I know. Whatever a project demanded, Jordy stepped into the role it needed and led from there... and the pace and quality of what he delivered never stopped impressing me. That combination of grit and clarity is exactly what makes him a great leader. To this day he remains one of my closest confidants, and I always look forward to whatever we'll build next.

I give Jordy my highest recommendation. Anyone who gets the chance to work with him will quickly see they're dealing with a true professional and a sincere colleague.

I had the pleasure of working with Jordy at FNCE for almost two years. Throughout our collaboration, I consistently appreciated his professionalism, technical expertise, and strong commitment to both the project and the wider community.

Jordy combines deep technical knowledge with a solution oriented mindset and a strong attention to detail. He performs exceptionally well under pressure, remains focused on achieving results, and is always willing to support his colleagues. His ability to understand complex strategies and translate them into practical solutions has been a significant asset to our team.

Beyond his technical skills, Jordy is an outstanding team player. He brings empathy, collaboration, and a positive attitude to every interaction, making him someone that everyone enjoys working with. His contributions have had a lasting impact on our project, and he has become a key figure within the team and community.

I highly recommend Jordy to any organization looking for a dedicated, knowledgeable, and collaborative professional.

I had the pleasure of managing Jordy, and he is genuinely one of the most productive and dependable people I’ve worked with.

Jordy combines exceptional organisation and proactivity with a real passion for the work he does. Whatever task or project was put in front of him, he approached it with energy, ownership, and an extremely high standard of execution. Beyond being highly capable, he’s also a fantastic person to work with — collaborative, positive, and someone who builds strong relationships both internally and externally.

Over time, Jordy became one of our go-to people whenever we needed to move quickly and implement something effectively. He developed an impressive ability to use AI agents to rapidly build and improve dashboards, websites, internal tools, and business-critical applications. What stood out most was not just the speed, but the quality and reliability of the output. His productivity reached an exceptional level, even compared to an already incredibly strong baseline.

Any team would be lucky to have Jordy. He brings the rare combination of operational excellence, adaptability, technical fluency, and strong business instincts. I would confidently recommend him to any organisation looking for someone who can execute at a high level, drive growth initiatives, and consistently deliver results.
