Products

What we build when the customer is us.

Every claim on this site is backed by something in here. These are not case studies written after the fact — they are products we designed, built, shipped and still operate, with our own money on the line.

Lyka

An open hybrid operating layer that gives every workload a deliberate home across owned hardware and public cloud, without changing how developers ship.

Explore Lyka

The problem it exists for

Dev environments, preview builds, CI runners and model inference are steady, predictable load. Renting all of it by the hour meant our own iteration speed was being priced rather than engineered — and that is before data residency rules push a workload somewhere specific.

The usual answer is to pick a side: all public cloud and accept the bill, or run your own metal and accept a worse developer experience. Lyka exists because that trade should not be necessary.

What it does

  • Places each workload across owned hardware, AWS, Azure or GCP based on policy, cost, latency and data path.
  • Keeps one developer experience regardless of placement — moving a workload is an operations decision, not a rewrite.
  • Runs a private inference layer with bounded context and concurrency scheduled against real GPU memory.
  • Holds identity together across the estate with OIDC and RBAC that stay coherent as clusters multiply.
  • Promotes artifacts through environments so what passed in staging is what reaches production.

Why it matters to you

Fimyd runs on it in production. When we talk about cloud cost, hybrid placement or private AI in an engagement, we are describing something we operate daily rather than something we read about.

Fimyd

Shop from trusted local sellers near you. Paste a link, photograph a product or scan a barcode, then compare real offers from sellers who actually have it.

Visit Fimyd

The problem it exists for

Local sellers hold real stock and cannot be found online. Buyers search a national marketplace, wait for delivery, and never learn the shop two streets away had it today. The gap is not supply — it is discovery.

Closing it means resolving a product from whatever a person happens to have: a link, a photo, a barcode. That turns a shopping app into a matching problem.

What it does

  • Resolves a product from a pasted link, an uploaded image or a scanned barcode.
  • Ranks real offers from nearby sellers against price, distance and trust.
  • Onboards sellers and gives them catalogue and inventory tooling they will actually use.
  • Runs matching and retrieval in the request path, where latency is a product decision rather than a benchmark.

Why it matters to you

Fimyd is the reason Lyka exists. It is also the proof that we can take a consumer product with real transactional weight from nothing to production — and keep it running while building the infrastructure underneath it.

Earlier platforms

Where the primitives came from.

Two platforms built in 2024. We are not selling them today, and we are not going to dress them up as current products. They belong here because the engineering they forced is the engineering we now do for other people.

2024 · Institutional SaaS

LastClass

A campus platform covering attendance, groups, library, notes and alumni networking — one deployment serving many institutions that must never see each other's data.

Forced: multi-tenant identity, role hierarchies, per-institution data isolation
Status · built 2024, no longer in active development
2024 · Two-sided platform

LenV

Photography end to end — booking photographers, renting gear, portfolios and client hubs, with a heavy media pipeline carrying all of it.

Forced: two-sided booking state, transactional integrity, media at volume
Status · built 2024, no longer in active development
Why there are no client logos here

A logo wall proves someone paid you. This proves we can build.

Most engineering firms ask you to trust a list of clients whose systems you will never see. We would rather hand you the software and let you form your own view.

Open Lyka and read the architecture. Open Fimyd and try to find something near you. If the work does not hold up, no case study we wrote about it would have either.

That is what we build when the customer is us. What we build for other teams is on the Solutions page.
