About Lumias

Your technical partnersin the trenches.

A technical strategist and a full-stack engineer who got tired of watching good business ideas get destroyed by agency bloat and over-engineered stacks.

The team

Two founders. No layers.

  • Rita Larina

    CEO / Technical Strategist

    Rita turns a vague idea into a scope, a budget and a test plan. She reviews third-party builds while the warranty is still active, and she is usually the one asking the question that changes the plan.

  • Valery Zuevich

    CTO / Full-Stack Engineer

    Valery builds and runs the systems: Kotlin services, React and TypeScript frontends, and the infrastructure underneath them. He also ships CalcuCare, which keeps the studio honest about maintenance.

Who we are

We build and operate our own software daily.

Lumias is run by two IT professionals: a technical project manager and a full-stack engineer. We did not start a studio to sell hours. We started it because we kept watching founders pay for software that nobody wanted.

We do not only take client money and write code. We build and operate our own product, CalcuCare, which means we face the same trade-off decisions every single day: what to cut, what to ship, what to run in production for years.

We translate technical trade-offs, keep your burn low, and explain the "why" until you feel completely in control of your own product.

Think of us as your co-founders for hire.

How we operate

Four rules we do not bend.

  • We build for the real world

    Software is only useful if real people pay for it or use it to save time. We put our energy into tools that solve messy, unsexy operational problems.

  • Direct co-founder communication

    You work directly with us, not with a mid-level account manager passing messages to a junior dev team. We act as a genuine extension of your core team.

  • Zero tech jargon

    We tell you what a project actually costs, how long it will take and where the risks are. If we do not know something, we tell you upfront, not after billing forty hours to find out.

  • Execution over hype

    We do not pretend to be a fifty-person agency with a fancy office. What you see is what you get: two pragmatic operators who value clean execution over polished pitch decks.

What we stand for

Connection, authenticity, passion.

  • Connection

    Real dialogue with users, real trust within the team, real relationships that shape the product.

  • Authenticity

    We question norms, speak plainly, and reject the idea that tools must be cold and faceless.

  • Passion

    We build because we care. When it is hard, we return to that care.

Let's build the smallest thing that proves people will pay for it.
