Our Story

Lumatriq is two senior engineers. Serhii Ruban designs backends and AI layers, with fintech payments and billing experience. Kostiantyn Makarovskiy has ten years in software and owns scope, acceptance criteria and release. No account managers, juniors or subcontractors: the people who scope your project write the code. Models handle boilerplate, CRUD, tests and types. We write auth, payments and data integrity ourselves. Fixed price, fixed scope, senior only.

What Sets Us Apart

Two senior engineers, no middlemen

The two founders scope, build and release every project. No account managers, no juniors, no subcontractors. Models handle boilerplate, CRUD, tests and types; we write auth, payments and data integrity code ourselves and review everything the models generate.

Fixed price, fixed scope

Every project starts with Diagnose: $750, five working days, credited to the build. You get a process map, written scope and architecture notes, and keep them even if you stop there. The build is quoted once and the price changes only if the scope does.

Built to run, not just to demo

Systems launch with retries, alerts and a cost cap on every AI call. MVPs ship with CI/CD, tests and migrations. WordPress sites ship with a performance budget: our own sites score 100/100 on Lighthouse.

Commonly Asked Questions

Four steps. 1) Fit check: free, you send a brief and get a reply within 48 hours. 2) Diagnose: $750, five working days. We map how your work and data move, decide what stays in no-code tools, what moves to code and what gets cut, and write the scope. The fee is credited to the build, and you keep the process map, scope and architecture notes even if you stop here. 3) Build: fixed price per written scope; it changes only if the scope does. 4) Grow: optional retainer, $3K/month for 20 senior hours, pausable anytime.

Three kinds. AI workflows: connecting AI tools, CRMs, billing and APIs into workflows with queues, retries, alerts and a cost cap on every AI call ($3K to $10K). SaaS MVPs: multi-tenant Node.js MVPs with a landing page, shipped in weeks ($8K to $15K), plus fix-or-rebuild audits of apps built with Lovable, Replit or Bolt. WordPress engineering: custom WordPress and WooCommerce builds and Core Web Vitals rescues (landing pages from $2.5K, full builds from $5K). We also do white-label engineering for agencies and studios.

You talk to the two engineers who build your project, nobody in between. Kostiantyn owns scope, process maps, acceptance criteria and release; Serhii owns the backend and AI layer. Progress is reported against the written scope, and results are reported in numbers: failed steps alerted, AI spend against its cap, LCP in milliseconds, PageSpeed score. If something can't be measured, we say so.

Both. We keep n8n, Make or Zapier where they are enough, and move a workflow to custom Node.js when it needs retries, deduplication, audit trails or higher volume. We also fix automations someone else built: Diagnose maps what breaks and ends with a fix list and a fixed price.
