Services

What I take
off your plate.

One engineer across the whole stack — or plugged into your team exactly where the extra hands are needed.

(01)

Web Applications

SPAs, SaaS products, dashboards & e-commerce with React + TypeScript. Fast, accessible, production-ready.

 (02)

Mobile Apps

Cross-platform iOS & Android with React Native — one codebase, shipped to both stores.

 (03)

Backend & APIs

Node.js services, REST & GraphQL APIs, database design and integrations that scale with you.

 (04)

AI Agents & Automation

LLM-powered agents, chatbots, RAG pipelines and workflow automation — with reliable guardrails, not demos.

Stack

Boring where it should be,
modern where it pays off.

Comfortable joining codebases with existing conventions — Mantine, Tailwind, tRPC, NestJS, you name it.

Process

How a project runs.

You see progress every week and own everything from day one — repos, infra, docs.

Scope & estimate

Your idea becomes a clear scope, milestones and a fixed estimate — before any code is written.

Build in sprints

Weekly sprints with clean commits, code review and a staging build you can click through.

Demo & refine

Live demos every week. Feedback goes into the next sprint — no surprise reveals at the end.

Ship & hand over

Production deploy, documentation, full handover of repos and infrastructure. It's your code.

Engagement

Ways to work
together.

Pick the model that fits — switch later if the project changes shape.

Fixed scope

Project-based

Best for MVPs, landing pages and well-defined builds.

  • Clear milestones & deliverables
  • Fixed price, fixed timeline
  • Invoice per milestone

Retainer

Dedicated hours

Best for ongoing products that keep evolving.

  • Reserved weekly capacity
  • Direct Slack / Teams line
  • Prioritized backlog

Team extension

Embed with your team

Best for agencies & startups needing senior hands.

  • Your repo, your workflow
  • Standups in your timezone
  • Code reviews & mentoring
