Andrii T.

Senior full-stack engineer. I ship AI-powered SaaS, integration workflows, and data products from spec to production. Most of my work falls into four buckets: - AI-powered SaaS MVPs. Next.js + Supabase/Postgres + OpenAI/Anthropic. From "we have a Notion doc and a wireframe" to a logged-in product in 2 to 4 weeks. RLS, auth, billing, the boring parts done right. - Workflow and integration glue. n8n / Make / Zapier wired into HubSpot, Airtable, Stripe, Twilio, Google Workspace, and custom REST APIs. Lead triage, document standardization, sync pipelines, billing automations. - AI features dropped into existing products. Chat assistants, RAG over your docs, transcribe audio, structured extraction, background agents. I plug into your codebase, not next to it. - Scrapers and data pipelines that don't break weekly. Playwright / Puppeteer + clean storage, retries, alerting. Price tracking, catalog aggregation, market data, lead lists. - Stack I reach for: TypeScript, Next.js, Node, React, Python, FastAPI, Postgres, Supabase, OpenAI, Anthropic, LangChain, n8n, Make, Zapier, Airtable, Stripe, Twilio, Playwright, Cloudflare. Simpler tools when simpler tools win. How I work: - I write the brief back to you before I start. If we can't agree on the success criteria, we don't start. - The smallest demo-able slice ships in days, not weeks. We layer from there. - Direct communication, async-friendly. The person you hire is the person writing the code. No agency, no sub-contracting, no handoffs. - Senior-level codebase: typed end to end, tests where they matter, a README a new dev can follow on day one. Best fit when: - You have a real spec, or at least a clear "build this with these tools," not "make us something beautiful." - You want to ship something usable now and iterate, not staff a 6-month committee. Pixel-perfect Figma fidelity is not the deliverable. The working product is. - You want the project done, not the team built. - If that sounds like your project, send the brief. I usually reply the same day.
