About

I’m Sergei Tabanar, an API & integration developer and automation-focused software engineer building integrations that connect business operations, payments, and customer records. I enjoy turning real-world workflows into reliable services—designing REST APIs, webhooks, authentication (JWT/bearer, HMAC), scheduled sync jobs, and idempotent processing so systems stay consistent even when data arrives late or changes.

I’ve delivered integrations across tournament platforms, multi-tenant SaaS workflows, offline-to-cloud synchronization, and video-processing services. When I work, I own requirements through implementation, testing, deployment, and troubleshooting, and I’m comfortable spanning backend/data (Python, FastAPI, PostgreSQL, Supabase) through frontend delivery (React/Next.js) and quality automation (Selenium/Playwright).
