Daria C.

Full-stack engineer with 5+ years building production web applications - React, Next.js, TypeScript, Node.js, PostgreSQL. I've delivered SaaS products end-to-end and led frontend teams. Most recently I built and shipped an entire streaming platform solo: frontend, backend, database architecture, Stripe subscriptions, third-party integrations, hosting, and CI/CD. Before that I spent 2.5 years as frontend tech lead on a healthcare platform, taking it from an unstable prototype to a live product used by real clients - four user roles, real-time chat, video calls, complex permission systems. What I do: 1. Build SaaS platforms and dashboards from scratch or improve existing ones 2. Own the full stack when needed - APIs, database design, auth, deployment 3. Integrate third-party services: Stripe, payment systems, streaming, video, email automation 4. Architect reusable component systems and scalable frontend structure 5. Set up CI/CD pipelines, staging environments, and release workflows Stack: React · Next.js · TypeScript · Node.js · PostgreSQL · Supabase · GraphQL/REST · Tailwind · MUI · Zustand/Redux · Docker · AWS · GitHub Actions · Stripe · WebSockets How I work: I read before I write - in existing codebases I follow the patterns that are already there rather than imposing my own. I raise problems early instead of working around them silently, give realistic estimates, and validate my work in staging before it reaches you. If something in the plan is a bad idea, I'll say so before building it. Open to both long-term partnerships and well-scoped project work.
