👋 Hello!
I'm Oleksii Mielnikov,
AI Full Stack Engineer
I'm a software engineer with 10+ years in production web development, now working where the model meets the product. At EPAM I build and operate agent-based tooling for the software delivery lifecycle and instrument it with telemetry on cost, tokens and latency. I ship with React, Next.js, TypeScript and Node.js, and run WorldVote — my own product on Claude API and Supabase. Preparing for the Anthropic Claude Certified Architect — Foundations exam (November 2026).
Building the AI-native web, front to back.

Software Engineer — AI Native Engineering
EPAM Systems- Build and operate LLM-driven automation for the software delivery lifecycle — agent-based tooling that takes a task from specification through implementation to a reviewable change, with quality gates at each step
- Design prompts, agent instructions and skill definitions as maintainable engineering artifacts: versioned, reviewed and measured, not one-off text
- Instrument AI workflows with telemetry on cost, token usage and latency, and use it to drive down the price and duration of each run
- Onboard colleagues onto AI tooling: run breakdowns of real sessions, write internal materials, and feed failure modes back to the teams that own the platform
- Continue delivering production frontend: React and AEM interfaces, full WCAG accessibility remediation, and complete RTL support for Arabic and other right-to-left languages
- Selected for EPAM's AI Native Engineering program and its internal GenAI certification track (Anthropic → AWS → Google Cloud)
