SUMMARY
Full-Stack Developer ·
Lead Developer · Full-stack developer (Python/FastAPI, React/TypeScript) with 2+ years of commercial
AI-assisted experience, now Lead Developer of a small team of 3 developers. I build a crypto futures
development trading platform: a distributed system of 10+ microservices covering market-data
streaming, strategy simulation and live portfolio execution. I deliver production code with
AI agents (Claude Code, Cursor) as a core part of the workflow, using them for design,
implementation, debugging, review and testing, with strict architecture, lint and testing
rules around them.

WORK EXPERIENCE

2026 Crypto futures trading platform (real-time data, simulation, live trading).
As Lead Developer (team of 3 developers):
Lead architecture decisions, task breakdown, code review and delivery for the platform.
CONTACTS Set engineering standards: layered architecture rules, mandatory lint, format and type
[open contact info](look above in the "contact info" section) checks in CI, targeted testing.
Introduced AI-assisted workflows (Claude Code, Cursor, specialised review and test
[open contact info](look above in the "contact info" section) agents) as a team practice.

Odessa, Ukraine
read market bars directly from PostgreSQL in read-only mode to keep the pipeline
consistent.
TECH SKILLS Built the React/TypeScript frontend for real-time trading: live prices, order-book data,
analytics dashboards. It is responsive and mobile-first, on a shared design system.
