I’m a Senior Full Stack Software Engineer with 8+ years of experience building scalable web applications, REST APIs, backend systems, data validation engines, and cloud-based platforms for remote and distributed teams. I bring hands-on expertise in TypeScript/JavaScript, Node.js, Python, React.js/Next.js, and production-minded engineering practices.

In recent roles, I built FastAPI endpoints for insurance claim validation, created Chrome Extension user workflows, and set up Playwright end-to-end testing integrated into CI/CD to reduce release risk. I also led backend rule-engine work using Python, FastAPI, Pydantic, SQLAlchemy, and Alembic with clean API design.

At Think-it, I scaled CSV data validation from fewer than 20 rows to 40,000+ rows using asynchronous chunk-based processing, improved architecture with Redis, and delivered robust unit tests. I developed scalable REST APIs and dashboards, upgraded Directus, automated role-based permission migrations across staging and production, and used complex PostgreSQL (CTEs, window functions, raw SQL) with PostGIS to improve endpoint performance—while mentoring a junior engineer and managing stakeholder expectations.

Across other engagements, I delivered full-stack platforms with AWS DevOps automation (Elastic Beanstalk, Lambda, EventBridge, cron/job automation), built analytics dashboards with Metabase and Google Analytics, and improved frontend consistency through design systems. I also developed data processing workflows (including Excel VBA automation) and supported global, EU/US-facing product delivery through technical leadership and remote collaboration.
