I build scalable Node.js platforms, APIs, and cloud infrastructure for high-traffic products.
RomaniaWhat I'm looking for
I've delivered scalable web platforms at Netguru supporting 120,000+ monthly active users, building 70+ RESTful and GraphQL APIs that handled 800k+ daily requests. I improved service response times by 35% through microservices architecture and reduced API latency from 450ms to 250ms with Redis caching and asynchronous processing.
At EPAM Systems, I led a cross-functional team of seven developers building SaaS platforms serving 150k+ monthly active users. I designed Node.js, TypeScript, and NestJS microservices, improved backend performance by 45%, and helped raise uptime to 99.9%.
My work spans React and Next.js dashboards, PostgreSQL, MongoDB, Redis, AWS, Docker, Kubernetes, CI/CD, and automated testing. At Capgemini, I automated delivery pipelines and reduced release time by 60% while improving cloud reliability and incident response.
I enjoy leading engineering teams, shaping system architecture, mentoring developers, and delivering dependable products from backend services to production infrastructure.
