I work with modern technologies and frameworks to build scalable, performant applications. Here's my comprehensive technology ecosystem with core and specialized skills highlighted.
With over 5 years of experience as a Full Stack Developer, I've had the opportunity to work across both engineering and design roles—building scalable backend systems and crafting intuitive user interfaces.
My day-to-day involves translating complex product requirements into robust features, collaborating closely with cross-functional teams, and continuously improving user experience through thoughtful design and efficient code. This hybrid perspective allows me to bridge the gap between design and development—rapidly prototyping ideas, offering pragmatic design input, and delivering production-ready solutions. I take pride in building products that are not only functional but also elegant and user-friendly.
Focused on delivering features that drive real business value and improve user experience. I prioritize understanding product goals and translating them into scalable technical solutions that directly impact growth, retention, and revenue metrics.
Key Achievements: Reduced debugging time by 60%, improved user engagement by 40%, and delivered features that directly contributed to 25% revenue growth.
Reduced debugging time by 60% through full-stack OpenTelemetry tracing across microservices. Designed and deployed FastAPI + GraphQL APIs handling 10M+ requests/day with sub-200ms response times via strategic Redis caching and PostgreSQL optimization. Proven expertise in Kubernetes, Docker, Helm, AWS, and CI/CD pipelines with GitHub Actions for seamless and secure production deployments. Integrated Debezium, Airflow, and WebSockets for real-time, event-driven architectures and data pipelines.
