About
I’m a Full Stack Developer with 5+ years of experience building scalable, innovative solutions across media, healthcare technology, communications, and SaaS platforms. My expertise covers JavaScript/TypeScript (React, Angular, Node.js, Next.js), Python (Django, FastAPI), and Go (Gin, Fiber). I specialize in microservices and robust APIs, with hands-on experience in event-driven systems using Kafka. I work extensively with databases such as PostgreSQL and MongoDB, using Prisma ORM for clean and efficient data access. On the infrastructure side, I design and deploy containerized solutions with Docker and Kubernetes, manage cloud environments (AWS, GCP), and use Terraform for Infrastructure as Code. Redis helps me ensure high performance and scalability across distributed systems. I bring together intuitive frontends and high-performance backends to solve real business challenges with clean, maintainable code. Along the way, I’ve worked closely with cross-functional teams to turn requirements into reliable, future-proof software solutions. Passionate about clean code, testing, and database optimization, I thrive in agile environments where collaboration and innovation drive meaningful impact. 🚀 Always excited to connect and talk about technology, innovation, and building great products!
