About

Results-driven Senior Software Engineer and Team Lead with 8+ years of experience architecting and developing high-performance, scalable applications. I'm passionate about pushing the boundaries of what's possible with code, and I'm always eager to explore the latest tech trends (especially anything AI-related – trying to work myself out of a job, one algorithm at a time! 😂). Proven ability to lead teams, deliver complex projects, and optimize systems for maximum efficiency. Expertise in full-stack development using the MERN stack, Java Spring Boot, and modern cloud technologies (AWS, Google Cloud). I believe in the power of technology to transform the world, and I'm excited to be a part of that journey.
