Profile

About Me

I'm a Senior Full Stack Engineer with 6+ years of experience building enterprise-scale applications and cloud-native solutions. My expertise spans modern frontend frameworks (React, Next.js) and backend technologies (Node.js, Express), with deep proficiency in AWS services and serverless architecture.

Throughout my career, I've led development initiatives at companies like SERV (SaaS/CRM platform) and Legal & General Investment Management, working on projects that served millions of users. I specialize in designing scalable systems, implementing complex features, and mentoring junior developers.

I'm passionate about writing clean, maintainable code and staying at the forefront of technology. When I'm not coding, you'll find me exploring new technologies, contributing to open-source, or sharing knowledge with the developer community.
