What I'm looking for

I am looking for a role that offers opportunities for growth, collaboration, and innovation in a dynamic team environment.

I am a Senior Full-Stack Developer with over 12 years of experience in architecting and delivering scalable, cloud-native applications and microservices. My expertise lies in leading the full software development lifecycle (SDLC) in Agile environments, where I have consistently engineered high-impact solutions that prioritize scalability, code quality, and maintainability.

Throughout my career, I have successfully led the end-to-end delivery of complex projects, such as a HIPAA-compliant MVP for a healthcare startup and an AI-powered portfolio simulator that significantly increased user engagement. I thrive in fast-paced, cross-functional teams and have a proven track record of mentoring junior engineers and collaborating with stakeholders to translate business requirements into technical solutions.
