What I'm looking for

I’m looking for a team where I can own end-to-end delivery—shipping secure, high-performance React/ASP.NET Core products, optimizing Azure CI/CD and infrastructure, and collaborating cross-functionally to reduce load times and accelerate measurable outcomes.

I’m a Full Stack Engineer with 6+ years of experience building scalable web applications that reduce load times, streamline workflows, and support thousands of users. I drive end-to-end development—engineering React/TypeScript UIs, ASP.NET Core APIs, and secure authentication—while optimizing performance and reliability across the stack.

In my recent roles, I’ve delivered measurable business impact: an enterprise ESG platform that improved compliance reporting efficiency by 40% and adoption by 35+ clients, alongside a 35% reduction in average load time and scaling to 1000+ concurrent users. I also integrate AI/ML insights to cut manual analysis by 50 hours/month, manage Azure CI/CD pipelines and Docker, and coordinate cross-functional teams to ship features with zero critical defects.
