What I'm looking for

I seek a senior engineering role where I can lead migrations and cloud deployments, improve delivery through CI/CD, mentor teams, and work with distributed stakeholders in a collaborative, growth‑oriented environment.

I am a Senior Full Stack Developer with over six years driving migrations, modernizations, and full‑cycle web application development for enterprise clients. I deliver scalable solutions across healthcare, e‑commerce, and US government sectors, focusing on reliability and performance.

I specialize in .NET Core, C#, JavaScript, SQL, and Azure DevOps, and I build CI/CD pipelines that have improved delivery speed by up to 50% while reducing deployment failures. I have led migrations of legacy systems to modern stacks and maintained near‑perfect uptime during major releases.

My work includes improving data performance (up to ~90% faster CRUD on large datasets), implementing automated testing frameworks that reduced regression bugs, and creating reusable component libraries to accelerate parallel development. I also emphasize clear English communication with distributed teams and stakeholder alignment.

I am results‑driven and documentation‑oriented, creating tutorials and technical docs that cut support tickets and increase client satisfaction, contributing to repeated contract renewals and measurable team velocity improvements.
