What I'm looking for

I seek senior full-stack or technical lead roles where I can design scalable architectures, mentor teams, drive CI/CD/cloud adoption, and build reliable, user-focused systems.

I am a Senior Full Stack Engineer with extensive experience building and maintaining web and cloud-native applications using C#, .NET Core, Node.js, TypeScript, and modern front-end frameworks. I have led teams to deliver production systems across banking, government, insurance, and SaaS domains, designing clean architectures, integrating third-party services, and improving reliability and performance.

I have driven CI/CD, cloud deployments (AWS, Azure, GCP, DigitalOcean), and automation while writing unit tests and reducing downtime through proactive maintenance. My achievements include leading full-stack teams on large integrations, implementing data synchronization to CRMs, and developing mission-critical systems for financial and government clients.
