What I'm looking for

I’m looking to own end-to-end systems for ordering/e-commerce/SaaS—shipping reliable backend and polished UIs with strong security, automated testing, and CI/CD. I thrive on modernization, performance tuning, and production support that drives continuous improvement.

I’m a Senior Full-Stack Engineer with 10 years of production experience delivering customer-owned ordering, e-commerce, and SaaS platforms across web and mobile. I take a hands-on ownership mindset, designing, building, and launching end-to-end systems under tight timelines.

On the backend, I’ve designed scalable services with C#, .NET Core, Go, and Linux-based deployment practices, packaging and operating them with Docker and Kubernetes. I’ve improved reliability, performance, and production readiness through caching, query optimization, asynchronous processing, and clearer service boundaries, while supporting troubleshooting via log and release analysis.

On the frontend and platforms side, I’ve built dynamic SPAs with Vue.js 3 and Angular 16, used Nuxt.js 3 for server-side rendering, and delivered dashboards with real-time data visualization. I strengthen delivery predictability with OWASP practices, WCAG 2.1 accessibility compliance, and automated testing (Jest, Mocha, NUnit, xUnit, Cypress, Apache JMeter), while partnering on modernization, incident investigation, and CI/CD through Azure DevOps.
