What I'm looking for

I’m looking to build secure, highly reliable, scalable web apps in Agile teams—owning end-to-end features with strong SDLC, CI/CD automation, and QA discipline (regression + API testing) to ship production-ready work fast.

I’m a results-driven Full Stack Web Developer with a Mechanical Engineering foundation and hands-on Quality Assurance experience. I combine SDLC discipline and regression testing mindset to deliver zero-defect, production-ready features in fast-paced Agile environments.

At Konnectify, I owned critical platform modules end-to-end, including a billing page, hierarchical folders, and a connections module. I architected and deployed a white-labelled iPaaS for enterprise B2B workflows, engineered sophisticated workflow automation (catch hooks, custom code blocks, dynamic fields, and mid-workflow path insertions), and built high-throughput event logging pipelines for strong traceability.

As a self-employed Full Stack consultant, I architected 5 scalable MERN-stack web applications and improved early-stage engagement by 30% through responsive UI optimizations. I built secure, modular front-end architectures with Redux Toolkit and Context API, designed JWT-protected RESTful APIs, and automated CI/CD with GitHub Actions to reduce deployment time by 40% across Netlify and Render—backed by my QA background spanning regression and API testing.
