What I'm looking for

I seek a collaborative engineering role where I can lead technical efforts, mentor developers, build scalable full-stack solutions, and work closely with clients on impactful projects.

I am a dedicated software engineer with strong expertise in clean architecture, full-stack web development, and delivering scalable, maintainable solutions. I lead teams, guide junior developers, and act as a primary client contact to ensure alignment on requirements and deliverables.

At Alliance Software Inc., I have been appointed project and technical lead roles, contributing to design, task estimation, code reviews, test implementation, and internal tooling that optimized team workflows. I have built web interfaces for ATM cardless transactions and created REST API simulators for testing.

I work across frontend and backend stacks—React/Next/TypeScript on the front end and Node.js, Express, ASP.NET Core, and PHP on the back end—while emphasizing code quality, mentoring, and effective client communication.
