Experience
Where I have Been Employed and What I Have Done
As part of the development team for Edulog Athena, I contribute to building and optimizing scalable software that helps school districts streamline bus routing, trip planning, and fleet management. My work spans debugging complex issues, developing new modules like Field Trip Management, improving admin dashboards, and ensuring smooth integration between routing algorithms, mapping systems, and parent/driver-facing portals. I collaborate across backend services, cloud infrastructure, and frontend interfaces to deliver efficient, reliable, and user-friendly solutions. My contributions directly support district operations by improving efficiency, safety, and communication for students, drivers, and parents.
At TestFiesta, I work as a full-stack engineer focused on platform reliability, performance optimization, and resolving complex issues across a highly asynchronous, distributed system. I debug problems across the full stack—frontend rendering, Node.js backend logic, PostgreSQL queries, worker execution flows, and service-to-service communication. My responsibilities include designing safe database migrations, improving query performance through indexing and refactoring, and tracing UX issues from UI interactions down to backend and data models. I collaborate closely with QA and UI/UX teams to reproduce edge cases, analyze GitHub issues, and deliver high-quality fixes. Within my first month, I resolved over 50 complex issues, significantly strengthening system stability, scalability, and overall product performance.

I’ve been leading Fully Booked as a solo Full Stack Developer since day one, building everything from the ground up. I architected and developed the entire platform, including cross-platform mobile apps for minibus operators (using React Native with Expo), an admin dashboard (React.js), a customer enquiry website, and a JavaScript widget that integrates booking functionality into any external site. The backend was built with NestJS and MongoDB, all deployed using Docker on DigitalOcean.
As a Top Rated Plus freelancer on Upwork, I’ve collaborated with global clients to deliver full-stack solutions across mobile, web, and desktop platforms. I’ve handled everything from initial product ideation to deployment and scaling, often working directly with founders on early-stage startups.
