At Fourth Rev Edu, I led the phased migration of a legacy Java monolith to microservices, defining service boundaries with Domain-Driven Design. The move enabled independent, zero-downtime releases and cut feature development time.
I built a Gemini API grading pipeline that scores student answers against rubrics using structured prompts, parsed output, and BullMQ background jobs with automatic retries. It cut manual grading time by an estimated 60%.
I also automated releases with GitHub Actions, reducing deployment time by over 85%, and deployed backend services on AWS. My work has included Redis caching, Docker deployments, and rebuilding SMS and WhatsApp campaign delivery with batch processing and retries.
