Team Lead at Jiffy who cut Elasticsearch indexing time by 84% and built an always-on sales engine.

At Jiffy, I optimized Elasticsearch indexing to reduce indexing time by 84% and architected an always-on sales engine that runs without deployment cycles. I also engineered image enhancement pipelines that reduced claims by 57% and streamlined checkout to a 0.6% error rate.

Previously, I built and maintained Elasticsearch-based search as a Software Consultant and developed subscription and auto-extension features at GrabOnRent that increased recurring revenue. I bring 10+ years of Ruby on Rails experience, including API integrations, PostgreSQL, and production web development.
