Rahul Tank

I’m a Senior Software Engineer with 5+ years delivering production web platform applications across healthcare, supply chain, and automotive domains. I ship features end-to-end—from architecture to deployment—with 90%+ test coverage and near-zero production regressions, while staying comfortable owning client communication and mentoring engineers.

Recently at Eluminous Technologies, I enhanced a production web automation platform with a 2-member team and improved CAPTCHA solve rate to 95%+ across 100+ concurrent requests by iteratively optimizing an integrated ML pipeline. I also contributed to a multi-module dental clinic SaaS dashboard—built reusable React components and integrated Twilio and Firebase—cutting average feature delivery time by 40%.

Across the RSPO-compliant palm oil supply chain platform, I drove frontend stability by increasing test coverage to 90% and reducing client-reported bugs from 4–5 per sprint to near-zero within 2–3 sprints. I collaborate directly with stakeholders to translate ambiguous requirements into detailed specs before development, eliminating mid-sprint rework across multiple release cycles.

Previously at The Gateway Group, I worked full-stack on a cross-platform vehicle aftersales platform serving 150+ organizational users, including being the sole mobile engineer building React Native and developing Node/Express REST APIs over PostgreSQL for technician workflows. I integrated camera and push notifications (FCM), extended Microsoft Active Directory authentication, managed App Store/Google Play deployments, and led TDD adoption—mentoring 3 junior engineers and reducing code duplication from 40% to under 5% while maintaining green SonarQube quality gates.

Now I’m focused on end-to-end Generative-AI products, including hand-rolled SSE token streaming and RAG over pgvector with Zod-validated structured LLM output. In projects like DocChat, I built a grounded RAG assistant with strict grounding prompts and citation extraction to achieve a 0% hallucination rate on out-of-scope queries.
