Three systems, still in production.
Government tax administration, consumer lending, and the site you are reading. Each row is the outcome; the case study behind it has the problem, the approach and the architecture.
- 01Tax & CAMA - CatalisA single platform now used across all 50 states, helping local governments manage millions in annual tax revenue with more efficiency, accuracy, and transparency.
- 02MeridianLink PortalA smoother, more automated end-to-end application experience aimed squarely at reducing drop-off across the funnel.
- 03Personal PortfolioA production site — this one — spanning 8+ routes, a 30+ utility tools hub, and a full case-study framework applied to every project including itself, with interactive systems (sound, tilt, custom cursor, scroll-linked animation) tuned for restraint over gimmick. Shipped and iterated on continuously since mid-July 2026.
Five years, four teams.
Property tax for US counties, loan origination for American credit unions, and agency work before both. Pick a company to read what the job actually was.

What people say.
Talks about AI systems the way an engineer should — retrieval quality, failure modes, and tests first, hype never. The kind of person you want reviewing the layer your product depends on.
Karthik Hebbar M N — Senior Software Engineer 2, AI Growth, SmartQ Understood the automation problem in business terms, not just technical ones, and came back with something that actually moved the numbers. Delivery was quick and the follow-through was better.
Dr. Ajay Kumar — Founder, AI Automation Labs Takes ownership end to end — you hand over a problem, not a task list, and it comes back done with the edge cases already handled. Easy to plan a sprint around.
