About Abhishek
Most software in regulated spaces is just pretty UI layered over fragile spreadsheets. I build production systems that encode actual banking norms, credit policy algorithms, and legal workflows into deterministic, privacy-first software. From commercial credit appraisal engines to cross-platform mobile apps, I take heavy domain logic all the way to production, on mobile and web.
