Worked on KDK's Income Tax, GST and TDS products, mostly fixing bugs in the Go services, React frontends and the desktop connector.
- Fixed filing, import/export, reconciliation and portal-sync bugs across the ExpressIT, GST, TDS and connector codebases, and added ITR-6 JSON import for AY 2026–27.
- Brought a customer-matching step down from 534 MB to 55 MB of memory, and cut one client's lower-deduction certificate checks from 4,519 rows to 9.
- Built an internal LLM Management page where the team can edit and validate the prompt configs used by the tax backends. Configs are saved to S3 and the related ECS service gets reloaded.
- Wrote a Claude Code /bugfix command that we added to 12 repos. It takes a Zoho issue through reproduce, fix, test and PR using Zoho MCPs, Claude in Chrome and the GitHub CLI, and stops for approval before anything external.
