Products I run, healthcare backends I ship at work, and the open-source tools in between.
Running in public today. Visit them, use them.
Developer utilities that never leave your browser.
19 client-side tools: an API client with cURL import, JWT signing and decoding, hashing, password and NanoID generation, timestamp and cron helpers, JSON to TypeScript, regex tester. No backend, no tracking, installs as a PWA and works offline.
A speed test in your browser toolbar.
Browser extension that measures download, upload, ping, jitter and packet loss against Cloudflare's edge, rates readiness for calls, streaming and gaming, keeps a local history and exports a PDF report. Ships with a self-hostable Express server.
Every electricity bill in Tamil Nadu, one screen.
Tracks TNEB bills for many meters at once without logging in to the portal. Reads the portal's captcha in-process with Sharp and Tesseract in under a second, and keeps the meter list encrypted in the browser with AES-GCM. Tamil and English.
A curated shopping storefront, run from the edge.
Mobile-first affiliate storefront with search, budget filters and short links for social posts, plus a private admin for the catalogue. Redirects return at once and log clicks in the background; outbound fetches are guarded against SSRF.
Engineering notes from real production bugs.
The writing site: incident-style write-ups of bugs, their root causes and the verified fix. Static Astro with full-text search, a full-content RSS feed and dual-theme code highlighting.
Healthcare SaaS systems. The code is internal, so there is nothing to link.
Replaced a paid form vendor with an in-house platform.
Co-designed and shipped the in-house Form Builder that replaced a third-party subscription: dynamic schema validation, presigned S3 uploads, reporting endpoints, and EMR workflows driven by Amazon SQS.
Business-hours-aware fax routing with retries.
Automated fax routing and forwarding that respects business hours, retries on failure and applies per-tenant rules, built on RingCentral APIs, SQS, SES and scheduled jobs.
Patient-list pipeline cut from 26s to 19s.
Reworked reporting queries during the MongoDB to DocumentDB migration: compound ESR indexes instead of collection scans, and paginated batches instead of runaway pipelines that ran out of memory.
Small, sharp utilities and learning material, all on GitHub.
Claude Desktop on Fedora, verified.
One shell script that installs and updates Anthropic's Claude Desktop beta on Fedora from the official Debian package, checks the signing key and checksums, and sets up the Cowork VM.
A clipboard manager that pastes for you on COSMIC.
Rust panel applet for System76's COSMIC desktop. Keeps text and image history, pins entries across reboots, and pastes the chosen entry straight into the window you were in.
Which pincodes can this Amazon product ship to?
Playwright tool that checks an Amazon.in product's delivery status across a list of Indian pincodes and writes CSV or JSON with screenshots. Reuses a saved session to avoid repeated captchas.
