Hi, I'm Chandan ๐Ÿ™

I build at the seams between apps, networks, and AI. Swift and networking are my home turf; lately I've been building local-model systems, financial document pipelines, and tools that make a homelab feel like useful infrastructure.

I'm an Engineering Manager at Paytm Payments Bank, leading Web, Android, iOS, and internal UI engineering across five teams. Before that, I spent ~15 years shipping mobile and full-stack software, including consumer-facing work on Paytm and J.P. Morgan Markets/Execute. I still like getting close to the code, especially when a problem crosses system boundaries.

What I'm working on

  • AIResume (private) โ€” A portfolio you can question, powered by local models and a custom RAG pipeline with repeatable retrieval evaluations. Try it live.
  • TxParse (private) โ€” Turns messy bank PDFs and transaction emails into a reconciled ledger; balance checks and PostgreSQL row-level security keep the data trustworthy and isolated. See the live site.
  • Mac SSH Manager โ€” A macOS menu-bar app that opens SSH access for a timed window and closes it automatically. Supports LAN and Tailscale.
  • dev-tools โ€” A browser workbench for developer utilities, notes, and a whiteboard, with a strict CSP and SSRF-safe URL expansion behind the scenes Try it live.
  • WhatsApp Gateway (private) โ€” A containerized messaging API with QR pairing, an operator dashboard, revocable keys, and an outbound history.
  • Statix โ€” Native agents and a central dashboard keep an eye on the CPU, memory, disks, and networks across my homelab.
  • lan-devices โ€” A SwiftUI dashboard for finding LAN machines, checking SSH reachability, and launching terminal or remote-control actions.
  • LGLogger โ€” An iOS logging package that puts filtered, persistent logs and export controls inside the app itself.
  • FTP Server Dashboard (private) โ€” A small LAN file-sharing service with one access mode across FTP and web, host-only administration, and idle shutdown.

Things you can actually use

dev-tools JSON, cURL, regex, notes, and a canvas whiteboard in one self-hosted workbench.
statix Monitor multiple macOS and Linux hosts from one dashboard.
Mac SSH Manager Timed SSH access from the macOS menu bar
lan-devices Discover LAN machines, watch SSH reachability, and open a terminal.
LGLogger Inspect and export iOS app logs without attaching a development cable.
