I build software that businesses actually run on.

The problem

Small Indian businesses need invoices that are actually GST-compliant — correct CGST/SGST/IGST breakdowns, HSN/SAC codes, amounts in words — and most global tools get this wrong or overcharge for it.

What I built

A complete invoicing platform: a SwiftUI iOS app with a minimalist design system, backed by a Go (Gin) + PostgreSQL API deployed on Azure Container Apps under a custom domain.

Highlights

• GST-correct PDF engine. Multi-page invoice PDFs with full GST breakdowns, HSN/SAC codes, and Indian-Rupee amount-in-words — built in Go, no third-party PDF service.
• Email delivery. SendGrid integration sends invoices straight to the client's inbox, sharing one PDF pipeline between download and email paths.
• Production operations. Docker Buildx images, Azure CLI release workflow, environment separation between TestFlight and production, and real incident debugging.

The problem

A local clinic needed to be found on Google by patients searching for hearing care, load fast on budget Android phones, and publish health articles without a developer.

What I built

A Next.js 16 site styled entirely with Tailwind CSS v4 utilities, with dynamic article routes, comprehensive on-page SEO, and Google Analytics to measure what actually brings patients in.

Highlights

• SEO as architecture. Semantic markup, per-page metadata, and dynamic routes built for long-tail health search queries — not bolted on afterwards.
• Performance on real devices. Optimized images and utility-only styling keep the site fast on the low-end phones most patients actually use.
• Delivered to a real client. Scoped, built, deployed, and handed over — including the communication and revision cycles real client work demands.

The problem

Roll-call attendance wastes lecture time and is trivially gamed by proxies. Presentsz verifies physical presence instead: an ESP32 BLE beacon in the classroom, detected by the student's phone.

What I built

A React Native (Expo) app that scans for the room's BLE beacon and checks the student in, backed by a Go (Gin) + PostgreSQL API managing classes, sessions, and attendance records.

Highlights

• Embedded to backend. Custom-flashed ESP32 beacons broadcasting unique room IDs, consumed by mobile BLE APIs and persisted through a relational backend — one system, three domains.
• Honest status. App and API are functional; end-to-end BLE testing on physical devices is in progress. It's here because it shows range, not because it's finished.
