Software Developer & Proprietor · Crystal Software
I build backend systems and cloud infrastructure that hold up under real load. Specializing in scalable architecture, server operations, and business automation — from Java APIs to production email servers.
Technical Stack
Backend systems, cloud infrastructure, and the glue that connects them — built to stay running.
Backend & Languages
Cloud & Infrastructure
Tools & Services
Work & Projects
Real problems solved in production — from business software to infrastructure that doesn't need babysitting.
Proprietor & Lead Developer
Run Crystal Software end-to-end — setting technical direction, designing accounting solutions for SMBs, and building the web infrastructure those products run on. Every architecture decision lands on my desk, and so does every deployment.
Amazon → Tally Sales Automation
Built a Spring Boot middleware service that pulls live sales data from the Amazon SP-API and syncs it directly into Tally, replacing a daily manual export-import cycle. Cut reconciliation time for clients from hours to minutes, with zero data entry.
Production Email & Cloud Infrastructure
Configured and deployed self-hosted email servers using Mailcow on Ubuntu, running across Contabo VPS and AWS EC2 instances. Handled full DNS setup — SPF, DKIM, DMARC — SSL termination, and aaPanel environments. Zero downtime since go-live.
