All of this was client work under NDA, so it's written up as case studies instead of live links.
TV Streaming Platform
Full-Stack Developer · Contractor (SM Code)
- Problem
- Three separate applications sharing the same platform needed consistent, reliable APIs while staying stable in production across multiple environments.

- Reliable releases and measurable improvements to platform performance and long-term stability.
ERP for Amazon Sellers
Full-Stack Developer · Norte DOO
- Problem
- Sellers needed one place to monitor Amazon performance and compare prices against eBay, Walmart, and Ingram without juggling multiple tools.
- What I Built
- Built dedicated applications, searches, and widgets for market analysis, price optimization, and competitor research on top of real-time data feeds.
- Result
- Sellers gained a scalable, data-driven view of their business that supported faster pricing and sourcing decisions.
POS System on Raspberry Pi
Full-Stack Developer · Hardworking Technology
- Problem
- Running a point-of-sale system on constrained embedded hardware while keeping it as reliable as a traditional POS terminal.
- What I Built

- Result
- A dependable POS system running reliably in production on low-cost hardware.
Car Dealership Management App
Full-Stack Developer · Hardworking Technology
- Problem
- Dealership operations involved multiple interconnected business rules that needed a single, coherent system.
