Learn how I built a production-ready image management application using Next.js 16, AWS S3, TypeScript, and presigned URLs. Instead of routing uploads through the application server, the app uses direct browser-to-S3 uploads with an automatic server-side fallback, secure validation, pagination, and a responsive image gallery.
For a technical assessment, I built a Counter-Strike 2 demo analyzer in TypeScript using @laihoe/demoparser2. The tool parses CS2 demo files, analyzes player deaths, calculates a surprise score based on player orientation and mouse movement, and generates ranked results for further AI analysis.
Motherland CRM Solutions is a full-stack, multi-tenant SaaS Customer Relationship Management platform I designed and built from the ground up. It helps sales teams move away from chaotic spreadsheets and into a real-time, role-based CRM system where admins can import leads, assign them to agents, and track every interaction as it happens. This project evolved from a simple “Excel import tool” into a production-ready platform with real-time synchronization, strict data isolation, role-based access control, and a scalable API architecture. This post focuses on the engineering decisions behind the system and not just what I built, but why it was built this way.
