PlayPickup • Freelance

Feb 2022 - Apr 2024 • 2 yrs 2 mos

As Lead Developer, I architected a high-concurrency social sports ecosystem from scratch using .NET 8 and Angular. My focus was on bridging physical sports with digital networking through real-time data and AI. System Architecture: Engineered a scalable backend using .NET Core with Clean Architecture and CQRS patterns. Developed a hybrid data layer using EF Core for complex relations and Dapper for high-performance, low-latency read operations in MySQL (utilizing optimized Stored Procedures). Real Time Engagement: Integrated Socket.IO and SignalR to power 1-on-1 chats, group lobbies, and live match data transfers, supporting thousands of concurrent connections. AI Integration (Gemini & Claude): * Leveraged Google Gemini for intelligent matchmaking, analyzing player skill/behavior to suggest optimal team balancing. Integrated Claude 3.5 for context-aware community moderation and sentiment analysis in group chats. Automated match recaps using Generative AI to create shareable social media content. Global Logic: Built a custom Time Management Engine to handle seamless match scheduling across global time zones (UTC to Local synchronization). DevOps & Automation: * Setup Nginx reverse proxy, SSL, and domain hosting on custom servers. Orchestrated complex Cron Jobs for automated notifications via AWS SES/SNS and background data injection. Established CI/CD pipelines via GitHub Actions for automated testing and deployment. Impact: Delivered a 40% improvement in API response times and a 65% increase in user engagement through AI driven features. Tech Stack: Asp.NET 8, Angular 17, MySQL, Dapper, Redis, AWS (SES/SNS/EC2), Socket.io, Gemini/Claude APIs, Nginx, Docker.
