Engineered real-time multiplayer titles including Battle of Naval, Omi, and Ludo using Photon and Colyseus frameworks. Integrated custom WebSocket-based multiplayer engines to handle low-latency data transfer, room matchmaking, and synchronized multiplayer game states across concurrent player sessions.

Battle of NavalOmi

Architected the complete full-stack infrastructure by coupling a modular MVC backend with a high-performance Next.js / React frontend, establishing secure server-to-server (S2S) integration protocols and managing dynamic game catalog lifecycle pipelines. Modeled normalized relational ER schemas and indexing strategies from the ground up, enforcing strict referential integrity and data consistency across high concurrency transactional ledgers, multi-currency user wallets, and audit trails. On the backend, engineered deterministic verification routines and mathematical payout engines to validate wager cycles against race conditions, while developing modular, state-driven frontend interfaces across 5+ interactive titles (Slot Machine, Plinko, Keno, Hi-Lo) to ensure seamless,low-latency client synchronization.

Architected and deployed a high-traffic web-based promotional game suite for Coca-Cola Nepal's ICC T20 World Cup campaign, optimized for high concurrent mobile browser traffic and interactive brand engagement.

Designed the end-to-end platform architecture and relational ER schemas for a hardware-free mobile POS following the MVC pattern and Service Repository design patterns with a Next.js / React on the frontend; eliminated the need for traditional desktop terminal hardware by integrating camera-based scanning, multi-branch tracking, and optimized database queries that reduced server compute overhead by ~30%.

Designed the complete system architecture and normalized relational ER schemas for a clinical management portal using C# (.NET Core, ASP.NET Web API), Entity Framework Core (EF Core), and Next.js; implemented dependency injection pipelines and secure JWT role-based access control (RBAC) for clinical and ledger records, cutting physician administrative time by 50%–70% via organized patient histories, financial tracking, and one-click printable digital prescription generation.

Comprehensive academic and campus community portal designed for Sri Lankan undergraduates. Features centralized student networking, academic resource repository sharing, and campus-wide event collaboration toolsets.

Engineered an experimental client project integrating MetaMask wallet authentication with Web3 gameplay mechanics, connecting blockchain transaction triggers directly into web-based game loops.

Digital real estate platform specialized in land listings, property search filters, seller management dashboards, and localized interactive property mapping across Sri Lanka.

Developed the 2025 Avurudu Game suite and corporate promotional games for Sampath Bank PLC and Sri Lanka Insurance Corporation (SLIC), driving seasonal digital brand activation.
