Hi, I'm Kasun — a senior software engineer with 14+ years of experience and 11,800+ hours delivered on Upwork, every contract closed with a 5-star rating. I'm unusual in that I work across five deep specialties, all at production quality: • Unity & C# game development — 7+ years across multiple production client projects, from 3D MMOs to mobile games to blockchain / NFT titles (including work on Cryptofights, an Ethereum-based fighting game) • AI Integration — production AI built into real products: a multi-tenant in-app AI assistant inside Poca Suite (DeepSeek + 32-tool agent over my Poca API, multi-tenant scope inherited via auth tokens), and Senific Capital, a multi-agent AI system analyzing the Colombo Stock Exchange (Claude + DeepSeek, 20+ agents) • Full-stack & backend engineering — Next.js, Node.js, TypeScript, PostgreSQL, MongoDB, multi-tenant SaaS architecture • Tauri 2 / Rust desktop apps — production, auto-updating, Ed25519- signed binaries released via GitHub Actions (Windows + macOS) • IoT & Raspberry Pi — hardware assembly, Python firmware, cloud sync, zero-config device provisioning Also deeply experienced with the Microsoft stack — ASP.NET, MSSQL — from years of enterprise .NET work, including the original Poca ERP (.NET + MSSQL) that I later migrated to the modern Next.js + Rust + PostgreSQL stack. Live products I own and operate through my company Senific: • Poca Suite — multi-tenant POS/ERP SaaS serving 15 production tenant databases, with built-in AI assistant (Next.js + Tauri + Node + PostgreSQL + DeepSeek) • Tuko — standalone self-hosted messaging platform (a Telegram alternative) with a full Bot API and Mini Apps framework, running in production at tuko.lk • Senific Capital — multi-agent AI research platform analyzing the Colombo Stock Exchange (Python + Claude + DeepSeek, ~10K LOC, paper-trading mode) • Cloud-synced fingerprint access device on Raspberry Pi 5 — full stack from hardware to cloud, ran in a production pilot How I work: • Full ownership — scope → design → build → QA → deploy → operate • Proactive weekly updates, no radio silence • Fluent written English, async-friendly across time zones • Modern tooling + strong engineering discipline — faster delivery without cutting corners • DevOps / sysadmin — Linux and Windows server administration, Nginx, PM2, systemd, GitHub Actions CI/CD, self-hosted infrastructure with automated backups • Comfortable leading small teams or embedding into yours Because I run my own platforms, I think like a founder-engineer — I care about uptime, observability, and shipping something that actually works in production, not just something that looks right in a demo. Need someone who can take a messy brief and return a shipped product? Send me the details — I typically reply within a few hours.
