Tenith Hasintha
a software engineer specializing in AI systems and full-stack development, with 4+ years building scalable python backends, agentic workflows, and real-time data systems.
comfortable owning the full stack independently, shipping under pressure, and translating ambiguous product requirements into reliable, maintainable systems.
Experience
Leading the adoption of LLM integrations across multiple products and engineering real-time blockchain backends showcased at Token 2049 Singapore.
- Architected agentic AI workflows and led AI-first transition using LangChain, LangGraph, MCP, and model fine-tuning via Unsloth and Hugging Face.
- Engineered real-time NestJS backends on Bitcoin blockchain (Beatfarm & Bitcoin Graffiti) with scalable parallel UTXO indexing and Socket.IO multi-user sync.
- Mentored junior developers and led cross-functional teams with independent ownership from database architecture to production deployment.
Grew from game development into full-stack engineering, shipping production products across gaming, Web3, and browser extension domains.
- Architected Draftables a Unity American football manager game with custom MVCS architecture and Firebase integration.
- Shipped Solidity/ThirdWeb smart contract features for in-game NFT mechanics, bridging gaming with decentralized tech.
- Built the Ethos Chrome Extension a live X (Twitter) credibility-scoring tool using real-time DOM extraction and API orchestration.
Owned the full creative pipeline from 3D modeling through to high-volume NFT asset rendering, while building automation tooling.
- Built custom Python/Blender scripts for batch procedural NFT generation and automated After Effects compositing.
- Managed complete art pipeline: 3D modeling, texturing, and final rendering for NFT collections.
Key Projects

About Me
beyond shipping production systems, i'm driven by the intersection of hardware and software from configuring raspberry pi servers to building robotic arms with inverse kinematics. i believe the best engineers understand systems at every layer.
whether it's fine-tuning llms with unsloth, engineering real-time blockchain backends, or wiring up esp32 biometric devices i'm most alive when building things that push boundaries and solve real problems.
