What began as simple curiosity has become a kind of responsibility I take seriously: to build well, and to build for more than myself.
Over the past few years I have helped build a monetary protocol platform from the ground up, owning the full stack from smart contracts and blockchain infrastructure to backend services, frontends, and the AI and agentic systems that tie it all together. Most of what I know I learned the hard way: by building real systems, breaking them, and rebuilding them better.

Goodness ExchangeFull-Time
Lead Protocol EngineerJun 2026 - PresentSri Lanka
- Transitioned from the founding engagement into a permanent Lead Protocol Engineer role, owning the engineering direction of the Protocol through its public launch and beyond.
- Continue to own and build the full engineering stack hands-on: the Hyperledger Besu Diamond smart contracts, 22 TypeScript microservices, 5 Next.js frontends, and a multi-continent K3s platform.
- Driving the Protocol from beta to production: hardening the remaining launch gates, expanding the validator set toward mainnet, and shipping the modules still on the roadmap.
- Continuing to set the Protocol's architecture and technical decisions under a spec-first, decision-logged engineering process.
Full-Stack Software EngineerJan 2025 - May 2026Sri Lanka
- Architected and delivered a blockchain fintech platform from the ground up: 1.26M lines of source code across 9 repositories and 11,264 commits, spanning smart contracts, backend, frontends, and global infrastructure.
- Built the platform's core financial subsystems: identity and KYC, token issuance and supply economics, treasury and reserve management with multi-signature approvals, payments, lending, escrow, dispute resolution, and partner and institutional accounts.
- Built the blockchain layer across two stacks: 7 Hyperledger Fabric Go chaincodes (identity, tokenomics, governance, lending, organizations, tax, admin), then led the March 2026 migration to a Hyperledger Besu EIP-2535 Diamond of 20 Solidity facets and 14 storage libraries (13,557 lines), verified by a 758-test parity suite under QBFT consensus.
- Built and modularized 22 TypeScript microservices on Clean Architecture and CQRS with a transactional outbox, guaranteeing zero data loss on blockchain writes and improving read performance 70x to 2,000 req/s.
- Decomposed a 43,936-line monolith into 6 domain-driven bounded contexts using the strangler fig pattern (shadow mode, dual-write, gradual cutover) with zero downtime.
- Architected 5 Next.js 16 applications (participant wallet, command center, institutional and partner admin, public marketing site) in strict TypeScript with Zod validation and a backend-for-frontend proxy that keeps JWTs out of the browser.
- Engineered the data and infrastructure layer: a 3-replica high-availability PostgreSQL cluster (PgBouncer pooling, 150+ tables, 470+ indexes) with Redis Sentinel failover, on a 4-node K3s cluster across 3 continents at zero added cost, with zero-trust networking and an authored Prometheus, Grafana, and Loki observability stack (63 panels, 15 alert rules).
- Led security hardening that cut platform CVSS risk exposure by 60%: tiered rate limiting, default deny-all network isolation, multi-layer RBAC, and live incident response.
- Designed and ran a hierarchical multi-agent AI development system on Claude Code (18 agents, 33 reusable skills, 10 enforcement rules) that cut per-module delivery time roughly 55% across 48+ measured sessions.
- Rebuilt biometric KYC liveness detection from a 60%-success ML model to an on-device MediaPipe pipeline with deterministic 8-frame scoring, cutting false positives from 15% to under 0.5%.
