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 worked across the full stack of a monetary protocol platform: smart contracts and blockchain infrastructure, 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.

Work Experience
Goodness ExchangeFull-Time
Founding Software EngineerJun 2026 - PresentSri Lanka
- Accountable for how my own work is verified and how delivery is reported across the protocol's backend, data, contracts and wallet, building with AI coding agents (Agentic Workflows) under independent verification.
- Verification: a read-and-run verifier role with no edit rights, fail-closed pre-push gates with per-file ratchets, and acceptance checks re-run against the running system.
- Delivery: container releases and database migrations on development Kubernetes environments from pinned commits, plus database change-control and access practices.
- Planning: delivery programmes built from a measured dependency graph, with readiness gates defined as commands that can pass or fail, and engineering decisions recorded in a spec-first, decision-logged process.
Full-Stack Software EngineerJan 2025 - May 2026Sri Lanka
- Full-stack engineer on a private, blockchain-based financial protocol, across the participant wallet, layered backend services, data and smart contracts, learning each layer from its documentation and applying it as the protocol grew.
- Frontend Applications: worked on the protocol's wallet and other frontend apps in Next.js and strict TypeScript, later rebuilding the wallet in place on a design system, test-first with explicit error states. Backend-for-frontend layers keep service tokens off the browser.
- Backend Systems: built TypeScript microservices on Clean Architecture and CQRS, with a transactional outbox so a database change and its ledger command are recorded atomically. Planned the extraction of a fast-growing subdomain into its own service after adversarial review.
- Infrastructure & Data: PostgreSQL with Prisma, migrations replayed from an empty database, connection pooling, backup and restore, and K3s development environments with monitoring.
- Security: money and security paths built to fail closed, with typed errors, tiered rate limiting and role-based access.
- Identity & KYC: worked on participant onboarding: on-device capture with liveness checks and reviewer workflows for human decisions.
- Blockchain & Smart Contracts: Go chaincode on Hyperledger Fabric, then extended an existing prototype into a larger suite of upgradeable EIP-2535 Diamond contracts on an EVM chain, with upgrades checked on-chain.
- Engineering System: planned and supervised parallel AI coding agents on Claude Code in non-overlapping scopes, re-running type-check, lint and tests before accepting output. Built a local pre-push pipeline that mirrors CI and led test-suite integrity work.
