I'm Sheshan Bandara, a senior full-stack engineer with 5+ years building and scaling production web platforms for SaaS, EdTech, and FinTech teams. If you want to hire a full-stack developer who owns a feature from architecture through deployment, and not just the comfortable bit in the middle, that's the work I do every day.
I work end to end across React and Next.js, Node.js, TypeScript, PostgreSQL and Supabase, and AWS, with the DevOps and testing discipline to keep what I ship running in production. Available for consulting, contract, and scoped product builds, remotely with EU and US-East overlap.
I design for the system you'll need in 18 months, not just the demo you need on Friday. Module boundaries, data contracts, and tenant isolation come before UI polish.
Every feature lands with auth, error states, observability, and tests. CI is the floor, not the ceiling, and rollbacks stay refreshingly boring.
Frontend, backend, database, and infrastructure, plus the unglamorous middle of backups, migrations, RBAC, and audit logs
EdTech - Microservices - Video
The legacy LVMS was difficult to scale and maintain. The UI/UX was outdated, playback was inconsistent, analytics and logs became unreliable under heavy data, and several workflows caused data inconsistency issues. Video uploads also took hours or overnight before lectures were ready to stream.
FinTech - Hardware - Realtime
Community finance groups needed a more reliable way to manage members, loans, payments, and identity checks. Paper ledgers made balances difficult to verify, while member identity at the counter depended on manual recognition.
SaaS - Multi-tenant - Bilingual
A multi-branch institution needed one governed system for branch operations, finance workflows, alms scheduling, donor pledges, and data that had previously lived across logbooks. And a better way to guide visitors and share temple/place information without relying on printed boards or manual explanations.
For consulting and project work I usually start with a short discovery to scope the problem, then quote fixed-scope or a weekly/hourly rate. Send the context and I'll suggest the engagement model that fits, no mystery invoices.
Both. I take select consulting and contract engagements, and I'm open to full-time senior roles where I can own meaningful product and platform outcomes.
I'm based in Colombo, Sri Lanka (UTC+5:30) and work well with EU mornings and US-East overlap, async by default with live calls when decisions need them.
Send a short note with the context and I'll reply with how I can help.
