01 (Intro)
How I work, and who I have built for
Products should be intuitive, reliable, and built to last. As a senior full-stack engineer, I use human-centred design and modern AI-assisted engineering to ship work people actually want to use.
I help you build your dream product, fast, without trading away security, quality, or maintainability. From architecture to production, I own the stack so delivery stays sharp and the codebase stays clean.
My goal is to turn an idea into a product that is not only efficient, but enjoyable to use and easy to evolve. Great engineering should feel invisible, and make the product feel inevitable.

How the work is run, in four movements
1
The contract, before the component
The data model, the API shape and the failure cases are agreed before a single screen is drawn. Most projects fail in the gaps nobody named at the start.
2
Small slices, behind tests
Work ships continuously behind automated tests and CI. You see the product grow week by week — there is no reveal at the end, and therefore no surprise.
3
Short loops with the owner
You speak directly to the person writing the code. No account manager, no relay, no fortnight’s delay between a question and a decision.
4
No surprises at launch
Security review, performance budget and handover documentation are finished before go-live, not promised after it. The business owns everything on day one.
(Why one senior owner)
What a practice of one is actually worth to you
01
Fewer handoffs
One person holds the interface, the API, the database and the infrastructure. Nothing is lost between three teams and a project manager, because there are none.
02
Weeks, not quarters
Decisions happen in hours. A change you ask for on Monday is usually in staging by Wednesday — not scheduled into a sprint that begins a fortnight from now.
03
Cheap to change in year three
The codebase is written to be inherited: documented, tested and conventional. Whoever you hire next will thank you, and they will not ask to rewrite it.

Straight answers on availability, time zones, stack and track record. The full profile has the experience timeline, skills and education.
Full profile & experience Who is Rushan Edirisuriya?
Rushan Edirisuriya is a senior full-stack software engineer based in Colombo, Sri Lanka, with 8+ years building production web platforms in React, Next.js, TypeScript and Node.js. He specialises in fintech and digital payments, and has delivered for companies in Australia (Attractor Solutions, Melbourne) and the United States (Paywat, Pennsylvania).
Is he open to full-time roles or contract work?
Both. Rushan is open to full-time remote roles as a senior or lead full-stack, frontend or backend engineer, and to contract engagements, from fixed-scope product builds to retained engineering support from three months. Current availability: Open for Q4 2026.
Can a company in Australia, Singapore or elsewhere in APAC hire him remotely from Sri Lanka?
Yes. He works remotely from Colombo on UTC+5:30, which shares most of the Singapore and South-East Asian working day and the Australian afternoon, and he already works across Australian, United States, UAE and European hours. You deal directly with the engineer doing the work, and he replies within one business day.
What is his core tech stack?
React, Next.js and TypeScript on the front end; Node.js, NestJS and Express with PostgreSQL, MySQL, MongoDB, Redis, Prisma and TypeORM on the back end; AWS (ECS, Lambda, S3, CloudFront), Google Cloud Run, Docker, Terraform and GitHub Actions for cloud and CI/CD; and Jest, Cypress and Playwright for testing.
What fintech and payments experience does he have?
At Paywat he lifted payment success by 15% through gateway and retry optimisation on a platform processing 100K+ transactions a month at 99.9% availability. At Attractor Solutions he built the claims, eligibility and payment workflows of the Norton cashback platform, multi-region from one codebase. Earlier he built a Hyperledger Fabric rewards platform integrated with the Supreme Crypx exchange.
How does he work with remote product teams?
The data model, API shape and failure cases are agreed before a screen is drawn. Work then ships in small slices behind automated tests and CI, with short loops directly with the product owner, and security review, a performance budget and handover documentation are finished before go-live.
Where did he study?
He holds a BSc (Hons) in Information Technology, specialising in Software Engineering, from the Sri Lanka Institute of Information Technology (SLIIT), and made the Dean's List in 2018.
How can I contact him?
Email rushan.edirisuriya@gmail.com, connect on LinkedIn, or use the enquiry form on this site. He replies within one business day.
