In Development
Process

From brief to deployed

01
01 — Discovery
Understand the problem
We deep-dive into your business, users, and goals before writing a single line. No assumptions — just absolute clarity on what needs to be built and why.
02
02 — Architecture
Design before building
Tech stack, data model, API design, infrastructure — we engineer the system properly upfront so there are no costly surprises halfway through.
03
03 — Build & Ship
Iterative delivery
Continuous development with regular checkpoints. You see real progress at every stage — not just a big reveal at the end that misses the mark.
04
04 — Scale & Support
Long-term partnership
We don't disappear after launch. We monitor, optimise continuously, and help your product evolve as your user base grows.
About

Built by an engineer,

Founder & Lead Engineer
Email Portfolio ↗

I'm Dineth Wijesooriya, a software engineer from Sri Lanka. I founded ByteArrays to take on meaningful engineering challenges — building software that is both technically excellent and genuinely useful to the people who use it.

I work with clients across Sri Lanka and remotely worldwide, from startups finding product-market fit to established businesses modernising their tech stack. Whether it's an AI-powered educational platform, a real-time enterprise system, or a mobile product from scratch — every project gets the same level of craft and commitment.

My approach is simple: understand deeply, architect properly, build with care, and ship with confidence. That's the ByteArrays standard — non-negotiable on every project.
