Software engineer in Sri Lanka

I'm a 23-year-old Full-Stack Cross-Platform Software & AI Engineer from Colombo, Sri Lanka, with 5+ years of experience shipping production web, mobile, and desktop applications. I currently serve as Team Lead & Director of IT Development at BBDSP Consultant, where I lead a cross-functional team of 16+ developers across web, mobile, and AI projects.

End-to-end product development: web applications, mobile apps, cross-platform desktop tools, AI chatbots and automation, SEO-optimised landing pages, full-stack POS systems, and IT consulting. I handle everything from architecture and UX to deployment, CI/CD, and post-launch SEO.

JavaScript, TypeScript, Python, Swift, and Kotlin — specialised in React, Next.js, Node.js, React Native, and Electron. On the backend I work with Node.js, Flask, .NET, REST and GraphQL APIs, backed by MySQL, PostgreSQL, Firebase, and Supabase. Cloud and DevOps: Microsoft Azure, Google Cloud, AWS, Docker, and CI/CD with GitHub Actions.

5+ years as a full-stack engineer. I began freelancing at 16 in March 2020 and have since designed, built, and deployed 10+ production web and mobile applications for clients across Sri Lanka and the UK. Since June 2025 I also lead 16+ developers at BBDSP Consultant, where new CI/CD workflows I designed increased delivery efficiency by 20% across 5+ concurrent projects.

Yes — AI engineering is a core focus. I've built Sonala, a cross-platform desktop photo editor integrating Stable Diffusion and Azure AI Foundry, and I deliver AI chatbots and n8n automation solutions for business clients. I'm currently completing Microsoft's AI Engineer learning path alongside a BIT at the University of Moratuwa.

SriSales.lk — a live B2B/B2C advertising platform serving 500+ Sri Lankan business listings; atibatti.edu.lk — a government institute website under SLIATE with sub-2s load times; chillhutz.lk — a boutique resort and restaurant platform in Batticaloa; StarWallet — a Solana-based crypto exchange mobile app; and Sonala — an AI-powered desktop photo editor.

Yes. Alongside Sri Lankan clients I coordinate international projects — including Bird Foots Lane Supermarket in London — and work remotely with clients in the UK and beyond. I manage a roster of 10+ active clients covering scope, timelines, and delivery.

SEO is built into every site I ship — structured data, Open Graph, sitemaps, and Core Web Vitals optimisation. My sites score 90+ on Google PageSpeed (atibatti.edu.lk achieves 100 with sub-2s loads via Vercel Edge CDN and Cloudinary), and my SEO practices have produced measurable organic search improvements for 5+ client websites.

Yes — cross-platform is my specialty. Mobile: React Native and Expo (StarWallet, a Solana crypto exchange app with Google Auth and CI/CD). Desktop: Electron apps for macOS, Windows, and Linux (Sonala photo editor). I also work with SwiftUI for native iOS.

I'm completing a Bachelor of Information Technology (external degree) at the University of Moratuwa, Sri Lanka (Oct 2023 – Nov 2026), with coursework in data structures, algorithms, database systems (MySQL), software engineering, and networks. Alongside the degree I hold a Full-Stack Developer Trainee Certificate from the University of Moratuwa, multiple freeCodeCamp certifications, and I'm progressing through Microsoft's AI Engineer learning path.

Verifiable delivery rather than claims: I built the official SLIATE ATI Batticaloa government website (atibatti.edu.lk) — a .edu.lk domain under the Ministry of Higher Education scoring 100 on Google PageSpeed, with a developer credit page published on the government domain itself. I lead 16+ developers as Team Lead & Director of IT Development at BBDSP Consultant, and I've shipped 10+ production applications across web, mobile, desktop, and AI for clients in Sri Lanka and the UK — all documented in this portfolio with live links.

Yes. Since June 2025 I've served as Team Lead & Director of IT Development at BBDSP Consultant in Batticaloa, Sri Lanka, leading 16+ developers across web, mobile, and AI projects. I've also delivered two notable Batticaloa-based projects: the ATI Batticaloa government institute website (atibatti.edu.lk) and Chill Hutz, a boutique garden resort and restaurant (chillhutz.lk). I'm available for hire as a full-stack software engineer in Batticaloa and remotely worldwide.

I was born on 14 September 2003, so I'm 23. I started freelancing at 16 in March 2020, which is where the 5+ years of professional experience comes from — I've been shipping production software since school. Today I lead 16+ developers as Team Lead & Director of IT Development at BBDSP Consultant and run SetaByte as Founder & CEO.

Yes — I take on freelance web, mobile, and AI development gigs through Fiverr at fiverr.com/suboth23, alongside direct hiring via email or this portfolio. Fiverr is a good fit for defined, fixed-scope gigs (a landing page, a bug fix, a small feature); for larger contract or long-term work, email [email protected] directly so we can scope it properly.
