Available for freelance & contract work
I'm Prathieshna, a mobile technical lead with nine years of experience building and shipping production Android apps for logistics, fintech, open-source and travel teams. I also teach software engineering at university level.
About
I lead mobile engineering from the first design discussion to the Play Store release and the years of maintenance after it. I have worked on warehouse systems used across a global distribution network, a fintech platform and open-source archiving tools, and I run my own products alongside client work.
Outside client work I lecture at universities in Colombo and mentor engineers, so I'm comfortable explaining technical decisions to developers, designers and business owners alike.
Clean architecture and code review, so the app is still easy to change in year three.
Plain updates, honest estimates and no surprises during delivery.
Encrypted storage and transport, least-privilege permissions and compliant releases.
Selected work
Four apps I own end to end, from the first commit to the store listing.
Android & Android TV
Turns any TV into a sign from your phone. Push slides, run a countdown timer, read from a teleprompter or call queue numbers, all over the local Wi-Fi. Content is encrypted between the phone and the TV, and there is no cloud and no account to create.
Android
Private field notes with photos, voice and GPS. Everything is encrypted on the phone, voice notes are transcribed on-device, and photos can be signed with Content Credentials so later edits show. No account, no cloud, no server.
Android
Searches millions of books through the Google Books and Open Library APIs. Covers, ratings, community reading stats and publisher details in a single, fast app.
Android · Sri Lanka
A step-by-step estimator for Sri Lankan personal income tax. Plain-English questions lead to a line-by-line breakdown for every Year of Assessment from 2018/19 to 2026/27, including residency relief and deductions.
Services
End-to-end mobile development, architecture and consulting, from a brand-new app to modernising a legacy one.
Native Kotlin apps from concept to Google Play, with clean architecture, smooth Compose UI and code that scales with your product.
Flutter or React Native when one codebase should serve iOS and Android, without giving up a native feel.
REST design and integration, OAuth and Keycloak authentication, Firebase, and backend work in Node.js and Next.js.
Declarative interfaces with fluid animation, custom components, edge-to-edge layouts and Material 3 design systems built to spec.
SDK migrations, Play Store compliance, bug fixes and new features on existing codebases, delivered without downtime.
Architecture reviews, code audits, mentoring and mobile strategy, as hourly advisory or an embedded technical lead.
Tools
Native Android first, with cross-platform and backend tools when the project calls for them. Practised daily: MVVM and clean architecture, modular builds, dependency injection with Hilt and Dagger, code review and Agile delivery.
Logos are from Simple Icons (CC0). All product names and logos are trademarks of their respective owners and appear here only to show the tools I use.
