About Yahia Hassan

I build mobile apps and SDKs, and I lead the teams that ship them.

Mobile Engineering Leader with 14+ years of engineering experience and 8+ years leading teams. Has led mixed iOS and Android teams of up to 11 engineers and builds reusable Kotlin SDKs — Bluetooth/BLE, the FTMS fitness protocol, PDF generation — that several client apps build on. Work spans telecommunications, IoT, fintech, sports, and public-sector projects.

Engineering & Leadership Specializations

Team Leadership & Scaling

8+ years leading mixed iOS and Android teams of up to 11 engineers — hiring, mentoring, performance reviews, and setting the technical direction the team works to.

Kotlin SDK Architecture

Modular Kotlin SDKs that several client apps build on rather than each reimplementing, covering problems as different as document and PDF generation, the FTMS fitness protocol, and Bluetooth/BLE connectivity.

Hardware & Device Integration

Getting mobile apps talking to physical devices: BLE and NFC integrations, custom sensor work, and GATT peripheral emulation for testing against hardware that isn't on your desk.

Cross-Domain Delivery

10–15 client projects delivered across telecommunications, sports, and public-sector domains, from Bundesliga club apps to city-government platforms — each with a different client, domain, and set of constraints.

Toolbox

Android Kotlin Swift Java C++ / C C# Python JavaScript SQL / NoSQL Bash Kotlin Multiplatform Jetpack Compose SwiftUI Coroutines & Flow MVVM / MVI TDD Bluetooth / BLE Network Communication Firebase Cordova REST & GraphQL Gradle & Maven CI/CD (Jenkins) Docker Distributed Systems Git

Background & Philosophy

Over the past 14+ years, I've worked across the full lifecycle of mobile application and SDK development, from early hardware-integration prototypes to telecommunications apps used by millions of people.

My core engineering focus is building reliable, testable, and reusable Kotlin SDKs. Keeping business and telemetry logic decoupled from the UI lets a team move quickly on the user-facing side without destabilising what sits underneath.

As a technical leader, I focus on clear communication, solid architectural standards, and pragmatic decisions that balance speed with long-term code quality.
