Android,
engineered for
the moment.

I design and build production Android apps, SDKs, and multiplatform systems, across phones, watches, and custom hardware.

01 / SELECTED WORK

Where product pressure meets platform craft.

The most interesting Android work is rarely just a screen. It is business rules, unreliable networks, hardware, compliance, and human expectations converging in one tap.

01
Priceline2026 - NOW

Complex journeys, kept coherent.

Building features across flights, hotels, and car rentals for Priceline's North American Android team, inside a large production codebase.

Kotlin and Kotlin Multiplatform keep eligibility, pricing, and state consistent where every edge case sits close to conversion.

  • KMP
  • Large codebase
  • Travel

02
FairMoney2025

A phone number became a bank account.

Implemented a Kotlin Multiplatform feature that helps more than 10 million customers receive transfers using the number already in their contacts.

Shared business logic and a bank-suggestion algorithm reduced platform drift and removed friction from a high-frequency transfer journey.

  • Banking
  • 10M+ users

Orda Africa2023 - 2025

One codebase. Many devices.

Led Android development for a merchant app that ran across multiple terminal environments from a single codebase.

Reusable device integrations, modular architecture, and features like clerk-aware tipping turned hardware constraints into a consistent merchant experience.

FIELD NOTE / 01
Good mobile engineering makes difficult systems feel obvious.

That means staying close to the product, designing boundaries that survive change, and treating reliability as part of the experience.

02 / THE CRAFT

How I build Android.

Strong foundations first: clear architecture, honest state, and code a team can keep changing for years.

01

Architecture

MVVM and MVI, modular boundaries, and dependency injection with Hilt or Koin, so large codebases stay easy to change.

  • MVVM / MVI
  • Modularisation
  • Hilt / Koin
02

Jetpack Compose

New UI in Compose and careful migration of legacy XML screens, including work used by 50,000+ agents.

  • Compose
  • XML migration
  • Design systems
03

Kotlin Multiplatform

Shared domain logic and state handling across platforms, with clear ownership and fewer client-specific defects.

  • KMP
  • Compose Multiplatform
  • Shared modules
04

Quality & reliability

Code review, regression validation, crash investigation, and tests that make releases boring in the best way.

  • Espresso
  • Unit testing
  • Crashlytics
05

SDKs & integrations

Reusable SDKs, REST and GraphQL integrations, and device-level work across OEM hardware.

  • SDK design
  • REST / GraphQL
  • Device APIs
06

Leadership

Led Android teams and a frontend function, mentored engineers, and aligned product, backend, QA, and release partners.

  • Team lead
  • Mentoring
  • Delivery
IN PRACTICE

Predictable state. Unsurprising UI.

I model screens as explicit states, so loading, success, and failure are all first-class and testable. Failure is a state the user can recover from, not an exception the UI forgot to handle.

Illustrative example, not production code.

03 / EXPERIENCE

From the hardware layer to the whole product.

My career began close to the metal: custom devices, SDKs, and OEM quirks. Each chapter since has widened the frame, from libraries to teams, and from single features to whole products across travel, banking, and hospitality.
