I'm Olateju Olamide, a Mobile Engineer focused on building modern, useful, and maintainable mobile applications.

My primary stack is React Native, TypeScript, and Expo. I care about both engineering and experience — building applications that are reliable, responsive, understandable, and enjoyable to use.

I've built across faith, education, healthcare, language, productivity, audio, and fintech, learning each problem from the ground up and turning ideas into working products.

Beyond mobile, I work with backend systems, AI/ML, web technologies, Linux, and developer tooling.

I don't just want to write more code.

I want to build things that are useful, resilient, and meaningful.

Faith · Prayer · Spiritual Discipline

A prayer companion built to help believers turn good intentions into consistent spiritual practice through prayer plans, reminders, fasting, journaling, testimonies, and reflection.

Status: Live Soon · Source Code

Faith · Scripture · Meditation · Declarations

A Scripture meditation and declaration app built around the King James Version (KJV) and Strong's Concordance.

Hagah helps users speak, study, remember, and repeatedly engage with Scripture through declarations, meditation, reminders, text-to-speech, and shareable content.

Status: Available on Google Play · Google Play · Source Code

Language · Culture · Pronunciation · Audio

A tone-first Yorùbá learning experience focused on pronunciation, vocabulary, conversation, native-speaker audio, and repetition.

The goal is to help learners hear, pronounce, understand, and use Yorùbá — not simply translate it.

Status: In Development · Source Code

Faith · Study · Knowledge

A Bible study and sermon note-taking workspace bringing Scripture, study resources, search, quizzes, and personal notes into one focused environment.

Status: In Development · Source Code

AI · Audio · Productivity

An AI-powered audio experiment exploring speaker diarization, transcription, timestamps, and structured meeting information.

Status: Prototype · Source Code

Healthcare · Computer Vision · On-device AI

An AI-assisted mobile healthcare prototype exploring computer vision and on-device machine learning for neonatal jaundice screening.

Status: Prototype

Fintech · Payments · Group Commerce

A group cost-sharing concept designed around making shared purchases and payment settlement simpler.

Status: In Development

Faith · Content · Sharing

A lightweight devotional app built around daily quotes, reminders, visual cards, and easy sharing.

Status: Available · Google Play · Source Code

Education · Linux · Gamification

A practical Linux learning environment combining command references, quizzes, challenges, progress tracking, and spaced repetition.

Understand → Design → Build → Break → Fix → Improve → Ship

I enjoy the parts of engineering that happen beneath the surface:

Architecture decisions.

Debugging.

Performance problems.

Edge cases.

The awkward first implementation.

The UI that looks fine until someone actually uses it.

That's where engineering happens.

• Advanced React Native architecture
• Mobile performance engineering
• Native platform integration
• Backend architecture
• System design
• AI + mobile integration
• Speech and computer vision
• Database and data modeling
• Interface design
• Production engineering

Good software solves a real problem.

Beautiful interfaces mean little if the underlying system is fragile.

Engineering is as much about understanding constraints as it is about writing code.

The first version doesn't have to be perfect. It has to teach you something.

Build it. Break it. Understand why. Fix it. Build it better.
