Cairo, EG / Senior Android Engineer & Mobile Architect

Michael SamSenior Android Engineer & Mobile Architect

I build mobile systems that survive production: robot interfaces, OCPP charging networks, live auction streaming, fintech wallets, and offline-first Android tools.

Michael Samuel Naeem, senior Android developer and tech lead based in Cairo, Egypt.

I am Michael Samuel Naeem, a senior Android developer and mobile architect with 10+ years shipping production apps and 4+ years leading engineers. I work closest to the places where mobile UX, backend contracts, real-time systems, and release quality meet.

  • Architected Android and Flutter systems for EV charging, robotics, fintech, e-commerce, live streaming, and developer tooling.
  • Led teams of 4-6 engineers while staying hands-on with Kotlin, Jetpack Compose, Flutter, architecture, performance, and release quality.
  • Shipped public Google Play apps and VS Code extensions under MichaelSam94, with static documentation and crawlable product pages.
  • Comfortable joining messy systems: audit the risk, name the tradeoffs, reduce ambiguity, then ship the next useful milestone.
Can you help my team ship a reliable Android app?

Yes. I build Kotlin and Jetpack Compose apps with cleaner architecture, faster screens, fewer crashes, and releases your team can trust.

What do you bring beyond writing code?

Architecture judgement, delivery sequencing, mentoring, code review, production debugging, and the ability to make technical tradeoffs plain.

Can we work together outside Egypt?

Yes. I am based in Cairo and work with remote teams across the United States, Europe, the Gulf region, and nearby time zones.

What projects are the strongest fit?

Android, Kotlin, Flutter, real-time systems, OCPP, EV charging, robotics interfaces, developer tools, AI automation, and production rescue work.

What should you send first?

Send the product goal, current stack, affected users, deadline, and any crash logs, screenshots, store reviews, or short recordings.

How do we start?

We agree on the outcome, map the riskiest parts, and choose the smallest useful milestone before writing more code.

What happens when something is risky?

I will say it plainly, explain the tradeoff, and propose a practical path if scope, architecture, or timeline looks fragile.

Can you join an existing team?

Yes. I can pair with your team, review pull requests, lead a feature stream, or help Android, Flutter, React, and backend work connect.

Optional side creative work, kept separate from the core engineering case. The main hiring signal on this portfolio is senior Android engineering, mobile architecture, production systems, and developer tools; these reels are only a glimpse of product storytelling instincts.
