Building mobile products that ship.

I'm Bahi Mohamed Elfeky — Mobile Technical Lead and Senior iOS engineer with 7+ years delivering high-traffic mobile apps. I lead cross-functional squads while staying hands-on, specializing in iOS Flutter and clean, scalable architecture.

Seven years of shipping mobile.

I split my days between writing Swift and Dart, leading a cross-functional squad — iOS, Android, backend, QA — and shipping mobile features that real people use every day.

At Paysky I own mobile strategy across the squad: Clean Architecture and Strategy patterns for the complex payment flows, payment-link flows, legacy migrations, and an organization-wide Engineering Evaluation System I designed — custom KPI and OKR frameworks that standardize seniority and performance across the team.

I optimize delivery velocity by integrating AI agents, Model Context Protocols (MCP) and automation into the engineering workflow. The job, end of the day, is to bridge product and technical execution — scalable, secure, maintainable codebases for mission-critical apps.

[ 04 / leadership ]

How I lead a squad.

  1. P.01

    Lead, but stay hands-on.

    I still write Swift and Dart on a daily basis. The day a lead stops reading the diff is the day the architecture starts drifting. Title is no excuse to log out of Xcode.

  2. P.02

    Clean architecture is a gift to your future juniors.

    SOLID, Clean Architecture, Strategy patterns — not for the code review. For the engineer who'll inherit the payment flow at 2am, eighteen months from now, and need it to make sense.

  3. P.03

    Bridge product and technical execution.

    My job sits between the spec and the ship. Translate ambiguity into commits, surface risk early, and refuse to defend a deadline past the moment it stops being useful.

  4. P.04

    Standardize seniority with frameworks people can argue with.

    I designed our org-wide engineering eval system on KPIs and OKRs — not to grade people, but to make career conversations concrete. Vague feedback is no feedback.

  5. P.05

    Automate the boring. Integrate AI where it pays.

    AI agents, Model Context Protocols, CI automation — I bring them into the workflow when they save real hours, not because the keynote said so. Velocity is the goal, not the demo.

  6. P.06

    Scalable, secure, maintainable — pick three.

    Fintech doesn't let you choose two — and any mission-critical app is no different. Every choice — from architecture pattern to dependency lock — is a security decision and a maintenance decision at once.
