SDE(iOS Developer)
🚀 iOS Software Engineer | Swift • Scalable iOS Architectures
🎙️ 3× Global Speaker (Mobius, AppsConf X 🇷🇺 & MDW 2025 🇦🇪)
I’m a Software Development Engineer (iOS) , focused on building production-grade iOS applications that scale reliably and age well. I specialize in Swift-first development, MVVM architecture, and data-driven mobile systems using Realm, with a strong emphasis on performance, stability, and long-term maintainability.
My day-to-day work involves solving hard engineering problems rather than surface-level fixes—working closely with product, backend, QA, and design teams to ship features that are cleanly architected, thoroughly tested, and resilient under real-world usage. I care deeply about code quality, app performance, and user experience, and I optimize for all three without trade-offs.
In addition to iOS, I bring solid cross-platform and frontend experience, working with React.js, TypeScript, C#, and Power BI, along with Microsoft BI technologies such as SSIS and SSAS. This allows me to think beyond mobile screens and contribute meaningfully to end-to-end product ecosystems when required.
🎙️ I’m also a global speaker and educator, having delivered technical talks at international and large-scale platforms including Mobius, AppsConf X (Russia), MDW 2025 (UAE), GDG DevFest, IEEE Computer Society, AWS Dehradun, Delhi Flutter, and the Nigeria Technical Community. My sessions are known for being practical, system-level, and grounded in real production experience—not theory slides.
🎓 Mentorship is a core part of my journey. As a hackathon mentor and judge, I’ve helped developers transform early ideas into shippable products, guiding them on architecture, execution, and engineering discipline. My contributions to the developer ecosystem have been recognized with honors such as the 21 Under 21 Award.
📚 Outside engineering, I’m an author. My debut novel, A Letting Go: Journey of Rediscovery, explores emotional resilience, self-growth, and the realities of college life. Writing keeps me grounded and sharpens the same clarity and empathy I bring to engineering and leadership.

Async/Await at Scale: Designing High-Throughput iOS Architectures
Swift's async/await made concurrency look simple but shipping it at scale is still a boss-level problem. With Swift 6's strict concurrency breaking 70% of existing codebases, most production apps are now drowning in hidden race conditions, silently cancelled tasks, and background work that behaves like a sleepy security guard.
This talk breaks down how we designed an iOS architecture handling 10,000+ concurrent async operations without melting CPUs or spiraling into Task-hierarchy spaghetti. We'll go deep into structured concurrency, task lifetimes, cancellation propagation, actor re-entrancy traps, and the most underrated weapon in Swift concurrency: backpressure the technique that keeps your app smooth even when everything is happening at once.
