As a seasoned engineer with over five years in complex software systems across multiple industries (such as Logistics systems, HealthTech, EdTech, among others), I bridge the gap between complex technical challenges and accessible solutions. My expertise in cloud-based applications isn't just about writing code, it's about making technology work for people. Whether you're struggling with debugging code, designing efficient algorithms, or navigating complex system architectures, I've been in your shoes. I've developed enterprise applications from the ground up and guided hundreds of learners through challenges ranging from basic syntax errors to advanced architectural decisions. **What sets me apart? I don't just solve problems, I help you understand them. My approach combines hands-on engineering experience with a talent for explaining complex concepts in straightforward terms. From untangling complex code issues to optimizing system performance, I translate technical challenges into clear, actionable steps**. My greatest achievement isn't the systems I've built, it's watching my mentees transform from curious beginners to confident professionals. This journey has sharpened my ability to meet you exactly where you are—whether you need an expert to help resolve a persistent bug or a patient guide through new programming paradigms. **Let me help you turn technical obstacles into opportunities for growth.**

Freelance GitHub Developer - Tosin Felixson-Yusuf
Freelance GitHub Developer5.0 (43 reviews)

My experience has ranged from an individual software contributor, through as technical team lead. Cumulatively, I have about 7 years post qualification experience as a software engineer. I have worked with multiple technologies on projects where my role includes building software features, scaling existing legacy applications mentoring junior developers and ensuring product success. As a software engineer I think first in algorithms, data structure, design, analysis and architectural patterns when solving problems. I tend to think in a non language agnostic manner, however I favour some technological stack over others as defined: I have experience in Javascript, Python, Rust, Kotlin and C++. I have an excellent understanding of these language features and I have built solutions with regards. I also have decent skills in user interface development. And building backend services and RESTFUL Apis. I am currently running MSC in computer science with Georgia Tech.

Freelance GitHub Developer - Carlos Aguilar
Freelance GitHub Developer4.9 (67 reviews)

I’m a senior mobile + backend engineer with 20+ years in software (PHP since 2002; professional since 2005) and 10+ years building mobile apps. I help teams ship and stabilize real products—especially apps that are “almost done” but stuck on crashes, performance, flaky networking, or release blockers. What I can help you with (fast, practical): • iOS (Swift, SwiftUI, UIKit): crash fixes, performance/memory, concurrency issues, architecture cleanup • Flutter (iOS/Android/macOS): reliability, state consistency, networking/retry behavior, release readiness • Backend stability (PHP/Laravel or custom, Python/Django, Rails): idempotency, queues, DB performance, webhook safety • Firebase + mobile reliability: Auth/Firestore rules, Cloud Functions patterns, analytics/instrumentation • Monetization + shipping: RevenueCat/IAP reliability, App Store Connect/Play Console, CI/CD, rejection handling Recent work includes taking a messy iOS codebase (CakeClub) to production-ready with a Firebase Cloud Functions v2 backend, stronger security patterns, CI/release automation, and RevenueCat integration; and delivering major cross-platform Flutter work (BillBlaster) including design refinements, admin tooling, and push notification features. If you come with logs/screenshots (Crashlytics traces, network errors, repro steps), I’ll give you a clear diagnosis and a prioritized fix plan—and if it makes sense, I can execute the fixes as a focused sprint.

I’m a Unity developer with over 13 years in game development and more than 8 years working with Unity on mobile and VR projects. I enjoy helping solo developers and small teams. That can be learning Unity from scratch, starting a new project, or figuring out an existing codebase that feels confusing or messy. I’m happy to help with gameplay logic, debugging tricky issues, basic architecture questions, code reviews, and preparing for Unity or game development interviews.
