Senior software engineer with 5+ years of experience in backend web technologies including Ruby on Rails, Python, Go, and MySQL. Currently at Tesla, previously EasyPost. Bachelor's in Computer Science. Main strengths include architecting applications and backend API development, have also worked in fullstack roles. The best part of software engineering is that you never stop learning new things.
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.
If you need any assistance with a project or for mentoring, feel free to reach out. I'll do everything I can to make your project a success. Over the years many developers have helped me learn and improve. So, I'd like to do the same for others. I've done work for Shopify, Samsung, BP, Aldo, and many others. I've got a lot of real world experience developing useful software. My focus has always been writing simple code that easy to understand and maintain.
Hello, I'm Tyler! With a Bachelor's and Master's degree in Computer Engineering and over nine years of experience in the tech industry, I bring a wealth of knowledge and expertise to the table. I have worked on professional projects such as using Ruby to process x86 assembly instructions and using Python and React to show public transit arrival times. My experience across stacks and domains has led my passion to grow beyond just "getting code to work"; it's about unraveling the nuances of how software functions and exploring each layer of its construction. Throughout my professional career, I've taken immense joy in mentoring fellow engineers. Not long ago, I helped a junior engineer migrate some data processing code from a React Native application to a Kotlin application. This not only solidified their understanding of frontend versus backend development, but also enhanced my skills in explaining technical concepts in an accessible way. I approach teaching from a "First Principles" approach: if we can step back and understand the foundations underpinning each subject, we can dive into the details of a task or project with more confidence and resilience. I'm also excited to introduce a new guided Rust HTTP server project, which provides a deep dive into how an advanced library, similar to Axum, works under the hood. Over the course of five sessions, you'll gain hands-on experience in building a performant HTTP server from scratch, learning key concepts in Rust and network programming along the way. Lastly, I view code as a creative pursuit. Is it art? That's in the eye of the beholder. Having something functional is an critical step, but producing something clean and that you are proud of is my north star. I invite you to contact me with any questions or to discuss your specific learning goals. Let's work together to build your understanding and confidence in software and computer engineering!
