Freelance Ruby Developer - Abdurrachman M
Freelance Ruby Developer5.0 (104 reviews)

Website: https://linktr.ee/YoKulGuy --- I'm a realist, aspiring general system thinker, and software craftsman. Despite specialists giving much contribution and productivity to society, general system thinkers and their general system thinking can help us solve the second-order effect of human creation. As a society, we build civilization; we build skyscrapers, aeroplanes, gadgets, and all the advancements in technology, but we overlooked the second-order effect of our creation. Global warming and gadget addictions are an example to name a few. The more people adopt general system thinking, the more we can achieve a better society and brings our world to the next thousand years. I do research and craft code as my way of expressing my idea and belief. I crafted a scientific computation tool and instrument to help researchers do better research when I was in college. I led a team in a startup called Mekari to empower businesses in Indonesia. I previously worked at Midtrans, enabling software developers to be more productive and better empower commerce through technology. I write production code in Elm, JavaScript, Bash, Ruby, and Java. In 2020 I did functional programming on Elm and built a community around it. Feel free to reach out to me if you are an Elm user!

I'm a multi-talented senior-level developer with a focus in webdev and Linux servers, and have experience working with various sorts of code on various projects. I have very strong troubleshooting skills, am adept at learning new tech, and have some secondary cybersecurity experience (such as conducting informal security audits). I'm enthusiastic about sharing knowledge, am practiced at explaining how code works, and am eager to help people learn about programming! Availability is typically 11am - 11pm local time (UTC+7), although I have an hour or two of flexibility on that.

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.

Freelance Ruby Developer - Paul Gasbarra
Freelance Ruby Developer

Hi there, I'm Paul. I live in New Jersey. I’ve been a developer for 9 years now. I came to software development because I love to create things. I love it when people use those things, and I love it when those things help people. I come from a creative writing background which is very different from software development but there is a lot of similarities between a well crafted piece of writing and a well crafted bit of code. Since I began coding, I’ve built digital museums, multi-device shopping experiences, commuter facing kiosks, and mall directories. I want to keep on building really cool and useful things, share my knowledge with others. I'm well versed in Javascript, Typescript, React, Redux and associated Front End technologies. I can't wait to help you out.
