Hire Top Freelance Coroutines Developers

Damián Rafael Lattenero

# 👋 Hi, I’m Damián **Senior Software Engineer** with 10+ years turning ideas into _real, working code_ — using **Kotlin**, **Java**, **Python**, **Haskell**, **JavaScript**, and **SQL**. --- ### 🚀 But here’s what really matters: I know how overwhelming programming can feel — and I’m *really* good at making it make sense. Whether you're: - A **beginner** who thinks `if` statements are witchcraft, - In **university or bootcamp** and your code feels like a tragic love story, - Or a **pro** getting roasted by a bug that mocks your debugger — **I’m here to help.** --- ## 🧠 How I Can Help ### **📍 Starting from zero?** - Learn **Python, Java, Kotlin, or Haskell** — no overwhelm, no nonsense. - Understand **core concepts**: variables, loops, functions — *and why they matter*. - Build **real projects**, not just toy examples. - Stop copy-pasting code you don’t understand — I’ll help you _actually get it_. --- ### **🎓 In school or bootcamp?** - Tackle **assignments** with clear explanations — not just magic answers. - Design class hierarchies that *actually make sense*. - Debug weird, soul-crushing errors. - Start **thinking like a developer**, not just surviving syntax. --- ### **💼 Already coding professionally?** - Write **meaningful tests** (JUnit, Mockito, pytest — no excuses). - Migrate from **Java → Kotlin** or **OOP → FP** — _without the pain_. - Work confidently with **Spring Boot, GraphQL, PostgreSQL, MySQL**. - Refactor legacy code for **clarity, speed, and sanity**. - Finally grasp **functional programming** — yes, *even monads* (no PhD needed). --- ## 🎯 My Teaching Style - **No ego, no jargon** → Ask anything. I’ll meet you where you are. - **"Why" over "what"** → I’ll help you _understand_, not just repeat. - **Adaptable & fun** → If cat memes help you learn, I’ll bring the cats. 🐱 --- ## ✅ Bottom line? Whether you’re stuck, starting out, or leveling up — **we’ll make progress, one clear concept at a time.**

Paul Hansen

I've been blessed with many wonderful opportunities throughout my career, which have helped me grow not only as a professional, but as a person. My greatest pleasure comes from witnessing the transformation of a mentoree in both confidence and knowledge! When I'm done with work for the day I transition to my own open source projects: ranging from - zero-dependency DI framework in Kotlin - persistent/immutable data structure library in Kotlin I'm learning K8s by running a raspberry pi cluster in a basement server rack for home automation. Enough about me, let's get to work on improving your current situation!

Juan Gabriel Gutierrez

My name is Juan, and I'm Juan in a million :) I enjoy to have challenges in my daily life so for that reason I learned to code almost 17yrs ago. I've made software for Bash, Desktop, Web, and Mobile for many types of projects. I started learning Objective-C around 12yrs ago when I decided to focus on creating mobile apps. Currently, I make Android apps most of the time for companies in the USA from Medellin, Colombia. However, I love to explore new mobile technologies in my side projects, and if I had the opportunity, I would like to release more things as open source to my Github profile like a contact-tracing PoC with Bluetooth that I did some months during the Pandemic.

Atiq R.

I build Android apps that actually scale. 9 years solo dev. Built 2 apps from scratch to 1M+ downloads each, maintained 5-6 app portfolio (90M+ combined downloads) for the last 5 years. I own complete cycles - architecture, implementation, deployment, maintenance. Performance-critical work: offline-first apps, audio processing, kept crash rates under 1%. Used XML over Compose because speed mattered more than hype. Kotlin, MVVM, Coroutines, Flow in production at scale. Room, Retrofit, Firebase. Top 1% Stack Overflow (14k rep, Android). Ran Kotlin workshops at GDG events. I ship fast, communicate clearly in English, don't need hand-holding. Been solo for 5 years - that's both good (can own features end-to-end) and bad (limited CI/CD practice, no recent team experience). Ready to work with actual teams again. Want teams that care about shipping working products.
