Iede Snoek

When I left university (with two degrees), I decided to work in ICT. My first job at the largest newspaper here in the Netherlands, I worked on the search engine (a recurring theme in my career) and the ad-management on their website. After that I went into a mutitude of jobs, the last 10 years however I more or less specialized in C# (and .NET Core when it became available). Nowadays I am looking at Rust and Go.

# 👋 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.**
