# 👋 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.**
Expert at developing high-quality software solutions that leverage appropriate automation techniques.
Looking forward to pair programming with you on your problem!
Done a heck of a lot of programming and software design since I wrote my first on a Sinclair ZX spectrum in 1987. Not enough of it has been made open source. 2000+ five star ratings
### About Me
I am an experienced **AI and Computer Vision Specialist** with a **Master’s degree in Computer Vision** and a recipient of the **Google Inside Look 2019 Award**.
