Welcome to Warky Devs
Warky Devs started with one engineer and a simple conviction: software should be built properly and maintained for the long run. I keep architecture simple, execution efficient, and every line of code maintained. I don't chase trends — I deliver lasting solutions. Engineer DNA. Full Stack. Maintained.
Who I Am
I'm Hein Puth — a developer and engineer with a passion for solving complex problems. I've been in software development since 2006, working alongside senior developers for many years and building deep expertise across a wide range of industries and technologies. Over time, I've developed an approach that combines technical understanding, experience, and context to navigate challenges, identify underlying patterns, and arrive at practical solutions.
I established Warky Devs in 2021, guided by a focus on simplicity, efficiency, and effectiveness. I value clear thinking, practical execution, and delivering meaningful results while avoiding unnecessary complexity and bureaucracy.

My Expertise
I'm a versatile problem-solver proficient in multiple programming languages including Go, Rust, JavaScript, TypeScript, Dart, C#, C++, Python 3, Lua, and more. From frontend to backend and everything in between, I pick the right tool for the job and build it properly.
I'm familiar with modern frameworks including React, Svelte, Next.js, and TanStack. My specialisation in database and data-driven application development turns raw data into actionable insights. I'm also well-versed in AI integration, working with modern AI technologies and models to build intelligent solutions.
