Technical Versatility
I work across the full stack – from modern frontend frameworks like React and Astro to backend technologies like Node.js and Express.js
Business-Oriented Thinking
I ask the right questions and build solutions that serve real business goals – not just code that works.
Clear Communication
You get regular updates, transparent workflows, and no guesswork. You stay in control at every stage.
Design + Development

Performance Matters
I prioritize fast-loading, SEO-friendly websites that deliver great user experience on every device.
Reliable & Accountable
Deadlines, quality, and honesty - I treat every project as if it were my own product.
