If you need a Python developer who actually delivers - you found one.

What You Get Right Now
- Free technical consultation. Tell me what you're building in Python - I'll give you honest feedback and a rough roadmap. No strings.
- Python codebase audit. Got an existing Python product? I'll find the weak spots before they cost you money.

Brands I've Worked With
• Carlsberg • ASUS • NielsenIQ • Virgin • Volvo • VW Group • Tetra Pak • Scania • Casio
These companies don't settle for "good enough." Neither do I.

Projects That Speak Louder Than Words

- EvenFlow AI - Python-driven AI platform. 20%+ revenue growth, $1.5M raised. Top 5% of SaaS companies by growth speed.

Tech I Live In
Python (Django, FastAPI, Flask) • AI/ML & LLMs • .NET Core • PHP (Laravel, Symfony, Yii) • Node.js • React • iOS (Swift, UIKit) • Android (Kotlin, Jetpack Compose) • Flutter • 3D (3ds Max, ZBrush, V-Ray, Substance Painter)

Industries: Healthcare, FinTech, eCommerce, Automotive, SaaS, CRM/ERP, Marketplaces

How I Work
- Weekly reports. NDA as standard. I test everything - functional, regression, API, cross-browser. Quality is baked in from day one, not patched in later.

Got a Python project? Here's my offer - free technical consultation and a Python codebase audit.
Tell me what you're building in Python or send over your Python repo, and I'll give you a straight assessment: what's solid, what needs work, and how to move forward.
