I've worked at Beyondsoft Technology and Century Games before going independent. Now I focus on helping startups and businesses build reliable, scalable products from scratch or improve existing ones.
I take full ownership of projects — from requirements and architecture to deployment and post-launch support. Clear communication, on-time delivery, and clean code are non-negotiable for me.
Open to both fixed-price and hourly projects. Let's talk about what you need.
