Engineer × Product Builder
I don't just write code — I solve real business problems, building products that actually work for people, especially when you need something shipped yesterday.
How I Work
- Question everything — understanding the *why* behind every feature.
- Ship, measure, adjust — because perfect is the enemy of done.
- Focus on real users and real problems, not just tech trends.
- Build with purpose — creating technology that genuinely helps.
What You Get
- Working prototypes — ideas to clickable demos in weeks, not months.
- Cost-effective solutions that optimize, not just rebuild.
- Expert contract development (Javascript, PHP, Python).
