From MVP to Production — Full-Stack Engineering for Startups
Spring Boot + React/Next.js applications with AI integration baked in. Think of it as hiring a CTO who also writes the code.
The Problem
You're a startup founder who needs a technical co-founder but can't afford one. Agencies deliver cookie-cutter solutions and lock you into long timelines. Junior freelancers build things that break at 100 users. You need someone who can make architecture decisions, write production code, and ship — all without a 6-month timeline.

Frequently Asked Questions
How do you choose between different tech stacks?
I pick the stack based on your business needs, not trends. Spring Boot + Java for backend-heavy apps that need reliability and performance. Next.js for SEO-critical marketing sites and content platforms. React Native for mobile. PostgreSQL for most databases. I'll explain every choice and trade-off before writing a line of code.
Why hire a freelancer instead of an agency?
Agencies assign junior developers to your project and charge senior rates. With me, you get the same senior engineer from day one to deployment. No project manager telephone game, no surprise billing, no handoff between teams. I've built and shipped 6+ production systems — you're hiring the person who does the actual work.
How do we get started?
Send me a message describing what you want to build. I'll reply within 24 hours with initial thoughts. We then do a free 30-minute call to discuss scope, timeline, and budget. If we're aligned, I send a detailed proposal with milestones and fixed pricing. No hourly billing surprises.
