Have a product idea?I ship it in weeks.
Senior engineer with experience at major companies. I use AI to design, develop, and deliver complete software products, from idea to production, at team speed, one-person cost.

What I Build
You have the idea. I build the product.
MVP in Weeks
I turn your idea into a working product, with solid architecture, clean code, and production deploy. No months of planning. No team to assemble.
Complete Applications
Web apps, APIs, dashboards, SaaS platforms. I design, develop, test, and deliver complete systems ready to scale, with the quality of someone who has done this at major companies.
AI Built Into the Product
I build products with AI at the core: smart automations, data processing, conversational interfaces. Not as a decorative feature, as a real differentiator.
Why a solo engineer?
Assembling a team to build a product takes months before writing the first line of code. Recruiting, onboarding, alignment, sprints. AI changed that reality. A senior engineer with AI designs, develops, and delivers what used to require an entire squad.
I am that shortcut. Real experience building systems + AI as force multiplier = your product live, without the overhead of a team.

About
I built real products inside large companies.
I built platforms from scratch in healthcare, finance, and e-commerce. I saw how products are born inside major companies and how much time is wasted before writing the first line of code.
When generative AI exploded, I realized something few admitted: it doesn't replace bad programmers. It multiplies good ones. A senior engineer who knows what to build and uses AI to build faster delivers what an entire squad used to deliver.
Today I build complete products for those who have the idea but not the team. From concept to deploy. One person, AI as a tool, and the experience of someone who has done this at the biggest companies in the market.
Picture This
You have an idea. What you need is someone to build it.
The Problem
You have the concept, the market, the opportunity. But assembling a technical team takes months. Hiring, aligning, managing. And by the time the product ships, the window has closed. That model made sense before AI. It doesn't anymore.
No months of recruiting. No onboarding. You describe the idea, I deliver the working product, with architecture, code, tests, and deploy.
No splitting attention across 5 clients. Each project gets complete dedication. You talk directly to the person building it, no middlemen.
Your product is born with solid architecture and patterns tested in real production. Code that scales, not code that survives.
What is blocking your project today
Project Types
What I build.
You have a SaaS idea but no technical team. You need a working product to validate in the market, acquire customers, or raise investment.
Complete application with authentication, dashboard, API, database, and automated deploy. Ready for first users.
Working product in production in weeks. Clean, documented code ready to scale when the business grows.
Projects
What is live.
Contrast
What You Get
A complete product. Not a partial deliverable.
How It Works
From idea to product. 3 steps.
TALK
- You tell me the idea and context
- I evaluate technical feasibility and scope
- We leave with a clear plan of what will be built
DESIGN
- Architecture, stack, and timeline defined
- Fixed scope with deadline and clear investment
- You approve before I write a single line
BUILD
- Complete product in production
- Documentation for your future team
- Code that scales, ready to grow
Commitment
Your product. My responsibility.
Every project has a fixed scope with clear deadlines and deliverables. If within the first week you don't see value in what's being built, the project stops at no cost. No long contracts, no surprises, no catch.
Confidence comes from competence, not contracts.
Next Step
Have an idea? Let's bring it to life.
Currently accepting 2 new projects per month to ensure every client gets complete dedication, not surface-level delivery.
