Ilya Demidov

Your tech partner

Transforming your "Big Idea" into a scalable, secure, and investor-ready reality

I'm not an IT freelancer

I don't code what you say

I don't bring a technology just to try it

I don't say "no risk" if it is

I challenge your idea and if it fails, I help you brainstorm other alternatives

I use exactly needed technologies only, but that don't disable further development

I say openly what risks we have doing these or that things

Stop Feeling Like a Hostage to Your Own Tech

You have a great product idea, but right now, the development process feels like a black box you’re afraid to open. If you’ve run products before, you already know the nightmare: developers who say “yes” to everything, build exactly what you ask for, and leave you with a bloated, unmarketable mess that you have to scrap in six months.

You don’t need another order-taker. You need a Strategic CTO Partner who actually carries the weight of the technology with you.

I act as your technical translator and business-first architect. No tech-speak, no hidden surprises—just total clarity on how your software serves your business goals.

I am not a "Yes-Man." If an idea will drain your budget, over-engineer your MVP, or break your system, I will ruthlessly challenge it and find a smarter, leaner way to reach your goal. I handle the architecture, the security, and the servers so you can stop playing tech support and stay focused on your growth.

How I Help You Launch

The "Zero to One" MVP

 

I’ll build not just a prototype, I’ll build a robust, high-load foundation that proves your concept and impresses investors.

Your Personal Tech Guardian

 

I assess security risks and implement protection from day one. Your users' trust is your most valuable asset. I’m here to guard it.

Data with a Purpose

 

I’ll build the systems to capture insights, helping you understand your users' needs and make decisions with total clarity

Why Work With a CTO Partner?

Founders usually think they only have two choices: hire a cheap freelancer who write code what you say, or pay a massive agency that drains their runway without caring about the product.

I offer the third way.

With 15 years of technical architecture experience, I’ve seen exactly why software fails and what makes it fly. I strip away the corporate bloat and bring hardened, secure architecture to the startup world.

I ensure your MVP isn't just a fragile prototype you have to rewrite next month, it is a lean, bulletproof foundation engineered to validate your market today and scale seamlessly as you grow.

About me

ABOUT ME

Having engineered systems for banks and insurance giants more than 15 years, I know how to build rock-solid infrastructure. But I also saw how projects get crushed by heavy, expensive corporate tech stacks.

Last 5 years, I do the opposite for startups.

I completely skip the bureaucratic, over-engineered tools. Instead, I curate only the top 1% of ultra-lean, modern technologies. These tools let us move with lightning startup speed while delivering the battle-tested reliability, data security, and stability required by major institutions.

I’m here to ensure your technology is lightweight enough to pivot fast, yet secure enough that you never have to rebuild.
