What I do

I help companies turn an idea into a working system — I design it and deliver it myself. From a fast MVP, through automations and SaaS, to a standing CTO role alongside your team.

01 /
Prototypes & MVP
Rapid idea validation. A working product in 5-7 days that you can show investors and early customers.
5-7 daysfrom 10,000 PLN
02 /
Internal tools
Automations, CRMs, integrations. Products that streamline processes, pay for themselves in weeks, not years.
9-14 daysfrom 25,000 PLN
03 /
SaaS products
Production-ready software built to scale. Architecture, security, tests — everything that separates a prototype from a real product.
15-25 daysfrom 50,000 PLN

CTO as a Service
Tech advisory for founders and teams. Audit, stack selection, AI strategy, hiring and team mentoring.

Why work with me

I've been on both sides of the table, I've built companies and written the code for them. I know when a beautiful proof-of-concept should stay a proof-of-concept, and when it should go to production and serve hundreds of thousands of users.

My name is Bartosz Rychlicki. For the past 20 years I've been building companies, products and teams. I started with an interactive agency at 19, through Quantum CX (deployments at PKO BP, Orange, Santander), to crypto fund Seneka Fund.

Today I combine business experience with AI. I'm not a typical software house, I'm an entrepreneur who can code and understands what companies really need.

AI Development

Day-to-day I lead AI development at Pirxey as Head of AI Development. Hands-on practice with the latest models, agents and dev tools — not one-off projects once a quarter.

IT & Programming

Served as CTO, built many products for myself and others. Technical education, experience as a programmer and system architect.

Business & processes

I ran tech startups and service businesses. I understand how companies work, and where they lose money.

Creativity

I come up with solutions others overlook. I combine technology with business-product thinking.

§ 03b / Owner mindsetreceived message
I feel you've become a bit of an owner of this product, and I appreciate it. That's actually what makes you stand out. Bloody great mix.

What this means

That is not a compliment. That is a job description.

Most companies hire three people: a Business Analyst who understands the business and turns it into requirements. A CTO who picks the stack and the architecture. A Product Owner who carries the vision forward. Three people, three rates, three calendars, three interpretations of the same problem — and they do not always agree.

With me you get all three in one person. One rate. Zero handoffs. Zero "not my department".

01 /

Business Analyst

I walk into your business — or your client's business — and understand it. I map processes, gather requirements, turn them into a product vision before anyone writes a line of code.

discoveryprocessesrequirements
02 /

CTO / Developer

I pick stack for the problem, not for my CV. I design architecture for 12 months, not for a demo.

stackarchitectureproduction code
03 /

Product Owner

I own the vision, decide what is MVP and what waits, and carry the roadmap forward. I make sure the product keeps answering the real problem after launch, not the whim of the week.

§ 04 / Important distinctionread carefully

✕ Important distinction

This is NOT a prototyping shop

I clearly distinguish what I do from quick prototyping tools. I build professional software that works in production.

✕

Prototyping toys

Great for quick tests and idea visualization, but not for production:

LovableBoltBase44Cursor/v0and other "vibe coding"
  • Limited scalability
  • Difficulty in further development
  • No control over code
  • Security issues
✓

Professional software

Production code you can deploy and develop for years:

  • Proven architectural patterns
  • Planned architecture and infrastructure
  • 100% your code — no vendor lock-in

§ 05 / How I work04 stages

Process

Four stages from idea to working product. Each one closes with your sign-off before we move on — no surprises at the end.

1/
Discovery
I gather requirements, understand the business problem and the users. We agree on scope, priorities and success criteria.
2/
Prototype
I build a clickable prototype that shows the full user flow and UI. We iterate until you say "yes, this is it".
3/
Build
Once the prototype is approved, I move into coding — production architecture, tests, integrations. You see progress every day.
4/
Deployment
I ship to production and stay for upkeep — monitoring, fixes, new features. The code is 100% yours.

§ 07 / FAQ7 questions

Frequently asked

Have doubts? Check answers to the most popular questions.

01
I've heard AI-generated code quality is poor and you can't build a working application.
That was true a few months ago. Today AI models get better month by month, and the strongest ones outperform most programmers on skills tests. But they require supervision. That's where I come in — 20 years of programming and architecture means I know what AI does well and what it misses.
02
We build a system, and then what?
The code is 100% yours. You can develop it with any team, migrate, sell. I stay for support if you want, but I don't lock you in.
03
Who owns the code?
You. No licenses, no royalties, no dependency. I'm a contractor, not a SaaS vendor.
04
Can I change requirements during the project?
Yes. I work iteratively, daily commits mean a direction change costs a day, not a month.
05
How does remote collaboration work?
Slack, Linear, daily video updates. You have access to working deploy from day one.
06
Are these applications secure?
Yes. Security by design, RLS in Supabase, dependency audits, Playwright tests, best practices. I've worked for banks and a hospital, I know what compliance means.
07
Can the application be further developed?
Absolutely. The stack is Next.js + TypeScript + Supabase, an ecosystem with thousands of developers on the market. No exotic choices.
