I design and engineer booking, search and growth systems for modern service businesses.
From marketplace search engines and appointment systems to AI assistants and marketing automation. I build digital infrastructure that helps local businesses grow.
Built with you, not billed at you
I design and engineer booking, search and growth systems for service businesses — salons, clinics, studios and the platforms that serve them. Not a template with your logo on it: a system shaped around how your business actually takes bookings, answers clients and gets found.
We start from the request
You describe what you need. I turn it into a written proposal with scope, milestones and a price — before any work begins, and before any subscription starts.
It is built in phases
Each phase is agreed, accepted and only then built. You follow progress, comment on milestones and approve new work in your own dashboard — nothing is added silently.
It keeps growing
The system is not finished on launch day. New work becomes a new phase, and the subscription grows with it — gradually, at the pace the business actually needs.
You don't pay for the project up front
The build is co-financed: instead of one large invoice, you pay a monthly subscription that starts the month after you accept the proposal. It covers continued development, maintenance, domain, hosting and everything listed under Services — for as long as we work together.
Website

A presence that is found, not just built.
Presentation sites, portfolios, landing pages
WebApp

Workspace
$299/ month
The whole operation in one place.
Multi-user teams, internal processes, integrations
Growth
$549/ month
Ongoing engineering, search and conversion work.
Platforms that grow month over month
Which tier applies depends on the scope agreed in your proposal, and it can move as the system grows — a project often starts small and steps up only when there is more to run. Send a request and you'll get a written proposal with the exact scope and price.
Code review that reads the architecture, not just the syntax
Most AI code review tools give you superficial linter remarks. I offer something completely different: elite architectural, security and QA review of the code in your repository — AI agents do the deep analysis, and I personally control, test and verify every pull request.
You don't just get typos fixed. You get a guarantee that the system holds at the level of architecture, security and performance — specialised agents, a diagnostics engine and deep research do the analysis, and every finding then goes through my own verification, where I validate the proposal, test the edge cases and make sure the refactored code still fits your business model.
All I need is access to your remote repository on GitHub or GitLab. There is no documentation to write for me — the agents map the structure, modules, dependencies and business logic themselves, across React, Node / Express, PHP / Laravel, Python / FastAPI, Postgres and MongoDB, down to auth, CI/CD and the notification layer.
Starter Plan
$19/ month
Ideal for smaller projects, solopreneurs and early-stage startups.
AI volume: 160 messages or 5M tokens per month
What you get from the AI agents
- Automatic PR review of basic changes on main / dev branches.
- Detection of syntax errors, types (TypeScript / Pydantic) and potential bugs in Express and FastAPI routes.
- Checks for basic security vulnerabilities — raw queries, JWT structure.
What you get from my control
- Validation of the AI findings and a short QA report for every reviewed PR.
- A check that the fixes follow good practice for the React / Node or Python stack.
Pro Plan
$49/ month
For teams and growing products that need fast delivery without losing quality.
AI volume: 500 messages or 15M tokens per month
What you get from the AI agents
- In-depth architectural analysis of entire modules, up to 200k of context.
- Automatic N+1 query detection (Postgres joinedload / Mongo $lookup) and async event-loop blocking detection in FastAPI.
- Ready-to-use refactored code proposals on GitHub pull requests, in real time.
- CI/CD pipeline integration (GitHub Actions) for continuous review.
What you get from my control
- Architectural review of how services and databases relate to each other.
- Checks on edge-case scenarios, race conditions and data consistency under load.
- Advice on design patterns and error-handling strategy.
Extraordinary Plan
$249/ month
Full guarantee and commitment for scalable systems, enterprise and complex monorepo / microservice architectures.
AI volume: Unlimited
What you get from the AI agents
- Continuous deep research and auto-monitoring of your repository, 24/7.
- Complete penetration and security check — OAuth2 flows, RBAC / scope validation, Pydantic and Mongoose edge cases.
- Full AI integration into your CI/CD pipeline, with dedicated agents automating testing and refactoring.
- Refactoring proposals for complicated functions at senior / architect level.
What you get from my control
- An elite architect, security expert and senior QA engineer working directly inside your team.
- Full understanding and protection of your business model through the code.
- A detailed technical walkthrough of every segment: React frontend, Node / Python API, coupled databases (Postgres + MongoDB).
And on top of that
- Priority support and direct consultation on architecture and scaling.
