Systems trusted with
money and load.

Payment platforms, distributed systems, DevOps and AI — from architecture design to battle-tested production.

01Approach

Three directions. One responsibility for the whole system.

Not "just another developer". I own design, code, and support as a single responsibility — no "that's not my problem".

01

Payment & Fintech Systems

SBP and QR payment acceptance, multi-bank connections, 54-FZ fiscal compliance — no lost or duplicate payments.

Payments that don't lose money under load.

02

Distributed Systems & DevOps

Microservices, Kubernetes and Terraform, monitoring and fault tolerance at every layer.

Systems you can observe and control.

03

AI Engineering

Neural networks into products: chatbots and agents, auto-content moderation, local models for privacy.

AI where it saves hours and money — not just hype.

One person instead of a team at launch — from architecture to working product.

02Selected projects

Systems shipped to production.

Not pet projects — real production systems. Clients are under NDA, so no logos, but the metrics and stack are real. Click a project to expand.

Payment core for transit fare collection: charges, refunds, fiscalization — no losses under peak load.

Tailored to your project, not to a price list.

I take full ownership — fixed price or retainer with SLA.

A

End-to-End Payment Integration

SBP and QR payment acceptance, bank connections, fiscal compliance. Payments that hold load and never get lost.

B

DevOps / Infrastructure as a Service

Kubernetes and Terraform, auto-deploy and monitoring. Infrastructure you can see and trust.

C

Custom System / ERP

From database to working product in production. I take full ownership — no "that's not my zone".

D

AI Automation

Chatbots, AI agents, content auto-moderation. I integrate AI where it truly saves time and money — not just for hype.

05 About

Albert, senior engineer
and system architect.

I've been writing code since I was 13 — my first project was a game server with a forum and website. 12 years professionally: designing and shipping complex products to production — payment platforms, ERP, multi-regional SaaS, AI services, and robotics. I build the whole system: from the database and architecture to servers and production support.
