About

I've spent 10+ years turning broken business operations into working systems — from PwC consulting floors to building my own products in railway logistics. Based in Almaty, building infrastructure for industries that move real things across real borders.

System Design

Translating messy business logic into clean, scalable architectures.

Strategy

Market analysis, financial modeling, operational restructuring.

Execution

Ship fast, iterate, maintain. From concept to production.

Product

End-to-end builds — from zero to revenue, idea to paying users.

Case Study

RailClerk Live

Railway logistics platform that replaced Excel chaos with a single operating system for wagon fleet management across Kazakhstan and CIS. One platform, one source of truth — from movement tracking to supplier billing.

The Problem

01 Wagon movements tracked across dozens of conflicting Excel files

02 Manual day-counting for rental billing — errors led to supplier disputes

03 No audit trail — confirmed costs could be silently modified

04 Zero visibility into per-ride profitability across multiple suppliers

What I Built

Movement Engine

Async Excel ETL pipeline. Upload daily wagon data, auto-parse columns, resolve station codes, link movements to rides.

Batch Creator

Auto-groups wagon journeys from loaded to empty. Real batches from movements + synthetic batches for transit-only scenarios.

Day Counting Engine

450+ lines of billing logic. Rental days respecting loan periods, subtracting repair windows, monthly rate breakdowns.

Cost Aggregation

Unified supplier fees across wagon rental, local transit, international transit, and auxiliary services.

Confirmation Lock

Ride confirmation creates audit snapshots, locks linked costs, logs every blocked mutation. Director-only reversal.

RBAC + Multi-Tenant

Director / Supervisor / Specialist hierarchy. Financial visibility rules filter data at query level per role.
