Founder, CTO, principal engineer

Business platforms for real operations.

I build business systems for transportation, reservations, pricing, dispatch, partners, payments, and AI-assisted operations. My work sits where architecture and daily operations have to stay aligned.

Operator mindset, engineering depth.

I am not just building pages around a business. I build the operating layer behind the business: the data model, the workflows, the pricing logic, the portals, the integrations, the payment flow, and the tooling that lets people actually run the company.

My strongest work is in complex business platforms where software has to reflect real-world constraints: traveler intent, trip details, vehicle classes, providers, agencies, corporate accounts, billing, statements, approvals, exceptions, and operational follow-up.

I work across product direction, architecture, backend systems, database design, user-facing flows, internal tools, release execution, production troubleshooting, and long-term platform evolution.

Business first Every technical decision is tied to how the business sells, fulfills, charges, supports, and scales.
Production ownership I stay close to the system after launch, including edge cases, support findings, data repair, and operational feedback.
Systems over fragments The useful work is connecting the public experience, internal operations, partner workflows, data integrity, and automation.

Platforms with business weight behind them.

These projects span transportation aggregation, reservation and operations ecosystems, group travel infrastructure, service-business platforms, and a direct-to-consumer business I built and operated in Ukraine.

Ground transportation

Azeum

Co-Founder and Chief Technology Officer

Azeum is a ground-transportation aggregator designed around private transfers, airport rides, hourly service, city-to-city trips, corporate travel, travel agencies, providers, and partner distribution.

I own the product and platform architecture: booking sessions, vehicle catalog, provider inventory, rate and region tooling, traveler and partner workflows, management portals, localization, transactional messaging, and payment-ready reservation paths.

  • Reservation and quote lifecycle
  • Provider portals and rate imports
  • Travel agency and corporate flows
  • Payments and transactional email
Reservations and operations

BookALimo

Lead Software Engineer and Platform Architect

BookALimo is a reservation and operations ecosystem for limousine and chauffeur service. The work spans public booking, customer accounts, corporate accounts, travel agencies, affiliates, providers, dispatch support, billing, statements, notifications, and partner APIs.

I took ownership of a major platform rewrite and built the domains that connect booking, pricing, dispatch, provider handoff, account management, payments, documents, reports, production operations, and AI-assisted reservation workflows.

  • Booking, quotes, dispatch, and tracking
  • Affiliate, provider, and account workflows
  • Pricing engines and business exceptions
  • Billing, statements, documents, and APIs
Group travel

Book A Motorcoach

Platform architecture and implementation

Book A Motorcoach is focused on motorcoach and group transportation: hourly trips, multi-passenger planning, coach selection, city landing pages, branded booking flows, travel-account workflows, and reservation visibility for operations teams.

The platform work is built around the realities of group transportation, where quoting, timing, vehicle capacity, route complexity, and operational communication need a different level of structure than a simple contact form can provide.

  • Motorcoach booking and quote flows
  • Hourly and group trip handling
  • City pages and service visibility
  • Branded emails and account workflows
Service business operations

Metro Surface Solutions

Co-Founder and Technical Partner

Metro Surface Solutions is an exterior surface services company. My role is the business and platform layer: turning a service operation into a repeatable system for quote intake, pricing, review, customer records, crew workflows, payments, and follow-up.

I built the public site and the operating platform behind it: multi-service estimate requests, DB-backed pricebook, coverage checks, project photos, manual review, customer and management portals, payment requests, checkout, webhooks, and transactional communication.

  • Quote intake and instant estimates
  • Pricebook and coverage logic
  • Customer, crew, and management portals
  • Payment requests and operational follow-up
Direct-to-consumer ecommerce

Small Food

Founder, product owner, and full-stack developer · 2021–2022

Small Food was a Ukrainian ecommerce business selling microgreen growing kits, seeds, and supplies. I built the ASP.NET storefront and operating system from scratch, then ran product, merchandising, fulfillment, customer service, and the day-to-day business.

The business was gaining traction until Russia's full-scale invasion of Ukraine caused demand and day-to-day operations to collapse. I closed Small Food in 2022, and I may revive it when the situation in Ukraine becomes stable enough for the business to operate again.

  • ASP.NET ecommerce platform
  • Catalog, pricing, and order workflows
  • Customer service and fulfillment
  • End-to-end business ownership

What I bring to a business.

The value is not a list of libraries. It is the ability to understand a messy operation, model it correctly, ship the software, and keep improving it under real production pressure.

01

Business software architecture

Turning reservations, service scopes, partners, providers, accounts, payments, and support workflows into coherent production systems.

02

Transportation domain modeling

Point-to-point and hourly trips, stops, wait time, luggage, passengers, vehicle matching, airport context, providers, dispatch, and edge cases.

03

Pricing and quote engines

Rate regions, distance, time, vehicle class, add-ons, tolls, provider rules, account rules, overrides, exceptions, and review workflows.

04

Payments and communications

Checkout, payment requests, webhooks, authorizations, receipts, transactional email, documents, statements, notifications, and follow-up.

05

Portals and operating tools

Public flows, customer accounts, partner portals, provider tools, management surfaces, internal dashboards, and release-ready workflows.

06

AI-assisted workflows

Assistant behavior embedded into reservation and operating systems, connected to account context, controlled actions, production data, and business rules.

For transportation, travel, and service-business conversations.

If you are evaluating a partner, a platform, a travel workflow, or a business system, email is the cleanest place to start.
