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.

01About

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.

Fig. 01The operating layer behind the business

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.

  1. 01

    Business first

    Every technical decision is tied to how the business sells, fulfills, charges, supports, and scales.

  2. 02

    Production ownership

    I stay close to the system after launch, including edge cases, support findings, data repair, and operational feedback.

  3. 03

    Systems over fragments

    The useful work is connecting the public experience, internal operations, partner workflows, data integrity, and automation.

02Selected projects

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.

BookALimo

Lead Software Engineer and Platform Architect

Group travel 03/05

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

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

Direct-to-consumer ecommerce 05/05

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

03Capabilities

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.

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

  2. 02

    Transportation domain modeling

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

  3. 03

    Pricing and quote engines

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

  4. 04

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