AleksandrChernikov

A Generator is a scheduling engine sold as an API. We start with schools: school software calls our API to build the timetable and find substitutes; schools without such software use Vyorm Schedule, our web app on the same engine. The engine has new best-known results on 4 of 25 instances of XHSTT-2014, the international school timetabling benchmark, and 4 new best-known solutions in nurse rostering. I write all of the code, with Claude Code. I also run Alrevion, my product studio in Tashkent.

Experience

A Generator is my company. Alrevion is my product studio in Tashkent.

Founder & CEO, A Generator

A scheduling engine sold as an API; I write all of the code, with Claude Code.

  • Engine. Our own Rust core of about 75,000 lines, written from scratch. For a real school (1,711 lessons in its weekly timetable) it builds a complete clash-free timetable in 3.5 s once the data is in; it measures how close each timetable is to the best possible and explains when a task has no solution.
  • Product. The API has been live since 29 October 2026: school software calls it to build the timetable and find substitutes. Schools without such software use Vyorm Schedule, our web app on the same engine (a demo in testing).
  • Benchmarks. New best-known results on 4 of 25 XHSTT-2014 instances, verified with the official HSEval evaluator, submitted to the XHSTT archive, not yet published; 4 new best-known solutions and 6 new lower bounds in nurse rostering, accepted by schedulingbenchmarks.org (details below).
  • Roadmap. Schools, then universities, then hospital and shift rostering, then vehicle routing.

Founder, Alrevion

My product studio in Tashkent: 12 products built, 5 launched to real users; fixed-price and hourly work for local clients.

  • Shared platform. Alrevion Auth (OTP, password + TOTP 2FA, passkeys / WebAuthn, social sign-in; JWT / JWKS) and Alrevion Push (Web Push, APNs, FCM; scheduling, retries, signed webhooks) — one identity and notification layer for every product, edge-native on Cloudflare Workers.
  • Delivery. Specification and plan before code (domain model, constraint catalog, ADRs), weekly working increments, acceptance through independent verification; clients assemble the scope in an interactive estimator with a live price and timeline (three-point estimates with risk reserves); AI-native workflow with coding agents and adversarial review; pre-seed pitch deck and financial model.

Independent Business Consultant

Freelance · manufacturing and services SMEs

  • Restructured the sales funnel at a company that manufactures refrigeration equipment; pricing and targeting changes led to an increase in monthly revenue of at least 20% within 3 months.
  • Implemented a CRM system and task automation at a service company; this reduced manual work and cut client response times by about a third.
  • Modeled AS-IS processes, found automation opportunities and prepared requirements and a digital-infrastructure roadmap for owners and managers.

A Generator

My company. The engine builds the timetable and measures its quality.

A scheduling engine sold as an API

Lessons, rooms, teacher workloads and health rules go in; a clash-free timetable with a measured quality score comes out. We start with schools: school software calls our API to build the timetable and find substitutes, and schools without such software use Vyorm Schedule. Next come universities, then hospital and shift rostering, then vehicle routing. The engine runs on our own Rust core, about 75,000 lines written from scratch: it measures how close each timetable is to the best possible and explains when a task has no solution.

Soft-constraint penalty, lower is better; 0 hard-constraint violations. Previous bests: GOAL, 17 April 2017 (XHSTT archive). Our solutions are verified with the official HSEval evaluator and were submitted to the XHSTT archive on 14 and 28 October 2026; not yet published. Our scores match HSEval on all of the benchmark’s 25 problems from real schools in 12 countries. Solution files are available on request.

Plus 6 new lower bounds, accepted on 27 October 2026; all on the site’s original nurse rostering instances, listed on the benchmark changes page. Our reading: for ERMGH-A and ERMGH-B the new lower bounds meet the best-known solutions, so those are optimal.

Idea → Delivery

How I take a product from an idea to a working system.

From idea to MVP and delivery

my own method

This is how I run products myself. Every stage ends with a question, an artifact and a decision: continue, stop, hold, or change the hypothesis. The rule is to learn cheaply whether to go on — a conversation first, then a prototype, then a prepayment, and only then code. I also wrote the method down as a skill for AI agents, so the same process and templates run on every project.
