Where I’ve worked, built and studied

Division 01

Product Engineering

A product engineer who owns features end to end — from user discovery and data modeling to shipping, measuring and iterating. Two products taken from zero to real users, solo.

  1. 01DiscoverTalk to users, map the workflow, find the real problem before writing code.
  2. 02Scope & designTurn findings into requirements, data models, API contracts and user flows.
  3. 03Build & shipFull-stack implementation, integrations and deploys — with AI coding tools in the loop.
  4. 04Measure & iterateInstrument, read the results honestly, fold feedback into the next release.

Shipped products

  • Put the reward lifecycle in Postgres: owed on hire, held through a cliff, released by the employer
  • Twenty-nine tables, row-level security on every one, 152 policies between them
  • Owned it end to end: discovery, data model, build, deploy, support and go-to-market
  • Next.js
  • Supabase
  • Postgres RLS
  • Playwright

Bloom

CTO & sole engineer. The community's own platform, in Russian: a feed, courses, events, messaging and an admin console, on a schema where every table is closed by row-level security.

  • Thirty screens: feed, courses, events, diary, messaging, notifications and an admin console
  • Twenty-five Postgres tables, row-level security on every one, 137 policies between them
  • Web push built from the specifications up, with a service worker and an offline page
  • Russian throughout, and every hour shown in the reader's own time zone

AI systems I built

GTM lead-sourcing agent

Details →

A scheduled AI agent that pulls leads from several sources, normalizes them into one record shape and dedupes against company, domain and contact history — output ready to send, not ready to clean.

  • AI agent
  • Scheduled jobs
  • Data normalization
  • Dedup

LLM résumé extraction pipeline

Details →

Schema-constrained LLM extraction behind an idempotent API: unstructured documents in, validated typed records out, with retries that never duplicate and failures captured for review.

  • LLM structured output
  • API design
  • Idempotency
  • Validation

Immigration CRM · 2024–2025

Sales Representative

Owned the full sales cycle on a small seed-stage team building a pizza-making robot — from first call to paid invoice.

  • Qualified inbound leads by phone and ran discovery to understand each buyer’s needs
  • Explained and demoed the product, handled objections and negotiated terms

I’ve sold it, onboarded it, supported it — and built it. So when a customer describes a gap, I can turn it into a reproducible case, a specific requirement, a prioritized ask.

Division 03

Operations & Management

Before software: five-plus years in a hard hat on Chevron sites — where the habit of hunting for the part of a workflow that shouldn’t be manual came from.

Founder · Kazakhstan

Fleet operation for a Chevron contractor

Built a 24/7 transport operation serving Chevron personnel from the ground up — around 100 vehicles, a team of about 100 and roughly $2M a year in revenue at peak. Logged 2M km with zero incidents, rolled out a company-wide fleet-management system, and served as primary point of contact for the contract, managing executives, partners and vendors.
