Fedor Gofman
Full‑stack
developer.
ERP & AI.
I take products from zero to real production use: manufacturing ERP systems, voice AI assistants, integrations at the protocol level rather than just REST API. 6+ years in development.

01 / About
I specialize in taking a product from zero to real production use — I designed and single-handedly shipped several ERP systems for manufacturing companies: architecture, database, role-based access, warehouse and production accounting. These systems now run in production at clients; they didn't stay pilots.
A separate focus is AI integrations: voice assistants built on Yandex SpeechKit Realtime + Asterisk telephony, dialog-analysis pipelines with LLM scoring. I also have experience with less typical tasks — for example, implementing the TonConnect protocol by hand (decrypting bridge messages via NaCl), which requires working a level below the usual REST API.
I actively use AI coding agents (Claude Code) as my main development tool — I assign tasks, review the diff, require tests. I prefer to understand the business process before writing code.

02.2026 — present
01
Ivolga
Full-stack Developer (AI integrations, ERP systems)
- — Designed and built 2 independent manufacturing ERP systems (woodworking, steel structures): role-based access (up to 7 roles), a multi-stage production cycle from order to shipping, warehouse accounting
- — In-app docx/xlsx editing integrated via OnlyOffice Document Server
- — Self-hosted infrastructure on Supabase (PostgreSQL + PostgREST + Auth + Storage + Edge Functions), multi-tenancy
- — Both systems shipped and put into production use at clients
- — A line of voice AI assistants (IVR) for three business verticals (tire service, pawnshop, tech support): Yandex SpeechKit Realtime + Asterisk telephony (AudioSocket/ARI), automated appointment booking, reserving stock in the warehouse, CRM (Bitrix24) and mapping-service (Yandex Maps) integration
- — A dialog-analysis system for retail: speech recognition (Whisper / Yandex SpeechKit) → speaker diarization (pyannote.audio) → LLM scoring against the sales script (Ollama) → dialog-path visualization for service-quality control
- — In parallel, contributing to an AI module (an AI-agent panel with multiple LLM providers, chat, persistent history) for a cross-platform desktop app on Rust/Tauri/Vue

02
Independent project
Software Engineer (Automation / Reverse Engineering)
- — Implemented the TonConnect protocol (TON wallet connection) by hand: decrypting bridge messages between the dApp and the wallet via NaCl box decryption, recovering the secret key — reverse engineering of a closed data-transfer protocol
- — Built browser-automation clients on Playwright/Patchright for Telegram Mini Apps: client-environment emulation, network-traffic interception (including the TonConnect bridge), crypto-wallet integration (TON, Solana)
- — Integrated an anti-bot bypass system (captcha solvers: hCaptcha, reCAPTCHA, FunCaptcha, Turnstile, GeeTest)
- — Automation of web-application interaction scenarios: Python, Selenium, Node.js, JS scripting
- — Optimized the system for high load: stable parallel operation of up to 40,000 concurrent sessions/instances
02.2023 — 06.2024
03
Simex (private pension fund)
Software Engineer
- — Built a web system for generating commercial proposals for the sales department (React + Node.js): automatic docx generation, converting amounts to words
- — Developed algorithms for identifying substance composition from spectrometry data (Python): finding the closest reference spectrum
02.2021 — 02.2023
04
Independent projects
Frontend Developer / Automation Systems Developer
- — Built a blockchain dApp (WAX/EOS): React + Redux Toolkit, crypto-wallet auth, game modules (crafting, market, staking) — about a year of active development on a team
- — React frontend development for an external project (~3 months)
- — Built browser-automation systems: Python, Node.js, Selenium — automating web-application interaction scenarios
- — Reverse engineering of frontend client logic, analysis and bypass of protection against automated access (anti-bot systems, behavioral checks)
02.2020 — 02.2021
05
DataKrat-S
Developer
- — Started while at university — first an internship, then employment (~1 year)
- — Built bash scripts for automatic infrastructure deployment and updates (a homegrown CI/CD): a Node.js/Express server received GitHub webhooks and ran the deploy of the NestJS backend and frontend
- — Sole developer of a restaurant loyalty system, from scratch: database design (MongoDB), microservice architecture on NestJS (auth, menu, cart, loyalty cards, API gateway), React Native frontend
- — Integration with the r_keeper POS system: pulling the menu via the POS's native XML HTTP API, plus a custom Delphi module linked directly into the POS to accept loyalty cards
- — CRM integration (calls/deals over Asterisk telephony), parsing PDF invoices, customer face recognition
- — Delivered the full feature set: pre-order, menu loaded from the POS, loyalty program
