Evgeny Goncharov — Technical Advisor, Madrid

The advisor

I'm Evgeny. I build internal systems.

Madrid-based, independent since 2018.

Identity migrations to Auth0 — multi-tenant, zero-downtime, SSO across legacy and new estate. PDF→Excel automation for documents that won't surrender to Tabula or Camelot — OCR plus layout heuristics plus per-template extraction. Slack bots with custom modal flows, threaded review queues, attachment handling, and multi-tenant state — not chat-completion wrappers. Shared codebases across 11 native iOS/macOS apps on a single Swift package. Hand-built marketing sites that ship green on Lighthouse without a CMS.

Fixed price, two weeks, full code ownership. No per-seat licensing, no retainer, no SaaS lock-in. A 20-minute discovery call comes first — if there's nothing worth building, you keep the call and the notes.

Currently advising a Madrid wealth management firm on the operational workflows that quietly consume senior partner time.
