Simon Volodin — Developer

Five years building.
I’m 21

First paid client at 16. Never stopped since — freelance, a Big Four firm, two startups, down to the low-level layer underneath.

Currently building TailorLead.

In short

Started young, went wide, and kept the depth most people trade for speed. No single credential here is the point — the range is. What follows is the long version.

Paid clients, real stakes — newest first.

TailorLeadtailorlead.io

B2B intelligence on European SMEs — search, analysis, monitoring. Goes after the European long tail that PitchBook and Bureau van Dijk under-cover.

Business-development research in finance: ~2 weeks→an afternoon.

Built a large part of it: front, back, data pipeline, AI, landing page. An agentic DeepSearch pipeline on Mastra, live conversation tracking, an internal CRM.

In pilot with top-tier European investment-banking and private-banking teams. Pitched at VivaTech 2026 and Station F; came through HEC Launchpad.

MediFlow

Founded it.

Real-time coordination for hospital operating rooms — turning surgical-emergency chaos into automated orchestration of teams and patients.

Built it full-stack and ran the DevOps — plus the client acquisition, 30+ hospital interviews, and a team of 4.

Deliberately sunset to go all-in on TailorLead.

Ernst & Young

An AI-powered audit engine, built inside the firm.

Won the internal EY hackathon — it became a paid mission.

EarlierRight hand to the CTO at MetaCard / GiftAsso — owned the entire technical scope end to end. Before that, freelancing for businesses in Nice — full project lifecycle, on time and on budget.

StudyingÉcole 42 Paris — systems, C/C++, top 3%. · M2 LEAD, Paris-Saclay — a 360° startup training: legal, finance, operations, team.

What I do

“I have taste.”

Product & UX/UIInterfaces people use without noticing them.

“I know how Netflix reaches you at 2 a.m.”

Low-level & networksC/C++, systems, the École 42 way — the unglamorous layer everything stands on, down to a self-hosted homelab.

“I make the model do the boring part.”

Agentic AIAgent pipelines, RAG, eval loops. Built an autonomous DeepSearch on Mastra.

“I take it from zero to production.”

Full-stack & infraFront, back, data, DevOps, security — the whole pipeline, nothing handed off as a black box.

“I’ve pitched it, sold it, led the team.”

Team & go-to-marketCustomer discovery, hiring, pitching to win the room — I’ve run the non-engineering half too.

“I win when it’s timed.”

Under pressureShipping something real under a clock is its own skill — the hackathon wins keep proving it.

Off the clock

The same all-in when no one’s paying me to be. 50K+ trail ultras, a regional chess title at eleven, and more philosophy than is strictly useful — the range isn’t only professional.

The other ledger →

I’m early, and I don’t pretend to have it figured out. I’ve just refused to stop building. Every year stacks another layer the last one couldn’t reach — the base is unusually deep for where I am, and it compounds. I want to put it somewhere that moves fast, around people better than me, at the edge of what’s being built.
