Technical Product Leadership

Scrum Product Owner Certified

I prioritize the roadmap, scope requirements, write specs and coordinate stakeholders. Two startups cofounded and run end-to-end (Foundingbird, Kaunto): I know what shipping looks like.

AI for Business

I help SMBs and enterprises adopt AI: RAG, semantic search, LLM integrations, workflow automation, finding the right tool without overengineering. Designed and sold a Document AI SaaS in 2025.

Solutions Architecture

Built the ingestion pipeline for 100M+ pages at L'Oréal (OCR, vectorization, semantic search). Designed relevanC's analytics platform processing 400M+ events/month.
Full-stack (React, React Native, TypeScript, Python, FastAPI) on GCP with Terraform.

What clients say

Read on LinkedIn ↗

Antonin is technically solid, but above all impact-driven. He does not just do the job: he digs into the stakes behind every topic and delivers something that actually creates value. Pragmatic, reliable and structured, he moves fast without losing sight of what matters.

Ciprian NoaghiuCEO, relevanC

Read on LinkedIn ↗

Antonin stands out for his strong pedagogical skills: despite a high level of technical expertise, he is able to explain complex topics in a clear and accessible way to non-technical stakeholders.

Paula AlvesHead of AdOps, retail media

Read on LinkedIn ↗

Where many before him failed, Anton succeeded, bringing about significant improvements in a short span. What sets him apart is his leadership, skill in stakeholder management, strategy, attention to detail and vision for the long haul.

Case studies

How I solve concrete problems, and what I can rebuild for you.

See all case studies →

Build

An autonomous research agent over a private corpus (RAG, Google ADK)

No answer ships until every part of the question is covered or marked no data found

Ask for a comparison of eight products, get a confident answer about two, with nothing saying the other six were never searched.

Read the case study →

Build

Document intelligence at scale: RAG over 100M+ pages

100M+ pages, an answer in under a second, a citation on every sentence

Thirty brands, a dozen languages, and a team redoing a study that already exists because nobody can find it.

Read the case study →

Build

A 100% local AI coding stack (Ollama, Qwen3.6, opencode)

A dozen local models benchmarked, one kept, and the code never leaves the box

The meeting ends with no AI on this codebase, and the team loses the gain instead of the risk.

Read the case study →

Automate

Output contracts for LLM-generated SQL in production

Every generated query is parsed, scoped to the asker's rights and rewritten before it touches the database

The wrong answer looks exactly like the right one, and it just read a table this user was never cleared for.
