Talent Partner + internal AI builder (GTM, DACH/EMEA)

Lucanet AG

Built an internal AI recruitment assistant (Python, LangChain, Claude API) and deployed it into the team's Greenhouse workflow: automated candidate screening, structured interview-feedback extraction from transcriptions, and comms across high-volume DACH/EMEA GTM pipelines. Scoped the need with TA/GTM leadership, shipped the tool, and drove day-to-day adoption, the same loop a forward-deployed engineer runs at a customer site.
Led ATS migration from Personio to Greenhouse across the whole team: data model, migration, and team adoption.
Ran discovery-style intake calls translating vague requests ("we need someone senior for Italy") into structured requirements, the muscle a forward-deployed engineer uses to scope a customer deployment. 80%+ offer acceptance, ~120% of quarterly targets. Discovery and delivery in EN, DE, ES, FR.

Talent & Coordination Partner

RapidAPI

Designed and shipped a company-wide interview-coordination automation spanning 180+ employees, 20+ hiring managers, and 5+ C-level executives across Germany, USA, and Tel-Aviv offices. 500+ interviews automated; scheduling friction reduced ~90%. An internal product with real users across three offices. I scoped, built, deployed, and drove its adoption without an engineering team behind me.
Full-cycle technical recruiting for backend, frontend, DevOps, and API engineers, so I am fluent in the engineering conversation.

Forward-Deployed Engineer

AgoraFinancials

Built the Pythagoras Method: 9 LLMs across 5 providers independently rate 8 financial metrics, with structured multi-round debate loops that resolve disagreements until consensus, a homegrown eval-and-consensus harness that reduces single-model bias.
Two-tier model architecture (fast models for numerical extraction, deep models with RAG tools for qualitative reasoning over SEC filings) behind a unified OpenRouter gateway.
Owned end to end and live with paying users: FastAPI, PostgreSQL + pgvector, Stripe token economy, PDF report generation, Dockerized on Railway.

Spralingua

Multi-agent architecture with specialized vocabulary, grammar, and conversation agents built on Claude's language understanding. Sub-2-second conversation loop end to end.
Full-stack Flask app with real-time speech-to-text (Web Speech API) and Minimax TTS for natural multilingual speech; serving users in 4 languages. Deployed on Railway with Gunicorn.

TubeText

Async FastAPI backend orchestrating Deepgram Nova-3 (audio to text), OpenAI GPT-4 mini via LangChain (structured summaries), and Cerebras Llama-3.3-70b (real-time translation streamed over SSE) in four languages.
Chose Deepgram over Whisper for production reliability; async SQLAlchemy with Alembic migrations; Google OAuth and Stripe billing; PDF export. A live SaaS with real users.

Summary

Forward-Deployed Engineer who ships AI products end to end and is comfortable being the technical person in the room with the customer. Three live LLM products with paying users (a multi-LLM consensus engine for financial analysis, a production transcription-and-translation SaaS), plus internal AI systems I scoped, built, and rolled out in-role at Lucanet and RapidAPI. Four years of customer- and stakeholder-facing B2B SaaS across DACH/EMEA before the pivot. I run discovery and turn vague business problems into working deployments.
