Experience
Founding Machine Learning Engineer
Climatiq
- Building a search API on top of the Climatiq carbon emission factors database. This was my main project, which I took from 0 to 1 and maintained for 3.5 years.
- The search pipeline used hybrid retrieval and reranking. The main challenge was an ever-expanding emissions activity database with a messy taxonomy. I worked on every aspect: collecting and managing user data, setting up an annotation web app, annotating data to create datasets, training and fine-tuning encoder models, benchmarking, load testing, improving speed, and deploying to a cloud service.
- Later, we moved to a multi-turn search agent built on the existing hybrid pipeline. I fine-tuned a small open-weight LLM for the agent loop using RFT and DPO.
Founding Machine Learning Engineer
Saiga
- Hybrid chat data modeling, knowledge graphs, and cloud (AWS)-based task automation and orchestration services, including NLU and OCR-based document understanding.
- The overall goal of the automation was to map user intent to the correct specification and corresponding automation, and gather all the information needed to start the automation. This included searching the knowledge base and asking the user questions through chat, as well as some dialog management.
Senior NLP Engineer
German Autolabs
- Lead NLP Engineer and part of the core team that built the automotive voice assistant called Chris — a cross-platform, multilingual, offline, mobile voice assistant.
- Set up data collection, processing, and annotation pipelines, including crowdsourcing, Natural Language Understanding (NLU), and Dialog Management for conversational data.
- Language modeling and integration of Embedded ASR. Privacy-focused, on-device generation of user-specific grammars and creation of a Knowledge Base.
- Web app-based tools for annotation, analysis, and visualization of conversational and gesture data. Designed UX for a multimodal (voice + gestures + GUI) interface.
- Led and managed the NLP team while working closely with the Mobile and Product teams.
Co-founder & CTO
Conversate
- An entrepreneurial effort to create a customizable NLP API at the London-based tech incubator Entrepreneur First.
- Worked on a collection of APIs and tools for data bootstrapping and exploratory, iterative training of NLP models in any target domain for chatbot development.
Machine Learning Intern
Gorgias
- Automated email-based customer support workflows with a ‘smart reply’ feature.
- Topic modeling, entity extraction, and classification of email data.

Summary
Senior Machine Learning Engineer with 10 years of experience building NLP, information retrieval, and conversational AI products end to end. Most recently at Climatiq, I owned a hybrid retrieval and reranking search engine over a large carbon emissions database, covering the full lifecycle: data collection and annotation tooling, encoder fine-tuning, benchmarking, load testing, latency optimization, and cloud deployment. I later evolved it into a multi-turn search agent, post-training an open-weight LLM with RFT and DPO. Before that, I led the NLP team behind an offline, multilingual, on-device automotive voice assistant, covering embedded ASR, NLU, and dialog management, and co-founded an NLP API startup as CTO.
