Clearco is a revenue-based financing platform that provides non-dilutive capital to thousands of e-commerce and SaaS businesses, using data-driven underwriting models.

• Built an LLM-based document extraction pipeline (Ollama, Phi-4, Docling, Vertex AI), reducing client document processing from days of manual review to minutes of automated extraction

• Migrated revenue forecasting for thousands of businesses from daily to weekly cadence, cutting compute time by 14% while preserving forecasting accuracy

• Implemented an uncertainty quantification framework using conformal prediction, replacing point-in-time forecasts with calibrated uncertainty bands to flag worst-performing forecasts

• Drove the analytical decision on launching a new banking-data-based financing product, providing the modelling that compared it against the existing revenue-based offering

• Diagnosed and eliminated a recurring timeout issue in the production forecasting system, removing a long-standing source of failed runs

• Designed an end-to-end automated ETL pipeline (Snowflake, Airflow, Cloud Composer) to generate datasets for forecasting research at scale

• Built a Streamlit-based annotation and metrics suite to evaluate LLM extraction quality across iterations

Zixen Trading is a high-frequency crypto trading venture co-founded with former Transfero colleagues to develop systematic trading strategies on digital assets.

• Co-founded the company and shaped its initial technical direction in systematic crypto trading

• Built the PnL tracking infrastructure that connected to multiple crypto exchange accounts and ingested live market data

• Developed the data layer used by trading strategies for backtesting and live execution

• Owned the full ML and data engineering stack as a founding technical lead during the build phase

• Designed and developed the data ETL pipeline to compute massive financial datasets, reducing computation time from several days to hours (PySpark - Databricks - Azure);
• Created a ”methodology on code” to guide new Machine Learning projects development, from which two projects were structured;
• Developed Machine Learning Models for forecasting Bitcoin Trading Volume (XGBoost, 65% accuracy) and Crypto Volatility (Temporal Fusion Transformer, 95% accuracy);
• Developed an MLOps pipeline to put models to production: calculation of hundreds of features, streaming inferences in real-time using FastAPI Websocket server, model monitoring using SQL database and Slack API (Docker on ECS, AWS FeatureStore, FastAPI, SQL, Slack), with an uptime of over 99%;
• Created a numerical Index to score Time Series data and help build trading strategies (statistical correlations, co-integration, ACE score, time series analysis).
