Experience

TSFM Researcher (Master's Thesis) - University of Amsterdam
2024 - Present
  • Researching Time Series Foundation Models (TSFMs) with a focus on the Chronos model family — pre-trained probabilistic forecasters built on language model architectures — as the core subject of the master’s thesis at UvA.
  • Applying Chronos2 to cryptocurrency price series for multi-horizon trend forecasting, evaluating zero-shot and fine-tuned performance on volatile, non-stationary financial data.
  • In-depth understanding of probabilistic forecast objectives, especially pinball (quantile) loss, with hands-on analysis of their behavior on fat-tailed distributions.
  • Investigating the transferability and fine-tuning generalization of large-scale TSFMs for forecasting cryptocurrencies such as BTC, ETH, and LTC under rapidly shifting market regimes.
Independent Quantitative Trading Developer - GeekChomolungma
2019 - Present
  • Built a real-time market data pipeline syncing order book snapshots, trades, and OHLCV streams from Binance into MongoDB (cold storage) and Redis (hot cache), forming the data infrastructure layer for all downstream strategy research.
  • Ported and adapted statistical trading strategies from TradingView Pine Script — covering momentum, volatility breakout, and candlestick pattern signals — into a live execution framework on Binance, with real-money validation.
  • Fine-tuned quantile-regression-based time series foundation models on cryptocurrency price series to capture asymmetric return distributions; constructed and backtested AI-driven alpha signals derived from predicted quantile spreads and directional probabilities.
  • Completed Optiver’s market-making training program, gaining structured exposure to delta-neutral positioning, and bid-ask spread management.
Core Developer - Lava
Nov 2018 - Dec 2020
  • Led the full lifecycle development of Lava, a proof-of-capacity (PoC) based cryptocurrency forked from Bitcoin Core.
  • Architected and implemented consensus modifications to support PoC mining, enhancing energy efficiency compared to PoW.
  • Oversaw system integration, wallet and miner tools, and network bootstrapping.
Senior Software Engineer - Mavenir
Feb 2021 - June 2024
  • Led the High-Availability (HA) system design and development of Mavenir’s distributed element control platform, ensuring robust uptime and fault tolerance.
  • Focused on telecom-grade reliability, implementing failover, state recovery, and multi-node synchronization.

Projects

AI for Financial Time Series

Chronos2 Crypto Forecasting
Chronos2 TSFM Quantile Forecasting
Chronos2 Crypto Forecasting
Fine-tuning and applying Chronos2, a time-series foundation model, to cryptocurrency price forecasting. The project explores probabilistic multi-horizon prediction on volatile crypto data, with the BTC chart shown here as an illustrative output that changes with training mode, data window, and evaluation setup.
Risk-Calibrated Crypto Signal Framework
Custom Loss Hawkes Process Backtesting
Risk-Calibrated Crypto Signal Framework
Master's thesis project that extends the forecasting pipeline into a trading-signal and backtesting framework. It combines custom loss design for quantile prediction with Hawkes-process market risk modeling, then uses risk-adjusted expected return as a timing signal. The full thesis is linked in the Articles section below.

Crypto Trading Infrastructure

ChomoSyncer
C++ Redis/MongoDB Binance API
ChomoSyncer
A high-performance Binance market data synchronizer that streams multi-symbol cryptocurrency Kline data in real time, distributes updates through Redis Streams, and persists historical data into MongoDB for research, backtesting, and downstream trading systems.
Binance Orderbook Visualizer
Python Binance WebSocket
Binance Orderbook Visualizer
A real-time 3D visualization app for Binance order books, using streaming depth data to reveal market microstructure, liquidity shifts, best bid/ask trajectories, and transient order-book imbalances.
Kline Preprocess
OHLCV TA
Kline Preprocess
A cryptocurrency K-line preprocessing pipeline that standardizes Binance OHLCV data and generates no-lookahead technical indicator features for downstream consumers such as traditional price-volume models and time-series AI foundation models.
