Profile Summary

I’m a research engineer and interdisciplinary technologist, with experience spanning academic research, simulation design, financial modeling, and distributed systems. I specialize in stochastic modeling, machine learning, and full-stack prototyping, and have contributed to peer-reviewed research, patented innovations, and hackathon-winning projects. I recently co-authored a simulation-based study on game-theoretic human behavior, accepted at ISAGA 2025, where I also served as a peer reviewer (currently withdrawn however to publish in journal). My technical expertise includes Python, statistical analysis (NumPy, Pandas, SciPy), Monte Carlo simulations, and Docker-based deployment. I'm actively working on Grass, a holistic credit scoring system using machine learning and the Black-Scholes-Merton model, and Atlas, a developer-friendly multichain infrastructure for decentralized applications. My background blends academic rigour with practical implementation — from building Chrome extensions for accessibility (CS50X final project) to architecting blockchain systems and conducting AWS-deployed simulations. I also hold certifications in Full Stack Development (University of Helsinki) and User Experience Design (Accenture). I'm particularly keen on remote research projects in: Computational social science Quantitative finance & credit modeling Applied game theory Blockchain & distributed systems Accessible technology
