Quant Finance & AI Infrastructure
QuantJourney was built to accelerate strategy discovery — from idea to backtest — using a flexible architecture for cross-sectional, multi-asset, and factor-based strategies.
- Supports deep AI-driven factor modeling, regime detection, and portfolio signal generation across thousands of assets — including equities, futures, crypto, and FX.
- Our proprietary Strategy Development Language (SDL) enables quants to define, validate, and optimize alphas using technical, fundamental, and macro signals — without rewriting pipelines for each new idea.
- Trusted by a few hundred clients globally, including hedge funds, family offices, and advanced quants managing $10M–$500M AUM.
"What others spend years building in fragmented stacks — we deliver in weeks, at scale, with elegance.
Clients often respond with just one word: 'Wow.'"

Corporations, Science and Startups
Worked for T-Mobile, Orange, Microsoft, Oracle EMEA in Europe and Middle-East.

- Founded 5 technology companies, with VC funding and successful exits — including one of the earliest AI startups in Central Europe, awarded Best Startup in CEE (2005).
- Delivered enterprise-grade solutions and digital architecture for:
- Microsoft (MEA Innovation Lead)
- Oracle EMEA
- France Telecom / Orange, T-Mobile, and telcos across Europe
- Dubai Government, Ministry of ICT (Qatar), and major state-backed organizations in Saudi Arabia
- Recipient of the Microsoft CEO Award for Best Marketing Campaign
- Led cross-functional global teams in high-stakes, fast-moving environments — always at the frontier of technology and innovation.
- Background in theoretical and applied physics, with early research work at CERN — where I developed the analytical mindset and systems discipline I now apply in finance and technology.
- I bring scientific precision to every layer of development — from model validation to infrastructure resilience — building systems that are explainable, testable, and robust under real-world volatility.
Quant Development & Systems Engineering
I don't just write code. I build infrastructure that rivals top quant firms.
- Architected QuantJourney with a multi-cloud, horizontally scalable architecture.
- Every client runs in a fully isolated environment — ensuring data security, compliance, and reproducibility — modeled after best practices at Tower Research and Two Sigma.
- Supports 100+ parallel backtests across 5,000+ assets, with async execution, smart scheduling, and full observability.
- Native support for multi-cloud deployments (Hetzner, AWS, GCP, Azure) and hybrid setups (on-prem + cloud) — enabling quant teams to scale flexibly.
- Designed to empower lean quant teams to operate at Citadel-scale — without Citadel-size engineering teams.
"Wow. This is world-class."
