Dávid Csontos
Quant Developer · Optimisation & Algorithms
I design and build quantitative systems: trading infrastructure, optimisation engines and the data pipelines behind them. Work with me when the maths has to be right and the software has to hold up in production.
What I do
Maths that works in practice
Mathematical optimisation
Scheduling, allocation and pricing models that find the best decision under real constraints.
Algorithmic trading
Strategy research, backtesting and execution code built for live markets.
Logistics algorithms
Routing and planning algorithms designed for real shipping operations.
Data pipelines & automation
Robust data flows from raw sources to the numbers your decisions depend on.
Cloud & monitoring
Azure deployments with Grafana monitoring, so you always see what is running.
Technical training
Workshops and mentoring in C++ and algorithms for engineering teams.
Also available
AI automation for business
The same engineering discipline, applied to everyday operations: less manual work, fewer errors, faster responses.
AI agents
LLM-based assistants that answer, research and act inside your own tools and data.
Workflow automation
Repetitive processes like reporting, data entry and document handling, automated end to end.
CRM & integrations
CRM setup and automation, connected to email, forms and the rest of your systems.
Track record
Proven under pressure
National and international competitions sharpened one skill above all: finding the right algorithm quickly and getting it right the first time.

Competition-grade algorithms
Problems that look intractable usually have a known structure underneath. Finding it is what I do.
Live trading experience
Strategies, infrastructure and monitoring that have run against real energy markets.
Clear communication
Technical trade-offs explained in plain language, to engineers and management alike.
