Former GETCO, Geneva Trading, Auros Global, and Epoch Americas engineer building trading systems, broker integrations, market-data infrastructure, execution automation, and quantitative tooling.
I help traders, funds, and technical founders build or repair systems where reliability, execution correctness, and data quality matter.
My background is in trading infrastructure and quantitative systems at GETCO, Geneva Trading, Auros Global, and Epoch Americas. That work required software that could be tested, monitored, explained, and trusted when real money and real operations were at stake.
Today I help traders, funds, founders, and operating teams build or repair systems where the failure mode is not “we need more code.” It is bad data, fragmented workflows, unreliable integrations, unclear ownership, weak controls, or no record of what actually happened.
Common projects:
• Trading bots and execution systems
• Broker and exchange API integrations
• TradingView automation
• Market-data pipelines
• Backtesting and strategy validation
• Risk controls, order-state tracking, and position reconciliation
• CRM / client-data workflows
• API integrations and workflow automation
• Internal tools, dashboards, and operational reporting
• Evidence-gated systems that separate what works today from what still needs to be built
Recent work includes automated execution systems, DAS Trader-style risk automation, async fill handling, pre-trade risk controls, market-data infrastructure, backtesting frameworks, client-data workflows, and production API/worker systems.
Relevant proof:
• Production trading engine: single-writer order registry, idempotent fill handling, stale-fill rejection, and non-blocking async execution
• Quant research/backtesting framework independently audited A− / 92/100
• Market-data/API platform with ~68.6K lines of code, 1,230+ tests, 13 shipped products, and 42 API endpoints
• Systems with clear testing, validation, documentation, and handoff boundaries.
I work best with clients who need a system that is understandable, testable, monitored, and safe to operate—not just something that runs once.
I do not sell strategies, promise returns, or provide investment advice. I build the infrastructure, tests, controls, documentation, and execution paths needed to evaluate and operate workflows more reliably.
Send me what you are building, which systems need to connect, where the workflow is breaking, and whether you already have code. I will tell you the cleanest path to test it, fix it, or get it into production.

Senior Software Developer and Industrial ML Specialist with over 20 years of experience. In my previous role I built mission critical software, including the control systems (SCADA) used to run pipelines, LRT systems, and power plants. Since then I co-founded a startup to build the ML to augment those systems, optimizing industrial systems to reduce power cost and increase throughput, and building failure prediction and detection systems to avoid costly downtime and repairs.
My industrial background gives me the experience needed to take software past "production ready" to the five-nine reliability needed when a single glitch can take down a multi-billion dollar production system, or prevent life-saving infrastructure from running in an emergency.
As an ML engineer I went back to those same systems with an eye towards the hidden opportunities buried in the raw data. This involved dealing with the complexities of messy real world data such as: missing or malfunctioning instruments, unknown time offsets, unlabelled data, missing logs, and clients with a very different view of the systems. I handled the full lifecycle: data validation and cleaning, feature engineering, model development, application design, and cloud deployment.
As a developer I specialize in C/C++, Python, and JavaScript, and am a skilled full-stack developer with strong Linux/Unix system administration skills. My ML specializes in time series, regression, and categorization, but I have built solutions in many other areas including Computer Vision, Reinforcement Learning, and Large Language Models.
Having co-founded and led a startup I have a strong eye for evaluating business proposals and focusing on what's needed for a successful MVP. For instance, I know when a particular piece of functionally is critical to the value proposition, and thus needs to be absolutely flawless. And I know which bits of functionality just need to be done as quickly and cheaply as possible so the prototype can get out the door.
