Many businesses still depend on spreadsheets, copy-paste and fragile one-off scripts. I design and build robust Python tools tailored to the way you work: data-processing engines, connectors between systems, command-line utilities, small internal web apps and APIs.
Each tool is readable, documented and tested — written to be maintained, not just to work once.
Why it matters
Off-the-shelf software rarely fits a specific workflow perfectly. A well-built custom tool closes that gap: it does exactly what you need, integrates with the systems you already have and grows with your business.
Years in capital markets, where data quality is non-negotiable, taught me a simple discipline that I apply to every tool: validate the inputs, log what happens, and fail loudly rather than silently.
What you can expect
- A clear spec of what the tool will do, agreed before development starts
- Data processing with pandas, SQL databases, Excel/CSV files and APIs
- Connectors and integrations between the systems you already use
- Clean, tested and documented code that you fully own
- Packaging and deployment on your machines, server or cloud
- Support after delivery, and evolutions as your needs grow
