Services

Python tools for repetitive business workflows.

Automation & Data

Small Python workflows that turn repetitive file and data tasks into repeatable outputs.

  • Python automation
  • CSV/Excel processing
  • Cleaning and validation
  • Reporting

APIs & Backend

Practical services that receive data, apply business rules, and pass useful results to the next step.

  • REST APIs
  • Webhook workflows
  • FastAPI/Flask utilities
  • API-to-file/data workflows

Web Scraping & Extraction

Public web data collection with structured outputs that are ready to review or reuse.

  • Public data extraction
  • HTTP/browser automation
  • CSV/Excel outputs
  • Change monitoring when appropriate

Projects

Projects with real outputs.

Each project links to its public source and shows output produced by the project itself.

About

How I Work

I build small Python tools for repetitive, testable business workflows.

I focus on automation scripts, spreadsheet workflows, API integrations, public-data extraction, and lightweight backend utilities.

I prefer solutions with clear inputs, clear outputs, and results that can be tested before delivery.
