Project details

Spending hours every week cleaning spreadsheets, merging exports, or copying numbers into reports? I build Python scripts that do it in seconds.

I automate data processing workflows with Python (pandas, openpyxl): cleaning and deduplicating messy files, merging multiple sources (Excel, CSV, PDF, system exports, APIs), validating data, and generating ready-to-use outputs, clean files, database records, or formatted Excel/PDF reports.

What you get: a working script tested on your real files, the source code so you own it, and documentation on how to run and modify it.

Real experience: I build data pipelines professionally in the telecom industry, processing thousands of records daily from a corporate data warehouse into reports and dashboards used by commercial teams every day.

About Jhonatan

Jhonatan I.Status: Offline
Python & n8n Automation | AI Chatbots & Agents | Dashboards & APIs
Villa Elisa, Paraguay - 6:53 pm local time
Do you spend hours manually pulling data from different systems, building reports in Excel, or maintaining dashboards that keep breaking? I automate that.
I build Python automation pipelines, n8n workflows, interactive dashboards, and AI assistants that turn hours of manual work into minutes.

What I bring:
- Automation and integrations: Python, n8n, REST APIs, web scraping (Playwright/Puppeteer), AI agents
- Data and dashboards: ETL pipelines, PostgreSQL, Power BI, geospatial (GeoJSON)
- Full-stack: FastAPI backends, React/TypeScript frontends
- Legacy modernization: I add modern React UIs inside existing Laravel/PHP or legacy portals without a rewrite and without downtime

Real experience:
- At Tigo Paraguay (telecom) I built the internal data platform used daily by commercial teams: an automated Python ETL that processes 5,000+ network nodes and publishes to an interactive map and dashboards in a cycle of minutes.
- I co-founded a healthcare platform and built its full stack from scratch: clinical records, scheduling, statistics, and an AI WhatsApp assistant (n8n, Supabase, GPT).
- I built and open-sourced Midden, an OSINT and web-scraping tool in Python (public on my GitHub).
- I automated bulk invoice loading on a government tax portal with Playwright (RPA), resilient to interface changes.
If you have a repetitive process, a messy data workflow, or a tool that keeps breaking, tell me what you are dealing with and I will show you how I would automate it. I respond fast and communicate clearly.
