Backend & Integration Engineer Tunja, Colombia · Remote

I connect systems, build internal tools and trace production incidents through code and data. Over three years with Python/Django, NestJS, Laravel, Java and SQL.

Stickers of things I have worked on. Focus one and use the arrow keys to move it.

  • Systems that talk banks, invoicing, CRMs
  • Bugs traced to the root SQL → logs → code
  • Busywork → internal tool Django, Laravel, React
  • Bank messages, translated SWIFT to ISO 20022
  • Invoices that retry e-invoicing in Colombia
  • Live in 5+ countries benefits platform
  • Data you can trust SQL and Python checks
  • Reports on autopilot SQL, PL/SQL, Excel

01 / What I do

Where I'm useful

  • 01

    System integrations

    Financial messaging (SWIFT MT and ISO 20022), electronic invoicing connectors and data workflows between systems that were never meant to talk.

  • 02

    Production support

    L2/L3 incidents traced through SQL, logs and code until the failure is clear, then a fix the team can maintain and a written root cause.

  • 03

    Internal tools

    Practical software teams use every day: estimation tools, inventory platforms, reports, queued exports and admin panels.
