About this gig

Legacy systems often hold years of valuable business databut theyre hard to access, integrate, or scale with modern software.


I help businesses unlock that data by turning outdated or disconnected sources into clean, secure REST APIs that your applications can actually use.


Whether your data is stored in an old database, spreadsheet, CSV files, XML exports, or legacy systems, I can transform it into a structured API with JSON responses that can be used across web apps, mobile apps, dashboards, or internal tools.


This means no more manual exports, no more messy workarounds, and no more systems that dont talk to each other.


What I can help you with:

  • Converting legacy databases into REST APIs
  • Building clean, structured endpoints from messy data sources
  • Adding search, filtering, and pagination where needed
  • Turning spreadsheets, CSVs, or XML files into usable data services
  • Creating APIs ready for integration with modern applications

How it works:

  1. You send your data source (database, file, or export)
  2. I analyse and structure the data
  3. I build a REST API tailored to your needs
  4. You receive working endpoints + documentation for integration
