RESTful API Jobs

I am ready to move an idea from concept to a fully-deployed Python solution and need a developer who writes clean, well-structured, thoroughly documented code.

Because the exact business logic will be shared after kickoff, versatility is important. Familiarity with automation workflows, data-analysis pipelines, RESTful or GraphQL APIs, and modern AI/ML libraries (Pandas, NumPy, scikit-learn, TensorFlow, or similar) will allow you to hit the ground running, yet please stay pragmatic—choose only what the project truly needs. From you I would like: • A concise project timeline that breaks work into clear ...

I have a custom integration that keeps Total Synergy and Trello in sync through their public REST APIs. Lately, I’ve spotted dates drifting out of alignment, so the immediate objective is to pinpoint where the sync is breaking down – I’m not chasing speed improvements yet, just accuracy.

This is a one-time fix. However, if your work is excellent and meets expectations, there is an opportunity for another job within the same system involving changes and further debugging. Deliverables: • Ensure all noted di...
