I will build an automated data pipeline and api integration system
About this Gig
Your systems don't talk to each other. A CRM that doesn't know what billing knows. An API that returns exactly what you need, if only something were listening. I build the layer in between and I build it to keep running after handover.
I design automated data pipelines and API integrations that move data on a schedule, handle failures without silently dropping records, and log enough that you can tell what happened three weeks later. A system, not a script.
Typical work:
- API to database pull, validate, write to PostgreSQL, SQL Server, MongoDB
- System to system CRM, ERP, e-commerce, internal tools in sync
- Scheduled ETL and webhook handling, with retries
- File automation CSV, Excel, Sheets
- Geospatial pipelines ArcGIS, PostGIS
You get: working pipeline in your repo, incremental sync, retry logic, structured logging, setup docs, and source code on every package.
Stack: Python, .NET Core, Node.js · PostgreSQL/PostGIS, SQL Server, MongoDB · RabbitMQ, Kafka · REST, webhooks · Docker, AWS · ArcGIS REST API

Message me with what you're connecting and how often it runs I'll tell you which package fits.

FAQ
Will this keep running after delivery?
Yes. Everything I build is designed to run on a schedule or trigger without supervision. You get the source code, deployment instructions, and logging so you can see it working. Post-delivery support is available as an extra if you'd like me monitoring it for the first month.
What if the API I need doesn't have documentation?
Common, and not a blocker. I've reverse-engineered plenty of undocumented endpoints from network traffic or partial specs. Send me what you have and I'll tell you what's feasible before you order.
Can you work with my existing codebase?
Yes. I'll match your conventions, structure, and stack rather than dropping in something foreign. Send a repo link or a representative file.
Do you handle authentication — OAuth, API keys, tokens?
Yes, including OAuth 2.0 flows, token refresh, and secure credential storage. I never hardcode secrets.
Can you migrate our historical data too?
Yes — that's the backfill extra. Tell me the volume and date range and I'll quote it.
Do you sign NDAs?
Happily. Send it over before we start.
