Custom development
APIs & data pipelines
Connect your tools, move data reliably and make it ready for the people and systems that use it.
I build Python APIs and data pipelines that connect separate tools into one working system. This can mean a custom backend, a webhook bridge, a scheduled import or a pipeline that collects and prepares data for dashboards and analysis.
Beyond moving data, I build the controls that make integrations practical to operate: authentication, validation, deduplication, retries, storage, monitoring and replay tools. Each pipeline is shaped around its sources, update frequency and destination requirements.
What I can build
Choose the modules your project needs. The features, integrations and delivery scope are agreed around your requirements.
Custom Python APIs
- REST APIs, request validation and documented schemas
- Authentication, permissions and rate controls
- Database-backed endpoints and background tasks
Tool & platform integrations
- API adapters and webhook producers / consumers
- Authentication and token-renewal workflows
- Field mapping and cross-system synchronization
Data collection & processing
- Batch imports and scheduled ingestion
- Cleaning, deduplication and enrichment
- Data-quality checks and quarantine workflows
Queues & reliable jobs
- Background workers and scheduled tasks
- Idempotency keys, checkpoints and bounded retries
- Failed-job queues, replays and historical backfills
Dashboards & reporting
- Pipeline status and data-freshness views
- Search, filters and CSV / report exports
- Job history, failure inspection and replay controls
Deployment & observability
- Container or server deployment configuration
- Health checks, structured logs and alerts
- API documentation and maintenance runbooks
System architecture
From a source event to usable data
An ingestion and delivery system with real connections between sources, queues, processing, storage and destinations. Recovery paths route invalid records, failed jobs and backfills through the appropriate checks.
Traceable jobs
Carry a job ID from intake to delivery so operators can find the source of a failure.
Recoverable processing
Use durable state, bounded retries and replay controls to handle interruptions without blind resubmission.
Data access controls
Scope API credentials, protect stored secrets and redact sensitive values in operational logs.
Explore how the modules connect
Select any module to see what it receives, what it sends and the rules it applies. Connected paths light up in the direction the data travels.
Keyboard: Tab to a module, Enter to select, Escape to clear.
What you receive
A working system and the documentation to operate it. Handover is tailored to the modules included in your project.
- Working API or pipeline with agreed source integrations
- API schemas, example requests and data mappings
- Monitoring and recovery / replay instructions
- Deployment configuration and operating documentation
