Serverless Status Normalization Endpoints
Budget: $15 – $25 USD
Roles: Full Stack Engineer (Platform Integrations) / DevOps Engineer (Application Reliability)
You will design, build, and operate backend services and job workflows that keep external provider data in sync with internal records. The role focuses on secure serverless APIs, third-party integrations, database updates with correctness guarantees, and production-grade observability and operational controls.
Responsibilities
Build serverless API routes and internal job endpoints using Next.js, including robust request handling, validation, and environment-aware security controls.
Implement secure job triggering and verification (e.g., signature verification for queued/async job delivery) to protect internal endpoints.
Integrate external provider APIs and data sources, including:
constructing authenticated requests, handling non-200 responses, parsing variable payload shapes, extracting status/error details consistently.
Develop reliable reconciliation/backfill logic over configurable time windows and limits, ensuring:
correct filtering of eligible records, minimum-age protections to avoid racing in-flight events, deterministic status updates using priority rules to prevent regressions.
Design database update flows in Supabase/Postgres that are safe and idempotent, updating related entities when appropriate.
Implement batching and controlled concurrency to balance throughput with external API limits and internal resource usage.
Create provider error normalization and internal categorization, recording invalid destinations and storing structured metadata for audits and future prevention.
Support production operations: debugging failures, improving retry behavior, reducing skipped/error rates, and adding metrics/logging for job health.
What you’ll work with
TypeScript, Next.js (serverless route handlers)
Supabase (Postgres + API clients)
Async job delivery / queueing concepts (signature verification, replay safety)
Third-party API integrations (authenticated fetch, response normalization)
Operational patterns: batching, caching, rate-limit awareness, and resilience
Qualifications (recommended)
Strong TypeScript/Node.js backend experience, including async/concurrency patterns.
Experience designing and operating production integrations with external APIs.
Solid SQL/Postgres fundamentals; comfortable with data integrity and safe update patterns.
Familiarity with serverless deployments, environment configuration, and secure endpoint design.
Ability to instrument systems (logs/metrics) and troubleshoot production issues end-to-end.
