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 [login to view URL], 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, [login to view URL] (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.

Hello, I’ve built and operated production-grade [login to view URL] serverless backends that keep external provider data in sync with internal systems, using TypeScript, Postgres, and secure async job patterns. In a recent platform integration project, I implemented signed job endpoints, provider API normalization, idempotent Supabase updates, and backfill logic with age windows and priority-based status resolution to avoid regressions. For your role, I would focus on clean [login to view URL] route handlers with strict validation, signature verification for queued jobs, and environment-aware security. I’ll design safe, idempotent Postgres update flows, controlled batching with rate-limit awareness, and deterministic reconciliation logic, plus structured error normalization and audit metadata. Operationally, I’m comfortable adding logs, metrics, retries, and debugging live issues end-to-end to improve reliability and reduce skipped or failed jobs. I can start your project immediately and will deliver robust, scalable, and well-instrumented integrations with a strong focus on correctness and long-term maintainability. Best regards, Elenilson

Hello, As a Full-Stack Developer, I check all the boxes outlined in this project description. My expertise with TypeScript and Node.js, async/concurrency patterns, serverless deployments, and secure endpoint design align seamlessly with the required skills. Throughout my career, I have gained considerable experience in integrating third-party APIs and ensuring consistent extraction of data while handling non-200 responses. In addition to this, I have dealt extensively with database updates using Postgres and Supabase, which should prove valuable for your project's needs. Moreover, I'm well-versed in operational patterns such as batching, caching and rate-limit awareness that can help ensure smooth throughput balancing while staying within API limits. With an added bonus of my ability to instrument systems (logs/metrics) and troubleshoot end-to-end production issues effectively, you can be assured of reliable performance at every step of the way. When it comes to this role of building secure serverless APIs and ensuring production-grade observability, my extensive backend experience using Python for REST APIs development and automation tools will certainly come in handy. Trust me to create a robust system that ensures reliable synchronization of internal records with external provider data while guaranteeing operational controls and security. Let's discuss in-depth how we can achieve your project goals together. Thanks!

You’re not looking for someone to “write endpoints.” You’re looking for someone who understands why integrations fail in production — and how to design them so they don’t. For the past 20 years, I’ve built and operated backend systems where correctness, observability, and resilience were non-negotiable. The patterns you described — idempotent updates, signature verification, deterministic reconciliation logic, safe concurrency, and provider-error normalization — are exactly the kinds of problems I specialize in solving because they’re what separate a working demo from a production-grade platform. Here’s how I approach work like yours: - I design APIs assuming providers will fail, retry, misorder events, and send malformed payloads. - I build job workflows that are replay-safe, traceable, and measurable. - I treat database writes as critical infrastructure, not simple CRUD. - I instrument everything so failures can be diagnosed in minutes, not days. - I optimize for long-term system stability, not short-term feature delivery. In short: I don’t just ship integrations. I build integration systems you can trust. If you want someone who can take ownership of reliability, not just implementation, I’d be glad to discuss your architecture and where you’re currently seeing risk or friction.
