⚡ Amazon projects get complicated quickly: SP-API auth, quotas, incomplete data, missing webhooks, asynchronous processing, production incidents.
🔧 I help product and tech teams set up robust SP-API integrations: data collection, normalization, storage, asynchronous jobs, and exposing data via internal APIs. My approach: start with the business need, reduce Amazon coupling, and build a maintainable pipeline (logs, retries, idempotency, monitoring). I can work on Python backends, third-party integrations, workflow automation, performance, and quality improvements.
🚀 Currently, I'm building sales-pulse.app, an Amazon SaaS (SP-API + AWS + asynchronous workers + notifications). I have 7 years of backend experience, and I was an Amazon seller, so I understand operational constraints. I work 100% remotely, for short-term support or long-term missions.
