Software engineer focused on building automation, integrations, and backend services that reduce operational friction and improve customer support workflows. I work across Node.js/TypeScript and Python with AWS infrastructure and observability to deliver measurable impact (faster resolution, fewer incidents, and reduced manual effort). I’m comfortable owning end-to-end features: from designing pipelines and data extraction (web crawlers, OCR document processing) to building APIs and dashboards, validating integrations, and maintaining production reliability with auditable migrations and monitoring.…Software engineer focused on building automation, integrations, and backend services that reduce operational friction and improve customer support workflows.
