Sole technical owner building the company’s end-to-end product stack from scratch, including the production web application, partner integrations, and cloud data infrastructure. Defined engineering strategy and architecture for all engineering workstreams, owning technology, infrastructure, and vendor decisions. Designed and delivered a production web platform (Django, React, Redis, Celery on AWS) for client operations and internal workflows. Architected an end-to-end data pipeline (EventBridge → API Gateway → Lambda → Glue → Athena → S3 → Clean Rooms) deployed via CloudFormation to transform partner data from ingestion to advertiser-ready analytics. Scoped and delivered a custom Shopify integration syncing partner catalogue data in near real-time, removing ~40 hours/month of manual data entry. Implemented attribution tracking using Amazon Ads tags and Google Tag Manager to provide campaign-level visibility for clients.

Contract engagement to take a product from concept to launch, with ownership of end-to-end architecture, delivery, and deployment decisions. Led product discovery to production launch: defined system architecture, selected technology stack, and managed the delivery roadmap independently. Designed microservices architecture (Django, FastAPI, Firebase) supporting a Flutter mobile app across iOS and Android with authentication, real-time sync, and push notifications. Ran iterative prototype cycles driven by user research to validate UX patterns before committing to final implementation.

Core engineering team building network management systems for a Google-backed small-cell infrastructure company. Owned design and delivery of mission-critical microservices processing telemetry data across network management, operations, and analytics. Redesigned core service architecture to improve API response times and throughput for high-frequency polling endpoints used by operations teams. Led security hardening of IoT management interfaces, applying research from an MSc to close vulnerabilities found during penetration testing. Designed an asynchronous inter-service communication layer to reduce data propagation latency between dependent microservices.
