Working on the real-time and workflow foundations of an early-stage gastrotech startup, shaping AI-ready service boundaries and dependable product experiences as the idea moves quickly.

Built a hexagonal .NET integration for Vertex tax services on AWS, with secure APIs, idempotent submissions, and reliable message recovery. Automated infrastructure and delivery while protecting contract mapping and transaction integrity.

Built event-driven chargeback workflows with Kafka and Temporal, correlating payment, order, and logistics events. Hardened processing against duplicates and failures, deployed Java services on EKS, and improved read-heavy workflows with Redis caching.

Modernized Java services for energy operations with reliable routing, real-time WebSocket updates, and fault-tolerant messaging. Standardized Kubernetes delivery through Terraform and GitOps, with typed gRPC contracts and tracing across service boundaries.

Clarified backend business rules with behavior-driven acceptance tests and secured multi-region workflows with centralized authentication. Automated container builds and Azure deployments, improving release repeatability and operational visibility.

Reshaped a tightly coupled Node.js application into a modular monolith with clear boundaries and dependency injection. Built resilient inventory and employee-update processing, backed by retries, dead-letter recovery, automated tests, and repeatable serverless infrastructure.

Built campaign-metrics APIs and scheduled reporting jobs that standardized data across marketing channels. Used AWS serverless services and automated deployments to improve reporting consistency and reduce manual work.
