– Lead a team of 5 engineers, providing technical direction, mentoring, and ownership of delivery.

– Designed and built a RAG-based chatbot system from scratch, including a continuous data ingestion pipeline and vectorization of both incoming and historical data, and source citation support for generated answers.

– Drove infrastructure migration to Terraform, establishing CI/CD for infrastructure as code, importing legacy resources, and managing ongoing infrastructure expansion.

– Successfully prepared a backend application for SOC 2 certification.

– Led the decomposition of a monolithic application into dozens of microservices, introducing NestJS, migrating services to GCP Cloud Run with a serverless architecture, and using GCP Pub/Sub as the messaging backbone.

– Introduced and implemented integration testing across services.

– Reduced deployment time from one hour to 15 minutes by implementing a robust CI/CD pipeline.

– Built infrastructure for feature toggles and canary release deployments using LaunchDarkly, and developed a dedicated microservice to manage feature flags at the tenant level.

– Designed and executed Taurus-based stress tests to validate system readiness for 5x peak load.

– Built a Redis caching layer between a microservice and a vendor API, cutting external API calls by 70%.

– Built an event-driven communication system using Kafka to replace a request-response model, resulting in more decoupled microservices, including idempotency mechanisms to ensure reliable message processing.

– Designed and ran complex multivariate A/B tests, using the LaunchDarkly platform for feature toggles and controlled rollouts.

– Designed and maintained a microservice using GraphQL as the API interface and PostgreSQL for data storage.
