Backend Engineer \| Python, FastAPI, Kafka, AWS \| Building scalable microservices & real\-time data pipelines\. 2\.5\+ yrs delivering GxP\-compliant, high\-performance systems across logistics & retail domains\.

## About

Backend Engineer \| Python · FastAPI · Kafka · AWS \| Building Scalable, High\-Performance Systems I build backend systems that don't just work \- they perform under pressure\. With 2\.5\+ years of experience at Altimetrik, I've delivered production\-grade microservices, real\-time data pipelines, and RESTful APIs across two demanding domains \- logistics \(Freight Verify\) and retail \(Lululemon\) \- serving global clients with zero tolerance for downtime or data inconsistency\. Here's what I bring to the table: Performance\-first APIs \- Designed FastAPI microservices achieving \~0\.3s response latency under concurrent load, with Redis caching reducing DB round\-trips by \~40% Real\-time data at scale \- Built Kafka\-powered ingestion pipelines and 15\+ Airflow DAGs processing millions of records daily with >99% accuracy Cloud\-native thinking \- Deployed and scaled systems on AWS \(S3, Lambda, EC2, RDS\) with load balancing, CI/CD pipelines, and SonarQube\-enforced code quality Reliability by design \- ACID\-compliant transactions, GxP\-compliant audit trails, OAuth2/Auth0 security, and RDBMS\-backed data integrity across distributed systems I thrive in fast\-paced agile environments, enjoy working directly with clients, and care deeply about writing clean, maintainable code that scales\. Currently exploring senior backend engineering opportunities where I can architect systems end\-to\-end from API design to cloud infrastructure\. Open to connect and collaborate — let's build something great\.
