CAROLINE MWANGI

@carolinemwangi4

Senior software engineer delivering large-scale AI/ML-enabled messaging and cloud platforms.

What I'm looking for

I’m looking to lead backend and distributed systems work where AI/ML and real-time performance matter—building reliable microservices, scaling data pipelines, and improving observability so releases are faster with fewer incidents.

I’m a Senior Software Engineer with 9+ years designing and delivering large-scale consumer and cloud platforms, specializing in AI/ML-enabled applications, distributed systems, and high-performance web services. I focus on building resilient microservices and performance-critical real-time communication systems at global scale.

At Snap, I help support a messaging platform serving 470M+ daily active users. I engineered high-throughput real-time messaging services and architected scalable conversation state and metadata services, optimizing read/write access patterns and decreasing message thread loading latency by 35%.

I’ve also built and integrated media ingestion, processing, and AI-powered media classification using Python, FastAPI, TensorFlow inference APIs, and AWS, plus strengthened reliability with observability dashboards and automation. Through automated CI/CD and testing pipelines, I reduced incident detection time by 40%, accelerated release cycles by 45%, and decreased production regressions by 30%.
