Deepshika Pillai

I’m a Senior Software Developer and AI Engineer with 2+ years of hands-on experience shipping production-grade Python backends, RESTful APIs, and AI/ML systems. I’ve delivered 4 production-level products across pharma MES, IoT SaaS, SCADA, and incident management—2 of them architected from the ground up.

My core expertise spans FastAPI and Java Spring Boot, plus LLM/RAG pipelines for GenAI workflows. I bring end-to-end engineering with NLP, deep learning, and MLOps—so models and services don’t just work in demos, they perform reliably in production. I’m also comfortable building scalable microservices with Docker and AWS.

I’ve built systems with strong regulatory discipline, including 21 CFR Part 11 and GxP validation (FAT, UAT, IQ, OQ, PQ). In industrial settings, I’ve integrated IIoT data flows using OPC UA and MQTT, and worked with Kepware/Prosys to connect OT environments to application backends. For example, I architected a 21 CFR Part 11 compliant Pharma MES from scratch and led the full validation lifecycle, engineering 200+ REST APIs while achieving 99.9% uptime in a high-throughput environment.

I enjoy tackling “hard” product problems with measurable impact. In a GenAI-powered FHIR search engine, I built a LangChain-based RAG pipeline and reduced query turnaround by 50% by enabling non-technical users to extract clinical insights without SQL. I’ve also shipped an IoT SaaS backend with 500+ connected devices and improved voice-to-text transcription accuracy (92%), alongside backend and API improvements across Java Spring Boot + SQL systems—always focused on security, performance, and dependable releases.
