About

Engineer building enterprise AI systems and distributed platforms that replace expensive commercial software. Currently a Senior Software Engineer at Philips Healthcare, where I design and operate production systems at the intersection of Generative AI, distributed architecture, and enterprise workflow automation. Most recently, I architected and delivered a global RFP and tender automation platform used by Philips sales teams. The system combines retrieval-augmented generation (RAG), custom retrieval strategies, and document intelligence pipelines to automate complex procurement workflows. Impact: • 80% reduction in proposal turnaround time • 1000+ RFP workflows processed monthly • Replaced a commercial platform costing ~$6M annually Beyond AI platforms, I’ve also built core backend infrastructure used across internal systems: • Designed Kafka-driven microservice architectures supporting document ingestion and workflow orchestration • Built a centralized authentication and authorization service with JWT security and fine-grained RBAC • Developed an internal microservice framework that reduced service setup time from days to under an hour • Led migration of enterprise workflows from Appian to Camunda, eliminating vendor lock-in and saving ~$4M in annual licensing costs My focus is making AI systems production-ready through strong architecture, deterministic evaluation, observability, and scalable distributed systems. Technical focus areas: • AI systems: RAG pipelines, LLM evaluation, LangGraph workflows • Backend architecture: distributed microservices, event-driven systems, Kafka • Infrastructure: Kubernetes, Docker, AWS, CI/CD and observability You can explore detailed system architecture breakdowns and projects here: 🌐 https://www.sinsak.in/ I’m currently open to new opportunities involving AI infrastructure, backend platform engineering, and large-scale distributed systems. 📧 hire.sakshamsingh@outlook.com
