Ibtisam Hassan

I've built production systems at Deltalabs for Curbside Health, supporting 200,000+ users across 35+ hospital systems, and I designed IqPod from the ground up at Invensphere. On Curbside Health, I work across Rails, React, GraphQL, clinical data models, FHIR mapping, and Epic integration. I helped cut analytics processing from several minutes to under a second through query refactoring, targeted indexes, and Sidekiq background jobs, while also building CKEditor tooling for structured clinical authoring. I've also shipped AkkioTech's AI chatbot platform, using Next.js, Rails, and LangchainRB to support 200+ daily conversations. My work includes dynamic business-tool mapping, phase-aware LLM context, message governance, and escalation workflows that reduce unnecessary handoffs to human agents. At Invensphere, I'm the sole system designer and primary engineer for an IoT occupancy platform spanning LoRaWAN, BLE, gRPC, Rails, React, MQTT, Docker, and CI/CD. I like hard problems, clear interfaces, boring infrastructure, and software that reaches real users.
