Continuous engineering updates in real-time. Discover week-on-week platform enhancements, latency optimizations, AI models, and upcoming target milestones across all enterprise products.
Resolved booking workflow failures, implemented regex-based phone number extraction directly from live call transcripts, and removed unnecessary number pronunciation confirmation steps for 100% automated booking execution.
Identified and resolved inaccuracies introduced when shifting the measurement window from 60s to 45s with a 5-second precheck. Recalibrated the processing pipeline to restore consistent vital estimation across variable camera feeds.
Replaced client-side localStorage JWT with Server Actions and SameSite HttpOnly cookies, eliminating Next.js middleware 307 redirect loops; provisioned HMAC-SHA256 signed webhooks for multi-tenant security.
Version-locked the production rPPG processor and generated a 74-sample ground-truth dataset spanning diverse age groups. Quantified bias, MAE, and offsets for HR (+9.0 offset, 22.2 MAE), RR (+3.7 offset), SpO2 (+4.4 offset), SBP (-10.9 offset), and DBP (-1.7 offset, 82.4% acceptance rate).
Completed core functional voice agent updates and integrated high-naturalness Indian English TTS voices for field deployment across hotel and clinic call centers.
Architected a parallel POS + CHROM signal extraction engine with a lightweight quality evaluator selecting the higher-confidence signal dynamically without modifying downstream vitals pipelines.
Deployed standard CPU action execution matrix connecting CRM lead state triggers to operational tool chains (medical slot checking, logistics package tracking, and automated status updates).
Visual drag-and-drop conversational pipeline builder integrated into the primary CRM contact dashboard.
Replaced simple Q&A pipeline with an end-to-end reasoning loop (User speaks → STT → LLM reasons → Tool call → Execution → Response) enabling real-time room bookings and appointment scheduling.
Implemented adaptive spatial-temporal filtering to eliminate ambient lighting noise and head movement distortions in real-world non-clinical environments.
Optimized total roundtrip latency budget by tuning model selection, trade-offs between model size and Time-to-First-Token (TTFT), achieving sub-second response times on standard CPU servers.
