• Assistant's core runtime platform responsible for multimodal conversation management, and for orchestrating various ML / NLP sub-services at query time.

• Infrastructure to facilitate advanced conversational experiences via coordinating tightly coupled microservices.

• Real-time delivery of speculative responses via bidirectional gRPC streaming.

• Centralized serving components for user-state and context (persistence + retrieval), action execution, fulfiller selection etc.

• Libraries and central infrastructure for dialog and user/session state-management, empowering dozens of teams developing Assistant features.

• Engine to handle complex multi-intent dialogs, broadening semantic understanding and overall query recall.

• Key components of the NLU platform, to enable the development of dialog-flows across multiple feature domains.

• Developer tooling to improve debuggability and observability across all Assistant features.

• Latency and capacity optimizations in the intent-to-fulfiller routing layer.

(Mentor Graphics was acquired by Siemens)

R&D for the core backend of SLEC, leading formal equivalence-checking software for digital systems.

• Specifically, the tool performs sequential equivalence checking of C/C++ spec against RTL (hardware model) which the output of HLS (high-level synthesis).

• Implemented algorithms leveraging automated inductive reasoning to optimize, simulate and analyze operator-graph representations of users' designs.

• The work involved dealing with the challenges of implementing scalable verification software, as well as brainstorming theoretical improvements to extract practical value from an equivalence-checker.

(Calypto was acquired by Mentor Graphics)

• Developed algorithms to optimize a compute-intensive software tool for formal property verification (5+ hr tasks).

• Developed a sub-product to perform bounded-verification for intractable models.

• Implemented heuristics and flows to orchestrate formal proofs via various backend constraint-solvers (bit-level, SAT/SMT, logic simulation).
