• Led development of the firm-wide Bifrost system — a distributed, unified GraphQL engine that powers real-time data streaming at scale for latency-sensitive web applications.
• Designed and extended a multi-protocol abstraction layer, enabling plug-and-play support for Kafka, Python generators, proprietary systems, and third-party APIs — reducing integration effort by over 60%.
• Built an extensible field indexing framework, reducing query latency from O(n) scans to <1ms and accelerating initial snapshot delivery by 10x for 100K+ record datasets.
• Authored standardized Root Cause Analysis (RCA) templates and led postmortems on critical production outages — setting the gold standard for incident analysis in Middleware.
• Led onboarding and infrastructure integration of high-visibility Discretionary Tech applications onto Bifrost and RAFT, including:
• FE PM Tool (Fundamental Equities Portfolio Management),
• STORM (System to Track Orders and Real-time Markets),
• SPARTA (CROP’s real-time trade and market intelligence system),
• and ETS (Energy Trading System) — enabling low-latency, reliable data streaming and enhanced operational visibility for trading desks.
• Observability & Distributed Tracing in Real-time Streaming Infrastructure
• Designed and integrated distributed tracing using OpenTelemetry to provide deep visibility across asynchronous request flows—from browser-based JavaScript clients to a multi-node Java backend.
• Enabled end-to-end traceability of critical operations (queries, mutations, subscriptions) over WebSocket and REST, ensuring observability across system and process boundaries.
• Built a robust span structure with meaningful metadata enrichment, enabling precise filtering and debugging in Jaeger.
• Focused on production-grade tracing practices, including span sampling, performance-aware instrumentation, and trace propagation across async and thread-switching flows.

• Played a pivotal role as a major developer in propelling the Bifrost initiative, a Unified GraphQL Engine. Executed significant tasks and key projects, enabling real-time streaming workflows and seamless integration with diverse data sources such as Kafka, and proprietary middleware.
• Provided guidance and mentorship to a campus hire and interns on projects involving technologies like Kafka, Java, and Python.
• Took complete ownership of product lifecycle, from development to release, including handling client queries and operational issues.
• Instrumental in achieving remarkable milestones, including a 5x improvement in real-time subscriptions query scalability and a substantial reduction in end-to-end and snapshot latency.
