PROFILE

Hritik Raj

Worked across envoyproxy/ai-gateway, NVIDIA/NeMo-Agent-Toolkit, and llm-d/llm-d to deliver features and fixes focused on backend reliability, observability, and configuration flexibility. Built dynamic CLI overrides in Python to streamline evaluation workflows, and enhanced PromQL-based monitoring and load analysis using scripting. In Go and Kubernetes environments, addressed cross-namespace routing bugs, implemented structured error handling with granular metrics, and introduced per-backend labeling for MCP metrics to improve operational insight. Developed robust JSON-RPC response decoding and improved route reconciliation logic, ensuring accurate status reporting and error propagation. Demonstrated disciplined commit practices, clear traceability, and strong instrumentation skills throughout all contributions.

Jun 1, 2026

June 2026 monthly summary for envoyproxy/ai-gateway: Delivered a critical fix to route reconciliation when a referenced gateway is missing, improving accuracy of route statuses and overall reliability of the gateway. The change ensures missing gateways are treated as errors rather than silent successes, propagating the error through the reconciliation loop to prevent stale state. This reduces misreported Accepted routes, improves observability, and enhances maintainability of gateway routes. Commit reference tracked for traceability.

April 2026 monthly summary (envoyproxy/ai-gateway). Key feature and reliability work delivered focused on the MCP Proxy path. Implemented a robust JSON-RPC response decoding cascade to handle heterogeneous MCP backend formats, significantly improving proxy reliability when facing inconsistent responses. What was delivered: - Robust MCP JSON-RPC response decoder supporting three formats: raw JSON, gzip-compressed JSON without reliable headers, and SSE-framed data. This was implemented as a cascading fallback strategy, reducing decode failures across backends. - Commit: d50462a9b47c71c4efd9b80c046f4f83e24e4dfd (mcp: jsonrpc response fix (#1997)). The change closes existing related issue #1996 and aligns with the MCP proxy reliability objectives. Impact and accomplishments: - Higher MCP proxy reliability and resilience against backend formatting inconsistencies, leading to fewer failed requests and improved service SLA for the MCP path. - Clearer handling of edge cases in backend responses reduces manual triage and increases stability in production deployments. Technologies and skills demonstrated: - JSON parsing and validation, gzip detection/decompression, and SSE-framed data handling. - Robust error handling and cascading fallback logic under varying backend formats. - Code hygiene, traceability to related issues/PRs, and contribution sign-off practices.

March 2026: Implemented MCP Backend Metrics Labeling for envoyproxy/ai-gateway, introducing a new mcp_backend label to all MCP metrics to enable backend-level observability. This enables per-backend monitoring and performance analysis across MCP backends, supporting faster incident response and more accurate capacity planning. The feature was delivered via PR #1886 with commit 98361980f78276dafa2440cec03ea916c007433a, adding the mcp_backend label and updating metrics (e.g., mcp_initialization_duration_token_sum, mcp_request_duration_sum, mcp_method_count_total) with per-backend breakdowns.

December 2025 was focused on strengthening MCP reliability and observability in envoyproxy/ai-gateway. Key delivery: MCP Error Handling Framework and Error Metrics, introducing a structured error type, errorType classification, and dedicated metrics to distinguish application vs protocol errors for tool calls. Enhanced error recording in servePost to mark application errors as 'failed' and consistently update MCP metrics. Implemented end-to-end instrumentation for MCP tool calls (e.g., mcp_method_count_total, mcp_request_duration_count) and expanded tests to validate success and error pathways. This improves diagnosability, SLA reporting, and operational visibility, enabling faster incident response and data-driven improvements. Related PRs: #1663; Fixes #1661.
