Work History
Software Development Engineer 2 - GenAI Platform
VIAVI Solutions, Inc.
07.2025 - Current
- Joined GenAI initiative as 2nd engineer; built ReAct LangGraph-based custom conversational agent for Tier-1 telecom troubleshooting, KPI exploration, and RCA.
- Built custom tool layer for enterprise data access (Postgres, Vertica) to support NL-driven analytics across telecom datasets.
- Engineered metadata-aware NL to SQL generation for large schemas/high-cardinality values, improving correctness and reducing failed query loops.
- Shipped deterministic report generation using template enforcement, composing DB outputs + tool results into customer-ready formats.
- Implemented pre/post guardrails against jailbreak/prompt injection and policy violations; reduced jailbreak success 24% to 0.4% and improved targeted-attack blocking 95.3% to 99.3% via Promptfoo red teaming.
- Re-architected the platform into Telion, a product/use-case-agnostic foundation with observability/audit logging + prompt management (Langfuse), multi-LLM routing/failover (LiteLLM), scalable MCP tool servers (ToolHive), and retrieval integration (RAGFlow)
- Tech-led delivery across a 5-person multi-time-zone team (3 UK DevOps, 2 US engineers); drove execution, updates, and adoption.
- Onboarded and mentored 2 rotational engineers across agent framework, guardrails, and production workflows.
- Co-led Claude Code rollout company-wide; ran info sessions and briefed execs on AI engineering adoption and productivity signals.
