Key Strengths

• Owned end-to-end Firebase-to-AWS backend migration (Lambda/API Gateway/DynamoDB) with shadow testing and zero downtime
• Cost optimization impact: reduced monthly infrastructure costs ~30–32% via serverless pay-per-use
• Scalability impact: supported 25% increase in active subcontractor teams post-migration
• Production monitoring/observability: CloudWatch dashboards, Sentry error tracking, AWS X-Ray tracing
• Strong DynamoDB single-table design and access-pattern-driven documentation/runbooks
• Built and productionized AI-native code assistant using RAG (LangChain + Pinecone) with code-aware chunking
• AI evaluation rigor: offline GPT-4 judge on 200+ tasks plus online metrics (acceptance rate, edit distance)
• Implemented AI safety guardrails: similarity-threshold refusal, security scans, jailbreak/injection pre-screening
• Legacy modernization leadership using API Gateway fronting, incremental routing, and dual-write strategy
• Stakeholder partnership (CEO/CTO/CPO): translated ambiguous enterprise-scaling goal into phased roadmap; onboarded 3 major firms in 6 months and drove 20% transaction volume increase
• Forward-deployed/customer-embedded execution across multiple design-partner firms with rapid prioritization
