Rishi Machanpalli

About

IAM/platform engineer with experience at DocuSign and Siemens who ships production-grade systems end-to-end: built a secure AWS serverless internal employee-profile API (OAuth2/Cognito/WAF) that cut data retrieval from weeks to near-instant and sustained ~2,800 RPS at ~75 ms. Also delivered production AI workflows, including a GPT-4o + Playwright crypto-scam detection agent and an NLP ticket-routing system improved to ~86.7% accuracy with strong monitoring and incident mitigation practices.

Key Strengths

• Owned secure internal API end-to-end (discovery through post-launch stabilization)
• Designed scalable, security-focused AWS serverless architecture (API Gateway/Lambda/DynamoDB/Cognito/WAF)
• Drove major operational improvement: reduced employee data retrieval from 2+ weeks to near-instant
• High-performance API validation via load testing: ~2,800 RPS at ~75 ms latency (k6/Grafana)
• Strong cross-functional stakeholder management (IT, security, platform teams; downstream consumers like Slack/ServiceNow)
• Production LLM workflow design with cost/latency control (single-call GPT-4o + deterministic regex extraction)
• Built robust dynamic web analysis pipeline (HTTP fallback to Playwright rendering; isolated browser contexts)
• Incident debugging and mitigation for ML systems (confidence thresholds, manual review queue, retraining, monitoring)
• Improved NLP ticket routing accuracy to ~86.7% and reduced misrouting impact for support teams
