AMIT SINGH

Summary

Software engineer with 7+ years building and operating backend and platform systems across product safety, network operations and financial data. Primary depth in Python, AWS, event-driven workflows, CI/CD, relational data and production reliability; production experience with Claude, RAG, OpenSearch and human review, plus hands-on Go projects. Known for resolving cross-service failures, improving developer and operator workflows, and owning delivery through rollout and support.

Core Skills

Experience

• Root-caused a cross-service authorization regression to an identity-resolution change in a separately owned permission service; proved multiple IAM/SigV4 service-to-service permission paths shared the failure, established pre-production blast radius, and drove the source-service fix instead of a local workaround.
• Designed compliance-sensitive legal-hold recalculation across UI edits, asynchronous Jira events and scheduled reconciliation for separate Ring and Lab126 databases; retired cross-tenant debt by isolating Ring-specific criticality and ticket-update behavior.
• Own backend and full-stack delivery for a multi-tenant product-safety platform; shipped 10 production features, implemented least-privilege view-only access for notary and operational users, onboarded Blink and LEO, backfilled ~15K historical tickets, and supported ~50K Ring and ~25K Blink ticket records.
• Restored a production-critical missing-data workflow within ~10 hours, then drove Aurora/CloudWatch monitoring and safer database-change controls covering reviewed SQL, rollback planning, staged rehearsal and post-change verification.
• Built unit and integration coverage and led Lambda runtime upgrades; participated in a formal one-week-per-month on-call rotation, diagnosing dependency, CloudFormation deployment and pipeline-revision failures across team boundaries.
• Migrated Claude inference after model deprecation and built text/image analysis with confidence-based human review; automated workflows, reducing estimated manual effort by ~30% for Ring and ~80% for Lab126.
• Defined phased migration and automation plans, aligning stakeholders on scope, rollout risk and milestones; mentored two engineers through architecture/HLD, trade-offs, runbooks and local setup into ongoing ownership.

• Built and productionized Jenkins/Jira/Groovy CI/CD pipelines for multi-vendor device integration and configuration updates, supporting integration, beta, user-acceptance and production rollout.
• Designed and productionized a ServiceNow-grounded RAG assistant using OpenSearch, embeddings and an LLM; reduced repetitive operational queries by an estimated ~50% and recorded approximately ~80% response satisfaction.
• Led beta and user testing, refined answers using feedback, added human verification for uncertain responses, and built a weekly knowledge-refresh lifecycle with review snapshots and controlled retention.
• Drove production readiness with integration testing, runbooks, customer guides and operational handover; used FastAPI/Django, AWS Lambda, Kubernetes, Redis and SQL optimization.

• Built APIs and ETL pipelines integrating Vermeg Colline collateral/risk data and Bloomberg market feeds for bonds, equities and mutual funds within defined regional SLA windows.
• Led PostgreSQL migration and Snowflake-integrated data pipelines; improved API response time by ~30% through Python optimization, SQL tuning and CI/CD improvements.
• Monitored production data pipelines with Dynatrace and managed operational incidents through ServiceNow, improving reliability and recovery discipline.
