Real architectural bottlenecks solved for CTOs, product directors, and enterprise scale-ups. Every metric verified through production APM telemetry.
Fault-Tolerant Fleet Telemetry & Event Streaming Mesh
Migrating a legacy centralized relational monolith into a multi-region Apache Kafka event-driven mesh processing 18,500 telemetry messages/second across 40+ transit nodes with zero packet loss.
The legacy monolithic relational database suffered catastrophic table lockups during peak dispatch surges, generating 42-minute dispatch queue delays for 3,400 active fleet units and unacceptable data drift.
Architected a distributed event ingestion pipeline using stateless Go microservices, Amazon MSK (Managed Kafka), and TimescaleDB with a Redis cluster for live spatial fleet rendering. Implemented automated dead-letter queues and Kubernetes HPA auto-scaling across AWS us-east-1 and eu-west-1.
18,500 TPS sustained
11.4ms (down from 1.8s)
-38% AWS bill reduction
HIPAA-Compliant Deterministic Multi-Agent Clinical Triage
Engineered a deterministic multi-agent state graph with LangGraph, isolated sandbox tool execution, and NeMo Guardrails to automate patient record synthesis and clinical triage without hallucination risks.
Emergency room intake nurses spent 26 minutes per patient manually reviewing disparate EHR records, resulting in severe clinical intake bottlenecks and heightened compliance vulnerabilities under HIPAA Title II.
Designed a multi-agent state graph where a Supervisor agent orchestrates task distribution to isolated workers: an EHR Parser (FHIR-compliant), a Hybrid Semantic Retriever (Qdrant vector store), and a Verification Guardrail agent that validates clinical constraints before doctor review.
4.8x faster intake triage
Zero out-of-policy output
100% HIPAA Tokenized transit
High-Concurrency Multi-Currency Settlement Engine
Engineered a sub-15ms clearing and ledger settlement gateway utilizing Java 21 virtual threads, Spring Boot 3, and optimistic locking algorithms on AWS Aurora PostgreSQL with automated SOC 2 audit logging.
Cross-border transaction clearing spikes caused database deadlocks, leading to unconfirmed ledger states, transaction retries, and manual reconciliation overhead totaling $35k/month.
Engineered an idempotent transaction processing pipeline with distributed Redis lock tokens, partitioned ledger accounts, and asynchronous dead-letter queues. Automated full audit telemetry into immutable S3 write-once-read-many (WORM) storage.
