A bit about me

I'm a Senior Software Engineer who specialises in agentic AI systems and cloud-native infrastructure. Started my career at IHX processing millions of medical documents daily, where I learned what it means to build systems that can't go down. Moved to Mphasis Applied AI to see how AI products get built and sold to enterprise — and ended up building ATOM, an agent platform I initially designed as an OSS project that's now running in production for BFSI clients.

I care most about the control plane around agents — auth, policy enforcement, observability, isolation. The agent logic is often the easy part. The infra that makes it safe and auditable is where the real engineering is.

key highlights
Built ATOM — an on-prem agentic platform where engineers write agents via SDK and ship with a single command. Every LLM call is policy-checked and immutably logged.
Reduced DB query time from 1–2s to 10–15ms across 10 tables at IHX.
Status notification system processing 10M+ messages per day using SNS.
Document intelligence platform that improved first-submission claim rate from 23% → 77% in 2 weeks. Now classifies 4M+ images/month.

ATOM — Agentic Development & Deployment Platform
AgentScope · TypeScript · Golang · FastAPI · Docker · Kubernetes · Kafka/Redpanda · OPA · PostgreSQL · Redis · Grafana Alloy · Loki · Tempo
On-premises agentic platform for financial services — write agents via SDK, deploy with a single command. Infrastructure, compliance, guardrails, and LLM routing are fully abstracted. Every LLM call flows through GATE (JWT auth, OPA policy, rate limits, immutable audit log). Agents run as isolated containers via atom-runtime; Studio UI handles lifecycle and HITL. OSS core at github.com/shreyasY2k/atom.
NexusAI — Enterprise LLM Gateway
LiteLLM · FastAPI · Python · PostgreSQL · Redis · Docker
Multi-tenant LLM gateway serving enterprise BFSI clients. Per-tenant API key management, budget governance, PII-aware routing, and audit logging. Full compliance coverage for PCI-DSS, FIPS, GDPR, and DORA.
IHX — A PERFIOS COMPANY
Senior Software Engineer
Jul 2024 → Feb 2025
Orchestration Engine
Netflix Conductor · Zookeeper · Redis Sentinel · TypeScript
Comprehensive workflow orchestration for document processing pipelines — extraction, OCR, classification, quality control. Parallel processing patterns reduced processing time by 40%.
Persistence Engine
TypeScript · TypeORM · PostgreSQL · Redis
Single-layer persistence solution reducing average query time from 1–2s to 10–15ms across 10 tables.
Status Notification Service
TypeScript · AWS SQS · AWS SNS · MongoDB
High-throughput system processing 10M+ messages daily, providing real-time status visibility across AI/ML entities to client dashboards.

Document Intelligence Platform
TypeScript · FastAPI · AWS EKS · MongoDB · S3
Document processing platform for India's largest health benefits administrator. Took first-submission claim rate from 23% → 77% in 2 weeks. The platform now classifies over 4 million medical images every month.
Infrastructure Transformation
Kubernetes · Helm · NGINX · Grafana · Loki · Promtail · Prometheus · Service Accounts
Led Kubernetes and AWS infrastructure design for AI model security and scaling. Introduced full observability stack, enabling rapid feature deployment.
Authentication Solution
Keycloak · Java · OAuth 2.0 · JWT · NGINX
MFA and SSO with Keycloak custom plugins across multiple services — reduced login time by 50%.
