  • GraphQL & REST API Design
  • Distributed Caching & Redis Optimization
  • Microservices & NestJS Ecosystems

Agentic AI & Data Orchestration

Designing context-aware multi-agent task orchestration backends using Python and FastAPI. Utilizing Memgraph for Graph-RAG pipelines, Pydantic v2 for type-safe validation, and Chain-of-Thought prompting.

  • FastAPI & Async Python Engineering
  • Graph-RAG & Memgraph Integration
  • Chain-of-Thought Task Routing

Integrations & Cloud Infrastructure

Solving complex integration challenges including SAML/SSO security brokers, digital payment gateways, and real-time logistics engines using AWS Lambda, Docker, and Nx-Monorepos.

  • AWS Lambda & Serverless Brokers
  • Single Sign-On (SSO / SAML) Security
  • CI/CD & Nx-Monorepo Management

Featured Architectural Highlights

AI & Orchestration

Asynchronous Agentic AI System

Pioneered an enterprise R&D task orchestration backend using Python and FastAPI. Built a Graph-RAG retrieval pipeline leveraging Memgraph and Chain-of-Thought prompting for context-aware, autonomous semantic routing.

BFF & Enterprise E-Commerce

Enterprise Storefront BFF Layer

Digitized offline spreadsheet order processes into a unified GraphQL storefront interface. Integrated payment gateways and logistics engines, using Redis caching to reduce downstream API latency by 40%.

High Concurrency & Analytics

AtHoc Command Center Platform

Architected a highly configurable dashboard engine for a critical platform, allowing dynamic real-time reporting. Led the transition to modern client architectures with live geofencing modules.
