Krishna Nichal
Enterprise Backend & AI Architect
Designing, scaling, and optimizing distributed microservices, Backend-for-Frontend (BFF) layers, and production-ready Agentic AI workflows with high-concurrency Node.js, TypeScript, and Python architectures.
Engineering Mindset & Approach
Architecture & Quality
Building high-throughput backends designed for performance, maintainability, and clean separation of concerns. From bypassing rigid third-party vendor limits to reducing downstream API latency.
Trust & Relationships
Believing in long-term technical leadership grounded in clear communication, transparency, and a commitment to delivery—whether collaborating as a team lead or a strategic consultant.
Continuous Growth
Constantly bridging enterprise backend principles with modern breakthroughs like Agentic AI, FastAPI task orchestration, and Graph-RAG retrieval systems.
Core Capabilities
Enterprise Backend & BFF Systems
Architecting resilient Backend-for-Frontend layers and microservices using Node.js, Express, NestJS, and GraphQL. Experienced in distributed caching strategies (Redis) that slash latency by over 40%.
- 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
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.
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%.
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.
