01About

Systems that fail quietly, not loudly.

I'm a software engineer who specializes in building scalable backend systems and integrating AI into real-world products. My strengths lie in designing FastAPI services, event-driven architectures, LLM-powered pipelines, and cloud-native solutions on AWS and Azure — writing code that holds up under production load and is easy to evolve.

I'm comfortable working across the backend stack — from data modeling and API design to async pipelines, caching strategies, and RAG systems. I enjoy the work that sits at the intersection of backend engineering and Generative AI: making intelligent features fast, reliable, and cost-effective to run.

Long-term, I'm working towards becoming a Solution Architect — someone who can look at a business problem and design the right system for it, not just the technically interesting one. That means thinking beyond individual services to how systems interact, scale, and fail gracefully.

    Software Engineer

    ·Simform Solutions/ Remote
    • Architected a multi-tenant FastAPI backend using a strict repository + service pattern (SOLID-aligned), reducing code change ripple effects by 40%.
    • Optimized API performance via query path refactoring, pagination, and selective serializer variants, cutting P95 response time from 480 ms to 210 ms and reducing DB query count per request by 55%.
    • Built an event-driven notification framework over Redis Streams, enabling real-time tenant alerts, audit trails, and reactive data pipelines (latency ↓65%, scalability ↑3x).
    • Designed and implemented a robust RBAC system with centralized authorization policies, strengthening security and simplifying permission management.
    • Integrated Azure Functions and Graph API utilities for asynchronous tenant operations, improving throughput capacity by 45% under peak load.
    • Developed an LLM-powered document intelligence pipeline to extract structured knowledge from unstructured documents and ingest it into reporting systems, enabling real-time analytics.
    • Built a scalable Document Manager service handling thousands of documents with secure storage, retrieval, versioning, and lifecycle management in Azure Blob Storage — reducing operational overhead by 54%.
