Souvik Nath
Full Stack Engineer & AI Developer
I'm a Python Full Stack Engineer with 3+ years of experience building scalable fintech applications, production APIs, and AI-powered SaaS products. My work includes Django, FastAPI, Next.js, TypeScript, PostgreSQL, Celery, Redis, Kafka, OpenAI, RAG, semantic search, and vector databases.
I enjoy designing clean architectures, developing secure backend systems, and turning complex workflows into reliable products that deliver real business value.

My Journey
From Full Stack
to AI-Powered Systems
Building on a strong software engineering foundation while expanding into practical AI, intelligent workflows, and scalable SaaS products.
My journey began with full-stack development, building production web applications using React, Next.js, TypeScript, Django, Django REST Framework, FastAPI, and PostgreSQL. Working on enterprise fintech systems helped me strengthen my skills in API design, authentication, asynchronous processing, database optimization, and scalable backend architecture.
Over time, I expanded into AI-powered product development, working with OpenAI APIs, embeddings, semantic search, Retrieval-Augmented Generation, and vector databases. That journey led me to build Aura Finance, an AI-powered personal finance platform that combines intelligent document processing, transaction categorization, background jobs, and financial insights.
Today, I focus on building reliable full-stack and AI systems that combine clean architecture, production-grade APIs, thoughtful user experience, and practical AI workflows.

Engineering Principles
Secure by Design,
Built to Scale.
I design applications with security, reliability, performance, and maintainability in mind from the beginning. My approach combines secure authentication, clear API contracts, optimized data access, asynchronous processing, and modular architecture to build systems that can grow safely.
Security
JWT authentication, role-based access control, protected APIs, validation, and user-specific data isolation.
Performance
Optimized database queries, indexing, caching, pagination, and asynchronous processing for responsive applications.
Reliability
Background jobs, retry workflows, error handling, observability, and clear service boundaries for dependable systems.
Scalability
Clean architecture, modular services, event-driven workflows, cloud storage, and containerized deployment.
