Hi, I'm Umesh
Badsara.
I build scalable backend systems, REST APIs, and database-driven web applications using Django and MySQL.
Who I Am
I'm a Computer Science student and aspiring backend developer passionate about building systems that are structured, secure, and scalable. I specialize in Django, REST APIs, authentication systems, and relational databases.
I enjoy designing clean database schemas, writing maintainable backend code, and building CRUD-based systems with proper authorization. I'm actively seeking opportunities as a Backend Developer / Django Developer.
Fresher Backend Developer with hands-on experience in building backend systems using Django and MySQL. Skilled in developing RESTful APIs, implementing authentication and authorization, designing relational database schemas, and building CRUD-based web applications. Strong understanding of backend architecture, database relationships, and API testing using Postman. Passionate about creating scalable, secure, and maintainable backend solutions, and eager to start a career as a Django Backend Developer.

Experience
My professional journey and key backend contributions.
ArtSpot Technology
Backend Developer
Migrated legacy DjangoObjectType definitions to GrapheneObjectType, modernizing the GraphQL schema layer and improving type consistency across the API.
Designed and implemented a Ratings & Reviews system for both products and shops, including backend models, GraphQL mutations/queries, and business logic for aggregation.
Zetheta Algorithms Private Limited
Backend Developer
Built a production-grade, event-driven notification engine for a fintech platform capable of handling 2M+ notifications per day with sub-second delivery latency for critical alerts.
Designed a multi-stage pipeline using Apache Kafka for high-volume ingestion and RabbitMQ priority queues for reliable dispatch across SMS, Email, Push, WhatsApp, and In-App channels.
Implemented a regulatory compliance engine enforcing TRAI DND scrubbing, Redis-based sliding-window frequency capping, and timezone-aware quiet-hours scheduling.
Built custom stateful circuit breakers with automatic provider failover (MSG91 → Twilio, WhatsApp Cloud API) and end-to-end correlation tracking via Prometheus metrics and Pino logging.
Backend Developer
Developed a production-grade payment orchestration system capable of routing transactions across multiple payment gateways (Razorpay, Stripe, PayU, and UPI).
Implemented intelligent gateway selection based on performance metrics, success rates, latency, cost, and health status.
Designed a robust transaction state machine with complete audit trails, idempotency handling, webhook processing, and automated reconciliation mechanisms.
Built fault-tolerant failover strategies and circuit breaker patterns to ensure high availability and transaction reliability.
Projects
Backend systems I've built using Django, REST APIs, and MySQL.
Store Backend
→Built scalable e-commerce backend with RESTful APIs for user authentication, product management, cart handling, and order processing.
→Implemented secure JWT-based authorization, modular architecture, and full CRUD operations with business logic separation.
→Designed relational database models and validated all API endpoints using Postman.
Employee Management System
→Built a robust HR management platform with Django and MySQL, focusing on structured data integrity and efficient record-keeping.
→Designed a relational schema to manage complex relationships between employees, departments, and payroll records.
→Leveraged Django ORM for complex queries, improving maintainability and dramatically reducing raw SQL usage.
Order Management System
→Developed a centralized platform to automate the end-to-end order lifecycle from request to fulfillment.
→Architected a relational database managing high-volume transactional data, including many-to-many relationships between Orders and Products.
Full-stack AI and modern web applications.
Task Manager
→Built a production-ready full-stack task management system with a Django REST Framework backend and React + Vite frontend, connected via JWT authentication.
→Implemented role-based access control separating Admin and User permissions, with full CRUD on tasks and a dedicated admin panel for user management.
→Containerized the entire stack using Docker and docker-compose, with Gunicorn + Nginx for production serving and Swagger / ReDoc for live API documentation.
AEO Diagnostic Tool
→Developed a Next.js application that queries Nvidia Nemotron, Gemma 3n 2B, and GPT-OSS-120B in parallel to analyze how AI answer engines mention a given product.
→Built a scoring engine that calculates a visibility score, compares competitor mentions, and generates actionable AEO recommendations rendered in a dynamic report card UI.
→Deployed on Vercel with a modular API route architecture; each AI engine has its own route, orchestrated by a single /api/diagnose endpoint for clean separation of concerns.
AI-First CRM — HCP Log
→Built a full-stack AI-first CRM prototype for logging healthcare professional (HCP) interactions, featuring a React + Vite frontend and a FastAPI backend.
→Implemented a deterministic local field extractor with LLM fallback (OpenRouter) to parse free-text interaction notes into structured CRM fields.
→Architected an async MySQL persistence layer (aiomysql) with automatic SQLite fallback for local dev, and deployed the full stack on Vercel with a clean `/api/v1` route separation between AI chat and interaction CRUD endpoints.
