Chandani R.

Senior full stack and AI developer for web apps, SaaS platforms and business websites. I build the backend and the screens together, from scalable, event-driven APIs in Python (FastAPI, Django) or PHP (Laravel) to React or Next.js on the front end, and add AI features (assistants, smart search and generated content) inside the product. I've built for the web for 7+ years, the last five at Coretus Technologies on SaaS and AI products, working alongside frontend, AI and QA engineers. ◆ PYTHON BACKENDS: FASTAPI & DJANGO REST and GraphQL APIs, authentication and roles, PostgreSQL, MySQL and MongoDB data models, vector databases for AI search, background jobs, payments and third-party integrations, built to be fast, tested and easy to extend. ◆ PHP & LARAVEL APPLICATIONS Laravel web apps, APIs and admin panels: new builds, new features in existing apps, upgrades and bug fixes without breaking what already works. ◆ SCALABLE BACKENDS & EVENT-DRIVEN ARCHITECTURE Services that keep working as traffic and data grow: event-driven architecture with Kafka, service-to-service communication with gRPC, GraphQL APIs for flexible frontends, and background processing that keeps the app fast for users. ◆ AI FEATURES IN YOUR PRODUCT Assistants, smart search over your own documents and generated content, built on LLM APIs and vector databases (pgvector, Pinecone) behind clean FastAPI services, so AI works inside your real product rather than a demo. ◆ FULL-STACK WEB APPS & SAAS End to end, from database and API to responsive React or Next.js screens: dashboards, customer portals, booking systems and marketplaces. ◆ WORDPRESS, WOOCOMMERCE & SHOPIFY Business websites and online stores done properly: custom themes and plugins, WooCommerce and Shopify stores, payment and shipping setup, and integrations with your other systems.

HOW WE'D WORK You get a link to try every week, not just screenshots, and I'm happy to start with a small paid task so you can see how I work first.
