You will get Web app development using React, Next.js, Python, Django


Project details
Hi 👋🏻, I'm Sarthak, a Full-Stack Developer specializing in Python, Django, FastAPI, Flask, React, and Next.js. I help startups and businesses build secure, scalable, and high-performance web applications from MVPs and internal tools to SaaS platforms and business applications.
Whether you need a new application built from scratch or want to improve an existing one, I can help with backend development, full-stack web applications, REST APIs, database design, authentication, third-party integrations, and business logic tailored to your requirements.
My experience includes building SaaS platforms, admin dashboards, CRM systems, booking platforms, eCommerce applications, and internal business tools, delivering complete solutions with a Python backend and React/Next.js frontend.
What you can expect:
• Python backend with Django, FastAPI, or Flask
• Full-stack development with React & Next.js
• REST API development and integrations
• Database design and authentication
• Third-party API integrations
• Scalable and maintainable architecture

As a Python backend developer, I build scalable systems, REST APIs, databases, and production-ready backend architectures using Django, FastAPI, and Flask. My experience includes developing backend systems for SaaS platforms, admin panels, dashboards, CRM systems, booking platforms, eCommerce solutions, internal business tools, and automation applications.
On the AI side, I develop LLM-powered applications, RAG systems, document processing pipelines, and automation workflows. The goal is to make AI practical and usable inside real backend systems, not just experimental features.
I also build full-stack web applications using React, Next.js, PHP, and Python, developing SaaS platforms, dashboards, and internal tools with a focus on scalability, performance, and maintainability.
Alongside backend and AI work, I have experience in machine learning and data science, including predictive modeling, data pipelines, and data-driven insights.
I enjoy solving technical challenges, whether it's designing a new backend architecture, improving an existing application, integrating AI capabilities, or optimizing system performance. My goal is always to build software that is clean, maintainable, and ready for long-term growth.
