You will get a custom web platform or cross-platform mobile application
Project details
Need a custom digital product built right the first time? I engineer high-performance web platforms and cross-platform mobile applications from the ground up, ensuring your systems are fast, secure, and ready to scale.
What this project offers:
• Modern Web Development using industry standards like React and Next.js.
• Smooth Cross-Platform Mobile Apps built via React Native or Flutter.
• Scalable Backend infrastructure (Node.js, Python, PostgreSQL, Supabase).
• Secure database architecture with row-level security and optimal query speeds.
• Essential production integrations: Authentication, payment gateways, and APIs.
By bridging clean frontend interfaces with solid backend infrastructure, I build complete, production-grade applications. Whether you need a user-facing mobile app, an internal corporate web portal, or a unified multiplatform system, I deliver clean, documented code built for growth.

Develop a robust and scalable backend system to support the operations of a sportsbook and casino
I had really nice and satisfactory experience working with Vaibhav. Very quick and quality work. Also got nice suggestions from him, related to log term maintenance cost and scalability. Seems like they do have really good experience in this domain. I do have couple of new things in pipeline, I will sure hire Vaibhav going forward.

I work across two core areas:
• Mobile Development - cross-platform apps built with React Native and Flutter that feel native, perform fast, and scale with your user base.
• AI & Intelligent Systems - RAG pipelines, LLM integrations, and autonomous agents built for real business use cases, not just demos.
In 2026, most products need both. A mobile app with an AI layer is no longer a differentiator - it's the baseline. I build systems where both sides work together cleanly.
► What I Build
• React Native & Flutter apps (iOS + Android)
• RAG systems with document intelligence and semantic search
• LLM-powered agents using OpenAI, Claude, and Gemini APIs
• Anthropic API & OpenAI API integrations
• Vector database implementations (Pinecone, Weaviate, ChromaDB)
• LangChain & LlamaIndex pipelines
• Backend APIs with Node.js and Python
• App architecture, code reviews, and technical consulting
► whom I Work With
Startups building their first AI-native product, product companies adding intelligence to existing mobile apps, enterprise teams that need a senior technical partner - not just a developer who executes tickets.
► How I Engage
• Discovery & Architecture Review
• MVP Development & Launch
• AI Feature Integration into Existing Products
• Long-term Development & Scaling Support
If you're building a mobile or AI product with a clear goal and need someone who can think at the architecture level and execute at the code level, message me with what you're building, and I'll tell you honestly if and how I can help.
