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.

End-to-end execution covers the entire pipeline, from initial system architecture and Node.js/Python backend code to React Native frontends and App Store publishing.
Whether you're a founder launching an MVP or an engineering team scaling an existing platform, you get production-ready software shipped at maximum velocity.
► Core Engineering Focus
• Full-Stack SaaS & Web Applications: Multi-tenant SaaS architectures, custom web platforms, admin portals, and secure API backends built with Node.js, Python, TypeScript, and React.
• Cross-Platform Mobile Engineering: High-performance iOS and Android apps using React Native and Flutter. Native feel, offline-first sync, payment processing, and store release pipelines.
• Applied AI & Intelligent Systems: Production RAG pipelines, custom LLM integrations (OpenAI, Claude, Gemini), semantic vector search, and autonomous workflow agents built into web and mobile UIs.
► High-Velocity Engineering Workflow
To build fast without creating messy code or technical debt, I integrate modern AI tools into my daily development process:
• System Specs & Logic: Using Claude to convert raw inputs into structured architecture docs, user flows, and edge-case mapping before writing code.
• Rapid UI & Backend Scaffolding: Utilizing tools like Emergent and Antigravity to quickly build clean foundational bases.
• Core Engineering: Writing production-ready logic, custom integrations, and complex features using Cursor for speed and precision.
• Key Features & Payments: Implementing Stripe billing, secure auth, real-time WebSockets, and operational admin panels.
• Testing & QA: Automated test-case generation with Cursor to catch bugs before production releases.
• Clean Handover: Full technical documentation generated via Cursor and Windsurf so your team can maintain the codebase easily.
► Technical Toolkit
• Full-Stack & Web: React, Next.js, Node.js, Python (FastAPI/Django), TypeScript, REST APIs, GraphQL
• Mobile: React Native, Flutter, iOS, Android, Redux, Zustand
• AI Stack & Tools: Cursor, Claude, Windsurf, LangChain, LlamaIndex, OpenAI & Anthropic APIs, Vector DBs (Pinecone, ChromaDB)
• Databases & Cloud: PostgreSQL, MongoDB, Redis, AWS, Firebase, Docker
► Domain & Industry Experience
HealthTech (HIPAA compliance), EdTech, E-Commerce & Multi-Vendor Marketplaces, Social & Community Platforms.
