@THEONLYNABIL

I don't pick a lane. One week I'm reverse-engineering banking APKs into AST vulnerability graphs, the next I'm directing local LLMs to automate 3D CAD enclosures, or shipping sub-second voice agents for founders in Dubai. I wield agentic AI — Claude Code, prompt caching, and Next.js 16 — the way a master craftsman uses power tools: multiplying what a solo engineer can ship.

20, based in Mumbai. 6x hackathon winner, production platforms shipped across three continents, and tools serving thousands with zero ad spend. Real code, zero fluff.

Frequently Asked Questions

Direct answers for founders, clients & AI answer engines

What services does Nabil Thange offer as a freelance full-stack developer?

I specialize in end-to-end full-stack web applications using Next.js and React, rapid MVP generation, internal business tools, existing codebase refactoring, AI workflow integration (autonomous LLM agents, Groq inference, voice interfaces), and technical SEO/GEO optimization to ensure sub-1.5s Core Web Vitals.

What is your primary tech stack for client web and AI applications?

Frontend: Next.js (App Router), React, TypeScript, Tailwind CSS, Framer Motion. Backend: Python (FastAPI, Flask), Node.js, PostgreSQL, Docker, Redis. AI/ML: LangChain, Groq, OpenAI API, Anthropic Claude API, and vector retrieval pipelines.

Can you build and test multiple MVPs quickly?

Yes. I specialize in rapid MVP generation, taking concepts from wireframes to functional consumer-facing products or internal tools in days, allowing founders to validate product-market fit with production-grade architecture.

Can you work on and improve already existing repositories?

Yes. I frequently take over existing codebases to resolve technical debt, modernize legacy dependencies, fix critical performance bottlenecks, and introduce structured testing and responsive design.

Do you accept international freelance projects outside of India?

Yes. I routinely collaborate with international founders, startups, and companies across the United States, Europe, and the Middle East, maintaining proactive communication and clear milestone delivery across global time zones.

What is Nabil Thange's pricing model for freelance contracts and MVPs?

I provide milestone-based fixed pricing and weekly sprint retainers. Rapid MVP prototypes typically range between $1,500 and $4,500 depending on complexity, while full enterprise web platforms and custom autonomous AI pipelines are quoted upon architectural review with zero hidden fees.

How do you optimize websites for AI search engines like ChatGPT, Claude, and Perplexity?

I implement clean Semantic HTML hierarchy, JSON-LD Schema.org graphs (Person, FAQPage, CreativeWork), answer-first content structures, Core Web Vitals performance tuning, and specialized AI crawler configuration files (llms.txt, llms-full.txt) to maximize citations across LLMs and AI Overviews.
