I am an experienced Mulesoft developer with a strong background in Java EE. With over 15 years of industry experience, I have successfully delivered numerous integration projects and possess a deep understanding of enterprise-level application development.

I help companies build software that is difficult to build. With 20+ years of hands-on engineering experience—including CTO and Head of Engineering roles—I design, build, modernize, and scale complex software products. I've worked with startups, fast-growing SaaS companies, trading firms, and enterprise organizations, leading projects from idea to production. My experience includes AI-powered applications, trading and fintech platforms, SaaS products, cloud-native systems, backend architecture, automation, and engineering leadership. I still write production code every day and enjoy solving challenging technical problems. Whether you need an MVP, a production-ready platform, AI integration, system modernization, performance optimization, or technical leadership, I can take ownership of the entire engineering process—from architecture and implementation to delivery. Core expertise: • AI Agents, LLMs & Automation • Trading & FinTech Systems (FIX, Market Data, Risk) • SaaS Platforms & Cloud Architecture • Java, Python, Node.js, TypeScript • AWS, Docker, Kubernetes, PostgreSQL • CTO / Fractional CTO / Engineering Leadership I prefer long-term partnerships where I can make a measurable technical and business impact.

I build production-ready web apps and AI features that ship fast and don’t break in production. RAG chatbots, AI agents, LLM integrations, and full-stack delivery (Spring Boot + React/Next.js + Node/Python). Top Rated | 100% Job Success Hi, I’m Muneeb, a Full-Stack Engineer specializing in AI integrations (LLMs, RAG, Agents) and scalable web apps. I help startups and product teams ship clean, fast, production-ready features from MVP to mature systems without hand-holding. What I build (client outcomes) LLM features inside your product: summarize, extract, classify, chat, search, Q&A RAG chatbots (secure, multi-tenant, citations, evals, monitoring) AI agents & tool-using workflows (guardrails, retries, structured outputs) Full-stack SaaS features (auth, billing, dashboards, APIs, admin panels) Automation + integrations (OAuth, 3rd-party APIs, Twilio, webhooks, event-driven flows) Performance & reliability fixes (slow endpoints, query tuning, memory leaks, flaky UI) My core stack Frontend: React, Next.js, Angular, TypeScript, Tailwind, shadcn/ui Backend: Java (Spring Boot), Node.js (NestJS), Python, REST APIs AI/LLM: RAG, AI Agents, prompt engineering, LangChain/LangSmith, Claude/Gemini (as needed) Data: PostgreSQL, MySQL, MongoDB DevOps: Docker, Git, CI/CD (GitHub Actions/Jenkins) How I work * Clarify scope + success criteria (fast) * Ship an MVP version early (so you can test) * Iterate with tight feedback loops * Handover with clean code + docs + deployment notes If you want someone who can own a feature end-to-end and deliver reliably, message me with: your goal, your current stack, and what “done” looks like.
