What I'm looking for

I’m actively seeking remote software engineering roles where I can ship production SaaS with strong engineering practices—full-stack development plus RAG/LLM features, clean APIs, and reliable deployment/CI/CD.

I’m a Full Stack and AI/ML Developer focused on building production-grade SaaS platforms, RAG pipelines, and LLM-powered applications. As an intern at RISETECH Pvt. Ltd., I built scalable MERN stack applications with third-party REST API integrations, React.js UI components, and Node.js/Express.js routes following an Agile methodology.

I’ve shipped end-to-end projects like PrepifyAI, a RAG-based chatbot for Pakistani matriculation exam prep with DistilBERT topic prediction and semantic MCQ generation, and DevScope AI, a multi-tenant indexing platform with streaming Q&A, auto docs, PR review automation, and task scoring deployed on Railway + Vercel. I also build AI compliance copilots (MedLaw) and security-focused systems like an E2EE messaging platform with AES-256-GCM, RSA/ECC, and STRIDE threat modeling.
