Adnan A.

I have delivered 40+ large scale web platforms and enterprise applications, working across complex architectures, real-time systems, SaaS, financial platforms, LMS, and AI products. I develop production-ready AI web applications, LLM/RAG systems, AI agents, business automations, and SaaS platforms using Python, FastAPI, PHP, Laravel, Node.js, React, Vue.js, Next.js, and modern AI APIs. I specialize in developing production systems with advanced AI integrations including LLMs, RAG, AI agents, automation, intelligent workflows, and API-driven architectures. I am a Senior Full Stack Developer with 7+ years of experience developing AI products, SaaS platforms, trading systems, LMS solutions, and enterprise applications. I handle the complete product lifecycle from architecture and AI integration to backend APIs, frontend development, databases, automation, cloud deployment, and optimization. Core Expertise: AI Applications & LLM Integration: OpenAI, Claude, prompt engineering, structured outputs, AI workflows RAG & Knowledge Systems: embeddings, vector search, document processing, semantic search, AI knowledge bases AI Agents & Automation: AI agents, workflow automation, n8n, API orchestration, multi-step business processes SaaS Development: multi-tenant platforms, subscriptions, Stripe, dashboards, authentication, role based access Full Stack Engineering: PHP, Laravel, Python, FastAPI, Node.js, React, Vue.js, Next.js, TypeScript, REST APIs, PostgreSQL Production Systems: real time applications, third-party integrations, background jobs, testing, deployment, and performance optimization What I Develop: AI SaaS platforms and MVPs LLM and RAG applications AI agents and business automation systems AI knowledge bases and document intelligence platforms Internal AI tools and operational dashboards API driven web applications and third-party integrations Trading and financial analytics platforms LMS and enterprise business applications Selected Experience I have worked on real-world products involving AI SaaS, financial systems, real-time data pipelines, workflow automation, LMS platforms, ecommerce, and custom business applications. One example is SweepAlgo, a trading SaaS platform involving complex financial calculations, real-time data pipelines, dashboards, and full-stack architecture. I’ve also worked on AI SaaS products involving AI content generation, AI editing workflows, publishing, subscriptions, custom domains, and production-ready web applications. My focus is not simply connecting an AI API to an application. I develop the complete system around the AI, including reliable backend architecture, data processing, validation, automation, user experience, security, scalability, and maintainability.
