🚀 OVERVIEW I am a Senior AI Agent & Full-Stack Engineer specializing in building intelligent, production-grade software systems that combine modern web architecture with LLM-driven automation, autonomous agents, and scalable cloud infrastructure. Over the years, I’ve worked across startups, product teams, and digital agencies to design systems that don’t just function — they automate workflows, reduce operational overhead, and directly increase revenue efficiency. My core expertise sits at the intersection of AI systems engineering and full-stack product development. I build AI agents powered by OpenAI APIs, Claude, and custom orchestration pipelines that integrate seamlessly into real-world business workflows such as customer support automation, lead generation systems, document intelligence, and SaaS platforms. On the engineering side, I specialize in building scalable backend systems using Node.js, Python (FastAPI), and microservices architecture, paired with modern frontend frameworks like React and Next.js. I design systems that are cloud-native from day one, leveraging AWS, Docker, Kubernetes, and CI/CD pipelines to ensure performance, reliability, and cost efficiency. I don’t just deliver code — I deliver measurable impact: ✔ Reduced customer support workload by up to 45% through AI automation agents ✔ Built scalable SaaS platforms serving 100K+ monthly active users ✔ Improved deployment cycles by 70% using CI/CD + containerized infrastructure ✔ Designed LLM-powered workflow tools that cut manual data processing time by 80% My approach is deeply product-focused: I think in terms of business outcomes, system scalability, and maintainability rather than just features. Clients hire me when they need complex ideas transformed into stable, production-ready systems. 🧠 AREAS OF EXPERTISE ◆ AI Agent Development Designing autonomous agents using OpenAI, Claude, tool-calling frameworks, and multi-step reasoning pipelines for real business automation. ◆ Full-Stack SaaS Engineering Building complete SaaS platforms with authentication, billing, dashboards, APIs, and scalable backend architecture. ◆ LLM Integration & Automation Prompt engineering, RAG pipelines, vector databases (Pinecone, Weaviate), and workflow orchestration systems. ◆ Backend Systems Architecture Node.js, FastAPI, PostgreSQL, Redis, microservices, event-driven systems, and REST/GraphQL APIs. ◆ Cloud & DevOps Engineering AWS (Lambda, EC2, S3), Docker, Kubernetes, GitHub Actions, CI/CD pipelines, monitoring systems. ◆ Frontend Engineering React, Next.js, TypeScript, TailwindCSS, Redux, modern UI/UX architecture. ◆ Data & Automation Pipelines ETL systems, scraping pipelines, AI-powered data transformation, and real-time processing systems. 💼 PROJECT HIGHLIGHTS 🟢 AI Customer Support Agent Platform Built a multi-agent support system using OpenAI + vector search that automated 60% of incoming customer queries, reducing support costs by 40% within 3 months. 🟢 AI Lead Generation Engine Developed a full-stack scraping + enrichment + scoring system that automatically qualifies leads using LLM reasoning, increasing conversion rates by 28%. 🟢 SaaS Workflow Automation Tool Designed a cloud-native SaaS platform with Next.js + Node.js + AWS, enabling companies to automate internal workflows and reduce manual operations by 70%. 🟢 Intelligent Document Processing System Created an LLM-based pipeline that extracts, summarizes, and categorizes enterprise documents, reducing manual processing time by 80%. 🛠️ TECH STACK • Languages: JavaScript, TypeScript, Python, SQL • Frontend: React, Next.js, TailwindCSS, Redux • Backend: Node.js, FastAPI, Express.js, GraphQL • AI/ML: OpenAI API, Claude API, LangChain, RAG pipelines • Databases: PostgreSQL, MongoDB, Redis, Pinecone • Cloud: AWS (EC2, Lambda, S3), Docker, Kubernetes • DevOps: GitHub Actions, CI/CD, Nginx, Terraform basics • Tools: Stripe API, Firebase, WebSockets, Puppeteer 📩 LET’S BUILD SOMETHING POWERFUL If you're looking for a developer who understands both the engineering depth of full-stack systems and the strategic power of AI automation, I’d be glad to collaborate.

🚀 Struggling with a Shopify app that breaks across themes, slows at scale, or loses merchants during onboarding? With 7+ years building production-grade Shopify embedded apps and serverless AWS architectures, you get a full-stack engineer who ships clean code — not workarounds. 🎯 Specializing in Shopify app development using React, Remix, TypeScript, and GraphQL Admin API, combined with AWS serverless stacks (Lambda, API Gateway, Amplify, EventBridge), the focus is on what matters to your business: app stability, merchant conversion, and long-term scalability. Clients consistently see 40%+ reductions in onboarding drop-off and measurable improvements in storefront performance after a focused audit-and-refine engagement. 🛠️ Here's exactly what you can expect: • Embedded Shopify App Development (Remix + App Bridge, Theme App Extensions, OAuth flows) • Shopify GraphQL Admin & Storefront API integrations • Liquid theme compatibility and storefront widget development • Serverless backend architecture (AWS Lambda, API Gateway, DynamoDB, Kinesis, SQS) • AWS Amplify setup and CI/CD pipelines via GitHub Actions • React + TypeScript frontend development with Figma-to-code implementation • Ecommerce search, color discovery, and product filtering systems • Computer vision & AI-powered product feature integrations • Analytics dashboards, event-driven reporting, and NoSQL data modeling • Accessibility, responsive design, and cross-theme QA 📊 Past results include: rebuilding a Shopify merchant onboarding flow that cut time-to-install by 52%, migrating a REST-heavy app to GraphQL reducing API call volume by 38%, and architecting a DynamoDB-backed event pipeline handling 1M+ daily product events at sub-100ms latency. 🤝 Working directly with founders and lead engineers is a strength. Weekly sprint collaboration, async Loom updates, and clear documentation come standard — not as extras. Whether the codebase needs refinement, a new merchant-facing feature, or a production fire extinguished, the process is the same: understand the system deeply before touching a line of code. 📩 Send a message to share the current state of your platform and what's blocking your launch. A short technical discovery call is the fastest path to a clear plan of action.

That combination means I'm comfortable across the full stack and tend to think about systems as a whole rather than just the code. My work covers custom web applications, CMS platforms (headless and traditional) like PayloadCMS and WordPress, API integrations and business automation. I've built and deployed production systems for clients in tourism, digital services, civil engineering, defence and healthcare. I recently started my own company and I aim to deliver real value to business owners. That means listening carefully and giving honest advice, so that an investment actually pays off. Honesty, integrity and clear communication are things I take very seriously. I'm new to UpWork and will be working at a reduced rate while I build up my profile here.
