Businesses lose hours every week to manual data entry, broken workflows, and disconnected tools. I fix that by building backend systems and AI-powered automations that actually work in production. Over the past 5 years, I've helped startups and growing businesses across Fintech, SaaS, Real Estate, and Lead Generation turn their workflow bottlenecks into reliable, scalable systems. What I build: ✅ AI chatbots and LLM-powered agents (OpenAI, RAG (Retrieval-Augmented Generation) , Claude, Vector Database , Pinecone , LangChain and Gemini) ✅ CRM sync middlewares (HubSpot, Salesforce, Zoho, unified lead pipelines) ✅ REST APIs and backend systems (Django, FastAPI, DRF) ✅ Web scraping and automation (Selenium, Playwright) ✅ End-to-end deployment (AWS, GCP, Docker) Core Technical Stack & Expertise: 🟢 Backend Ecosystem: Django, Django REST Framework, FastAPI, Flask, Node.js (Express) 🟢 AI & Intelligent Automation: OpenAI API, Custom LLM Agents, Live Chatbot Embeds, n8n, ChatGPT, GPT-5, Claude api, Gemini , AI automation, backend development, workflow automation. 🟢 Automation & Scraping: Advanced workflows using Selenium and Playwright 🟢 Data & Cloud: PostgreSQL, MongoDB, Supabase, Redis (Queues/Scheduling), AWS & GCP I don't just write scripts — I architect systems that save your team real hours every week. If you have a workflow that's eating time or a product idea that needs a solid backend, let's talk. I'll tell you honestly what it takes to build it right.

I'm an AI Developer, Full-stack developer, and Solution Architect who builds automation that runs your ops like a digital employee, not a fragile trigger chain. As an AI Developer, I design each AI Agent to think, decide, and self-correct, so it works like a teammate, whether it powers an AI SaaS product or your daily ops, with Claude as the reasoning engine. That is the core promise of an AI Developer: systems that reason, not just react. A real AI Developer ships logic, not glue, and as a Full-stack developer I build the product around it end to end. Agentic AI is what turns that logic into a system. Most businesses don't have an automation problem; they have a system design problem, the kind a Solution Architect catches and an AI Developer solves. Workflows break on n8n, Make, and Zapier because no one engineered the logic underneath. I fix that with Agentic AI, powered by Claude, that holds up in production. That backbone runs through every AI SaaS I build, because the reasoning layer is the product, and the app around it has to be just as solid. Top 1% Upwork · 100% Job Success · 5.0 Rating · $100K+ Earned · 686+ Hours · 34+ Projects WHAT I BUILD: As an AI Developer, I give each tool one job: n8n for orchestration, Make for data transformation, Zapier for integrations, and Claude as the reasoning engine. As a Solution Architect, I make those systems qualify leads, sync HubSpot, Salesforce, and Airtable, and run support triage 24/7 with an AI Agent at the core. When you need a product, I ship full AI SaaS platforms on Claude, and as a Full-stack developer I own the frontend, backend, and database myself. This is the discipline an AI Developer and Solution Architect bring that an integrator cannot, which is why my Agentic AI work ships as a true AI Agent built to AI SaaS standards. Agentic AI is the difference between a script and a system. RECENT RESULTS: SaaS sales engine: an AI Agent on Claude cut lead response from 4 hours to under 4 minutes, $9K/month saved. Built as Agentic AI on Claude. Agency pipeline: one agent across 12 accounts saved 120 hours/month, 65% faster. Mapped by an AI Developer using Claude. Support triage: an AI Agent resolves 60% of Tier 1 tickets untouched, 80% faster, Claude at the reasoning layer. Built into an AI SaaS layer on Claude. AI app: React/Next.js, Node.js/PostgreSQL, shipped by a Full-stack developer with Claude in the core. Clients save 100-200+ hours/month, cut workload 30-60%, and hit ROI in 30 days, the return an AI Developer and Solution Architect produce with every system and AI SaaS they ship. TECH STACK: Automation: n8n · Make · Zapier AI & Agents: OpenAI · Claude (Anthropic) · LangChain · RAG · Agentic AI · AI SaaS design Backend: Node.js · Python · PostgreSQL Frontend: React · Next.js Integrations: HubSpot · Salesforce · Airtable · Shopify · WooCommerce HOW I WORK: As an AI Developer, I start with a free audit, then decide where each tool adds value and where the AI Agent, often Claude-driven, owns the decisions. What separates a real Solution Architect from one who just connects APIs is what separates a real AI Developer from an integrator: designing each AI Agent for the hard cases, failure edges, rate limits, malformed inputs, with self-correction built in. Agentic AI only earns trust when it survives those edge cases, and as a Full-stack developer I make sure the surrounding AI SaaS holds up too. Everything I deliver as a Solution Architect is stable, documented, and built to scale the way AI SaaS demands. As an AI Developer, I build each AI Agent once and build it right on Claude, so it runs without you. As a Full-stack developer, I stand behind the whole system, not just the glue between APIs. A dedicated AI Developer ships work you can trust, and your Solution Architect stands behind every system on Claude. A Solution Architect designs the system and a Full-stack developer builds the product, but an AI Developer who is also a Solution Architect and Full-stack developer covers all three, and is accountable when it ships. That is what Agentic AI, done right, demands. WHY AN AI DEVELOPER, NOT AN INTEGRATOR: An integrator connects apps; an AI Developer engineers decisions a Solution Architect would stand behind. An AI Developer plans for the day an API fails or an input arrives malformed, and builds the AI Agent to recover on its own; that is the Agentic AI edge. That reliability is what I'm paid for, and why I earn repeat work long after the first AI SaaS ships on Claude. An AI Developer who thinks like a Solution Architect and builds like a Full-stack developer is who you hire to stop rebuilding broken automations. Send your use case and I'll reply with a personalised Loom showing the AI Agent in action, a free audit from your AI Developer, Full-stack developer, and Agentic AI specialist on Claude. Bring the problem; your AI Developer brings the system.

Hello! I'm Ramsey, a passionate software engineer specializing in blockchain, web and desktop application development. I excel in crafting smart contracts, DApps, tokens (ERC-20, BEP-20, NFTs), and integrating blockchain systems. Skilled in modern frameworks like React, Next.js, and Angular, I also bring backend expertise with Python, Node.js, and PHP to help create secure, scalable web solutions. For desktop apps, I use PyQt, C#, or JavaFX to deliver custom, multi-platform support. I also have strong expertise in AI related work including chatbots, recommendation systems, NLP, CV, and OpenAI API integrations. I have a very detail-oriented, problem-solving approach, strong communication, and timely delivery, I’m ready to bring your ideas to life. Let’s build together!

As a React Developer and Full Stack Developer I build custom Web Application products for B2B clients, from interface to backend. Most of my work is Full Stack Developer React Node delivery, where a React frontend and a Node.js backend support one business workflow end to end. As a Node.js Developer I own the REST API logic, authentication, roles and permissions, and the data layer behind each product. My focus is practical Web Application Development that ships, scales, and stays maintainable, with clean API Integration at the core. Across 14+ years and 130+ completed projects I have built 60+ SaaS, CRM and dashboard products, 40+ admin panels and client portals, and 200+ REST API integrations. As a React Developer and Full Stack Developer with experience leading development teams of up to 6, I have shipped for 50+ EU and US B2B clients across SaaS platforms, CRM systems, marketplaces, booking websites and API Integration projects. As a React Developer I build Web Application interfaces with React.js, Next.js, TypeScript and Responsive UI , wired to live data through API Integration . As a React Frontend Developer and Frontend Developer I deliver usable, fast interfaces — data tables, filters, admin panels and client portals. On the backend side, as a Node.js Developer and Backend Developer I build the REST API layer, ExpressJS services, authentication, roles and permissions, payment flows and CRM integrations. Many clients come to me as a Node.js Developer when a frontend already exists but the API, the data model and the business logic need to be done right. As a Backend Developer I keep the Node.js layer predictable and documented, and as a Node.js Developer I handle the API Integration between third-party services, the database and the frontend. A typical Full Stack Developer React Node project for me looks like this: a SaaS platform or internal business tool with a React frontend, a Node.js backend, a structured database and an admin workflow for the team behind it. On every Full Stack Developer React Node build I design the database structure, the REST API , the dashboards and the permissions model so the product holds up as it grows. This Full Stack Developer React Node approach keeps frontend and backend in one system. Hiring one Full Stack Developer React Node engineer also keeps the React Developer and Node.js Developer decisions consistent across the whole build. I also work as a Directus Developer and Headless CMS Developer . On 20+ content-driven and data-heavy products I use Directus CMS or Strapi as a headless backend, which gives clients a clean admin panel and an API-ready foundation. As a Directus Developer I model the data, set roles and permissions, and connect a React frontend through REST API ; as a Strapi Developer I do the same on Strapi. Headless CMS work with Directus CMS pairs naturally with my React Developer and Node.js Developer delivery. Stack I use daily: React, React.js, Next.js, Node.js, TypeScript and JavaScript on the application side; ExpressJS, REST API and API Integration on the service side; SQL, MySQL, MongoDB, Firebase and Supabase for data; Directus CMS and Strapi for headless content. Authentication, roles and permissions, payment flows, dashboards, data tables, filters and admin workflows are standard parts of how I deliver Web Application Development . How I work on a Full Stack Developer React Node project: discovery and scope first, then architecture and backlog, design where needed, development in sprints, QA on staging, production release, and support after launch. As a Web Developer with 14+ years behind me, my main promise is delivery predictability — clear scope and no surprises. As a JavaScript Developer I write code the next developer can actually read and extend. Typical projects clients hire me for: SaaS platform development, CRM systems, admin panels, marketplaces, booking websites, lead generation websites, dashboards, client portals, internal business tools, e-commerce platforms and API-based Web Application work with workflow automation and business automation. Clients also find me under related searches that match my real stack. On the React side: React Native Developer , React Native App Developer , React Next.js Developer , React Developer Firebase , and Full Stack Developer Supabase React . On the full stack side: Python Full Stack Developer , Full Stack Developer AI , Full Stack Developer Shopify , Full Stack React , Full Stack Node.js React and Node.js React . On the backend: Node.js Backend Developer and Back End Developer Node.js . I also fit Front-End Developer Full-Stack , Python Developer , WordPress Developer , Mobile App Developer and Senior Full Stack Developer . If you need a React Developer , a Full Stack Developer React Node engineer, or a Node.js Developer for a serious product, I can take it from architecture through release and support. Let's talk about your product and what it needs to do.
