AI automation engineer building n8n workflows and custom AI agents wired into real codebases - the production automation no-code tools cannot reach. 𝗧𝗼𝗽 𝗥𝗮𝘁𝗲𝗱 𝗣𝗹𝘂𝘀 on Upwork with a 𝟭𝟬𝟬% Job Success Score, $𝟭𝟬𝟬𝗞+ earned across 𝟭𝟱𝟵 contracts and 𝟰,𝟮𝟵𝟮 hours billed. ⭐ Built an n8n ERP reconciliation bot for a 𝟮𝟱𝟬+ store F&B chain: it watches the POS-to-ERP data flow, runs anomaly detection in near real time, auto-corrects, and syncs the ERP with full logging and alerting - manual reconciliation eliminated. 📈 Shipped AI automation across SaaS, EdTech, F&B, and FMCG - RAG pipelines, AI agents, and multi-step API integration that run unattended in production. 🎯 Delivered AI assignment-grading for an eLearning platform with Claude and OpenAI. Clients come back because the automation holds up. One verified 𝟱.𝟬 Upwork review: "Pranav and his team delivered an excellent job, solving the complex integration problems that multiple highly-rated Upwork freelancers chose to pass-on due to the lack of specific experience ... clear communication and project documentation enabled flawless delivery of every milestone at the highest quality." - Boris R., Verified Upwork client (5.0) That is the standard behind every automation and integration build I take on. Most automation freelancers stop where the no-code canvas ends. I start there. My background is full-stack engineering - React, Node, Python, Laravel - so I build the automation that needs real code: custom AI agents with tool use and memory, API integration into ERPs and SaaS backends, and n8n workflows hardened with error handling, retries, and monitoring. 𝗣𝗥𝗢𝗢𝗙 𝗙𝗥𝗢𝗠 𝗦𝗛𝗜𝗣𝗣𝗘𝗗 𝗪𝗢𝗥𝗞 🔹 F&B chain, 𝟮𝟱𝟬+ stores - n8n ERP reconciliation bot with anomaly detection and SQL-to-ERP sync; manual reconciliation removed. 🔹 AI web service - a client-endorsed AI automation build on a Node.js / CRACO stack, delivered as a $𝟯,𝟰𝟱𝟬 contract rated 𝟱.𝟬. 🔹 Node.js scraper and API on AWS - a $𝟮,𝟵𝟱𝟬 data-integration build, rated 𝟱.𝟬. 🔹 Trading-platform backend - a secure web panel with API integration, rated 𝟱.𝟬. 🔹 FMCG distribution - scheduled payment-reporting automation built in n8n. 🔹 eLearning platform - AI agents grading assignments with Claude and OpenAI. Every one is production automation and integration work, not a prototype - the complex automation tier, delivered. 𝗪𝗛𝗔𝗧 𝗜 𝗗𝗢 🔷 n8n Automation and Workflow Engineering Production n8n automation for real business processes: multi-step API integration, data sync, and AI-powered workflows. I wire n8n into your databases, CRMs, and private APIs, add error handling, retries, logging, and alerting, and hand off automation that runs unattended. 🔷 Custom AI Agents and LLM Integration AI agents built on Claude and OpenAI with tool use, memory, and context management: RAG pipelines, knowledge-base assistants, and AI agents that act on live business data. This is AI automation wired into your stack, not a chatbot demo. 🔷 API and System Integration The integration layer most automation needs: REST and GraphQL API integration, ERP and SaaS connectors, webhooks, and third-party services such as Stripe, Firebase, OpenAI, and Claude. I make systems that were never meant to talk to each other run as one automation. 🔷 Make and Zapier Automation When a workflow does not need a custom backend, I build it in Make or Zapier - and I choose between n8n, Make, and Zapier based on what the automation actually requires, not habit. 🔷 Productionizing and Scaling Automation Taking fragile automation to production: monitoring, logging, retry logic, and documentation so your team runs the workflow without me. Most of my work is automation that has to survive real load, real edge cases, and real data. 𝗪𝗛𝗢 𝗜 𝗪𝗢𝗥𝗞 𝗪𝗜𝗧𝗛 SaaS founders, operations teams, and agencies who have outgrown no-code automation and need it built properly: wired into real APIs and databases, hardened for production, and able to scale. If your tools do not talk to each other, your AI prototype keeps breaking in production, or a workflow that should run unattended keeps failing, or you need an automation a no-code builder cannot deliver, that is exactly where I come in. 𝗛𝗢𝗪 𝗜 𝗪𝗢𝗥𝗞 1. Map the process and the failure points before building anything. 2. Build the automation in n8n, Make, or with custom code, with error handling and logging from day one. 3. Test against real data and real edge cases, not just the happy path. 4. Hand off with documentation and monitoring so your team owns the automation. You get production automation, an API integration that holds up, and a workflow your team can run without ongoing dependency on a developer. Need an automation engineer who can take n8n, AI agents, and API integration all the way to production? Send me a message and let's scope it on a quick call.

Java sits at the center of the platforms I build. Spring Boot runs the backend services and APIs, handling business logic, data access, and the core behavior of the system. Many of these platforms pair a Spring Boot backend with Angular on the frontend, forming structured web applications such as internal dashboards, operational platforms, and SaaS systems used by teams every day. Angular provides the application interface while the Java backend manages services, data, and integrations behind the scenes. Python also comes into play when automation or data workflows are needed. Small services and scripts written in Python handle background tasks, integrations, and operational processes that support the main platform. Java and Spring Boot handle the backend services, Angular runs the platform interface, and Python supports automation and background tasks.

I build production web applications for B2B companies, full-stack web apps and MVPs that ship as working software, not slide decks. Senior Full Stack Developer focused on web application development in React/Next.js, Node, and Python/FastAPI, with Supabase/PostgreSQL on the backend and deep Claude, MCP, and OpenAI experience when a build needs AI. 126 projects, 100% Job Success, Top Rated Plus, $200K+ earned. Most companies don't need "an AI project." They need a web application that works fast, responsive, secure, and maintainable with AI layered in only where it creates real value. That's what I do: web application design and development for mid-market B2B teams, turning AI from a boardroom buzzword into production software that cuts costs, speeds up operations, and creates an edge from a clean MVP to a scalable multi-tenant SaaS platform your team can own and maintain. Not slide decks. Working software. Two ways I work with clients: → Build MVP / Web App: You know what you want a full-stack web app, a SaaS dashboard, an AI web app over your data, a client portal, or a mobile-first progressive web app. I architect it and ship it with clean, human-reviewed code, tests, and documentation. Most MVPs ship in weeks, not months. → Clarity Audit (Discovery First): Not sure where to start? I assess your product, data, and workflows, then hand you a prioritized roadmap realistic timelines, cost ranges, and the 2–3 highest-impact things to build first. What I build most often: ▪ Full-stack web application development: React/Next.js, Node, Python/FastAPI, Supabase, PostgreSQL, AWS, Docker ▪ SaaS platforms, MVPs & web apps: Multi-tenant architecture, authentication, role-based access, Stripe billing, admin dashboards, responsive UI ▪ Web app design & UI/UX: Modern, conversion-focused web application design, from wireframe to production (UI/UX web app builds); your web application designer and web app developer in one ▪ Progressive web apps: Installable, mobile-first progressive web apps (PWA) that feel native without an app-store build ▪ AI web apps: RAG systems, LLM-powered features, and Claude/OpenAI integrations built directly into the product ▪ Also, when a web app needs it: AI agents, MCP server integrations, and workflow automation (n8n, Make, Zapier) ▪ API development & integrations: REST APIs, third-party services, webhooks, and Stripe. How I work: AI-accelerated but human-led. I use modern tooling (Claude Code, Cursor) to move fast, but every web application ships with tests, documentation, and code a senior engineer would sign off on —speed and maintainability, not throwaway scripts. Clients who've been burned by page-builder or no-code builds hire me to rebuild it properly as a real web application in React/Next.js. Where I've delivered: 126 Upwork projects across EdTech, Pharma, Real Estate, Logistics, Financial Services, and CRM/ERP platforms as a full stack developer and web application designer on each. Send a message with your goal. On a quick call I'll tell you within 30 minutes whether you need a web app developer for a fixed-scope build or a Clarity Audit for larger work.

🥇 Top Rated Plus | 41+ Jobs Completed | 3,200+ Hours | 100% Job Success I'm Syed Umair, a senior mobile app developer with 9+ years of experience building and hardening production apps in Flutter and React Native. Clients come to me for two things: building solid mobile apps from scratch, and honestly telling them what's broken, unfinished, or risky in apps they already have. I don't sugarcoat audits, if something isn't production-ready, I'll say so clearly and back it up with evidence. WHAT I DO: 📱 Mobile App Development Custom Flutter & React Native apps for iOS and Android, from idea to App Store launch. Clean architecture, maintainable code, real production readiness (not just "it works on my machine"). 🔍 Code & Production-Readiness Audits I review existing Flutter/React Native + Laravel/Node/Firebase codebases and give you a clear, prioritized verdict: what's a launch blocker, what's safe for beta, what's just technical debt. Non-technical founders especially value this, I explain everything in plain language. 🔗 Backend & Integrations Laravel, Node.js, and Firebase backends. Stripe payment integration (subscriptions, auto-charges, webhooks, refund/failure handling), Google Maps/Navigation SDKs, real-time features (WebSockets/Firebase). 🚀 App Store & Launch Support In-app purchase setup, App Store/Play Store submission, and post-launch troubleshooting. WHY CLIENTS WORK WITH ME: ✔ Direct, honest technical judgment, I tell you what's actually true, not what's easiest to hear ✔ Clear communication tailored for both technical and non-technical founders ✔ Strong track record auditing and hardening apps others built ✔ Full-cycle: architecture review → development → integration → launch TOOLS & TECH: Frontend: Flutter, React Native, Kotlin (native Android) Backend: Laravel, Node.js, Firebase Payments: Stripe (webhooks, subscriptions, auto-billing) Other: Google Maps/Navigation SDK, TestFlight, App Store/Play Store submission Have an app that needs to get built right, or an existing app you're not sure is really production-ready?
