New product hardware design (concept to production-ready PCB) • Architecture and block diagrams for your electronics (MCU, power, interfaces, connectivity) • Schematic design and capture in Altium Designer (or KiCad/Eagle on request) • Multilayer PCB layout with controlled impedance, length matching, and proper grounding • Design for manufacturability (DFM) so your CM can build and test boards smoothly 2. PCB review, cost-down and reliability upgrade Already have a design? I can: • Review your schematic and PCB layout for signal integrity, power integrity, and EMI/EMC risks • Reduce BOM and PCB cost (alternative components, better stack-up, optimized routing) • Improve thermal behavior and reliability for 24/7 operation in real environments • Help you move from “prototype that works on the bench” to “design that works in production” 3. Compliance-conscious, production-focused design • Design practices aligned with EMI/EMC, CE, UL and CISPR requirements • Grounding, filtering, shielding and layout strategies to avoid surprises in the test lab • Clean documentation: schematics, PCB files, Gerbers, fabrication/assembly outputs, PDFs, BOMs ✅Recent project highlights • Designed an ESP32-based LoRa IoT sensor node with RS485/Modbus interface for industrial monitoring. Created a 4-layer Altium PCB optimized for low power, robust EMC behavior, and easy enclosure integration. • Developed an STM32-based industrial controller board with isolated digital inputs/outputs, 24 V power domains, and RS485/CAN communication. The hardware was taken from concept to tested prototype and prepared for volume manufacturing. • Reviewed and cost-optimized an existing ESP32 control board, replacing hard-to-source parts, simplifying the power stage, and reducing BOM cost by ~25% while improving thermal margins and layout quality. • Designed a Raspberry Pi-compatible expansion HAT with LoRa communication, environmental sensing, relay output and RGB indication. Delivered complete Altium design, manufacturing files, and test guidance for small-batch production. • Created a high-voltage/power PCB with isolated gate drivers, current sensing, and careful creepage/clearance management. Layout was done with EMI/EMC and safety in mind to support future certification. ✅Tools, technologies and platforms • Primary CAD: Altium Designer (main tool for professional work) • Also experienced with: KiCad, Eagle, EasyEDA, Proteus • MCUs: ESP32, ESP8266, STM32, NXP, TI and similar 32-bit controllers • Interfaces: RS485, Modbus, CAN, Ethernet, SPI, I2C, UART, USB • Wireless: Wi-Fi, BLE, LoRa (module-based designs) • Applications: IoT devices, industrial controllers, sensor boards, data loggers, power electronics, battery-powered products ✅How I work • Hardware-first mindset: I focus on solid electronics architecture and PCB design; I can support basic firmware bring-up and collaborate closely with your firmware/software team. • Clear communication: upfront questions, regular updates, and intermediate design reviews so there are no surprises. • Production thinking: I design as if your board will go to manufacturing – even if you’re only building 5–10 units today. If you need a reliable hardware partner to design, review or optimize your PCB for a real product (not just a one-off hobby build), send me a message with a short description of your project, current status, and timeline. Let’s see how we can get your hardware ready for the field.

Hi! I'm Muhammad, a full-stack developer with 6+ years building SaaS products with real product logic: billing, roles, dashboards, CRMs, messaging, APIs, reports, and AI-powered workflows. I build and repair React, Next.js, Node.js, Express, NestJS, MongoDB, PostgreSQL, Supabase, and TypeScript apps that need to hold up in production. Most developers can build screens. The harder part is building the system behind those screens: the data model, user permissions, payment flow, admin logic, API structure, third-party integrations, AI features, deployment setup, and the edge cases that show up after real users start using the product. Results That Speak: - 6+ years of experience - Top Rated Plus (React | Next.js | Node | AI Integration) - 5 Star client reviews for speed, reliability & communication - 6,000+ hours logged | $300k+ earned | 100+ projects delivered That's where I usually fit in. I work best on SaaS platforms, AI-powered tools, internal dashboards, CRMs, marketplaces, booking systems, real-time apps, and web/mobile products where the application is more than a basic frontend. The kind of problems I handle: - Turning a rough SaaS idea into a working MVP with frontend, backend, database, auth, payments, and deployment - Cleaning up React or Next.js apps that became hard to maintain - Fixing slow dashboards, broken APIs, unstable database queries, Stripe issues, auth bugs, and deployment failures - Building admin panels, user roles, subscription flows, notifications, messaging, reporting, and workflow automation - Integrating Stripe, Stripe Connect, Twilio, Google Maps, Firebase, OAuth, JWT, webhooks, and custom APIs - Adding real AI features (OpenAI, Claude, Gemini, RAG pipelines, MCP, agents) where they make the product more useful, not just because "AI" sounds good Recent product work includes: - Averi AI - AI marketing SaaS built with Next.js, PostgreSQL, and AI integration. Led engineering and helped raise $5M seed funding. - Autobunny - platform for car dealerships that reduced manual dealer tasks by 60%. - Westepforward - AI-based EdTech exam prep platform with real-time analytics and admin tools. - Chlk - Fabric.js / Konva.js canvas app built for NFL coaches with rich play-design features that cut design time by 50%. - Traceo - browser-based bug capture tool for dev and QA teams (Co-Founder & CEO). Built on Next.js, NestJS, and Supabase with a Chrome extension and AI-assisted reporting. Tech I use Daily: - Frontend: React.js, Next.js, Tailwind, Fabric.js, HTML/CSS - Backend: Node.js, NestJS, Express, GraphQL, REST - Databases: MongoDB, PostgreSQL, Supabase, DynamoDB - Mobile/Desktop: React Native, Electron.js - Cloud & DevOps: Vercel, AWS, Heroku, Hostinger - AI Tools: OpenAI (GPT-4), VAPI, Claude, Together.ai, LangChain, n8n When I start on a project, I don't jump straight into code. I first look at the product goal, user roles, database structure, API flow, payment logic, integrations, and deployment plan. Bad architecture early usually turns into expensive cleanup later, so I prefer building it correctly from the start. I'm a strong fit if you need a developer who can take ownership of a real product, make technical decisions, and ship AI SaaS features that work beyond the demo stage. Send me your app details, current stack, and what needs to be built or fixed. I'll respond with a practical technical plan.

Healthcare process automation with HIPAA-aligned data handling. Models built to live in real environments, not notebooks. 𝗔𝗴𝗲𝗻𝘁𝗶𝗰 𝗟𝗟𝗠 𝗪𝗼𝗿𝗸𝗳𝗹𝗼𝘄𝘀 (𝗖𝗹𝗮𝘂𝗱𝗲, 𝗢𝗽𝗲𝗻𝗔𝗜, 𝗺𝘂𝗹𝘁𝗶-𝗺𝗼𝗱𝗲𝗹) End-to-end AI agents shipped to production: a Shopify + Amazon SP-API customer service agent with order lookup, refunds, returnless-refund policies, Slack/Email approval gates, and Klaviyo sync. Multi-step LLM pipelines with tool use, RAG, function calling, and human-in-the-loop checkpoints. I design these as systems, not single prompts, and I'm comfortable across Claude, OpenAI, and open-weight models depending on what fits the workload. 𝗙𝘂𝗹𝗹-𝗦𝘁𝗮𝗰𝗸 𝗙𝗼𝘂𝗻𝗱𝗮𝘁𝗶𝗼𝗻𝘀 Every AI product needs scaffolding that holds. I've shipped Django/Node/React/Next.js platforms that ran 3+ years in production, Alchemist Real Estate, audIT.app, and a long-running B2B SaaS that grew from MVP to hundreds of users across $195K+ in contracted development. Distributed backends, REST/GraphQL APIs, AWS-native deployment, data pipelines, and the DevOps to keep them stable. 𝗛𝗼𝘄 𝗜 𝘄𝗼𝗿𝗸 As Lead Engineering Architect, I stay hands-on through the whole lifecycle, discovery, architecture, core implementation, deployment, and the long tail. I don't hand off and disappear. Most of my Upwork work is repeat business or long contracts measured in years, not weeks. If you're building a Voice AI agent, a computer vision platform, an LLM-driven workflow, or a full-stack AI product that needs to survive real load - let's talk.

Your support team answers the same questions every day, and a generic bot only makes it worse. I fix that as an AI Chatbot Developer, AI Engineer, and System Architect: a chatbot built on your real data with Agentic RAG and AI LLM orchestration, engineered in Python, gives accurate, source-cited answers 24/7, with no human intervention. That is the difference between a real chatbot and a demo, and it is what an AI Engineer designs every Python system to deliver. Top Rated AI Chatbot Developer and AI Engineer on Upwork · 50+ AI Chatbot systems in Python · 10+ years software engineering · 100% Job Success · $100K+ earned across healthcare, finance, SaaS, and real estate. The principle behind every build: a chatbot that isn't grounded in your knowledge base is just a science project. So as an AI Engineer and System Architect, I ground each chatbot in your actual documents and databases with Python, and I tune the Agentic RAG layer in Python until the AI LLM answers from your data, not from guesswork. Deep AI LLM tuning is where an AI Engineer earns the result. What I build: Agentic RAG chatbots context-aware chatbot answers drawn from your own documents over Pinecone, Qdrant, or Chroma, on Claude, GPT-4, or Llama 3, wired together in Python. Sources cited, no hallucinations, every AI LLM answer grounded in your data by an AI Engineer. AI LLM-powered workflows Python with LangChain and LlamaIndex that read documents, extract insights, and automate multi-step work end to end, with AI LLM retries and exception handling in Python. Engineered by an AI Engineer and architected by a System Architect, with the chatbot layer sitting on a scalable Python core. GenAI & NLP apps a text, voice, and image chatbot with full conversation state and multi-platform deployment, shipped end to end in Python by a System Architect. Healthcare & telehealth HIPAA-compliant Agentic RAG chatbot pipelines with strict data grounding and audit trails, built in Python by an AI Engineer and System Architect with real healthcare experience. Rapid MVPs a working chatbot in weeks, not months, delivered as clean, documented Python your team can own as a maintainable Python asset. That is how an AI Engineer builds a Python chatbot to hand off. Results: support costs cut 35-55% with an Agentic RAG chatbot · 100+ hours/month recovered through AI LLM automation in Python · up to 60% revenue lift from smarter chatbot engagement. These are the numbers an AI Engineer and System Architect are hired to move. How I work: Discovery, then Agentic RAG and AI LLM architecture in Python, then a fast MVP, then scaling for accuracy, speed, and multi-platform deployment. Because I work across every major AI LLM and open-source AI LLM provider through Python, I'll tell you honestly whether Claude, GPT-4, or open-source fits your accuracy, cost, and privacy needs before you commit. What separates a real System Architect from an API-wrapper is designing each chatbot for real data, real edge cases, and real production load in Python, the standard an AI Engineer is held to across every AI LLM I deploy. Scalability and infrastructure: a chatbot that's fast in a demo and slow under load is a failure, so as a System Architect I design the data flow, caching, and failover in Python that keep your chatbot fast at scale. An AI Engineer plans the Python system before a line of code ships, and a System Architect owns the trade-offs between cost, latency, and accuracy. That architecture-first discipline is what a System Architect brings that an integrator cannot. Tech stack: Python · Claude · GPT-4 · Llama 3 · LangChain · LlamaIndex · AutoGPT · Autogen · Pinecone · Qdrant · Chroma · Node.js · Django · TensorFlow · Docker · AWS · Azure, the Python toolkit an AI Engineer ships with. Want a chatbot or Python product that's measurable, not a science project? Message an AI Engineer and System Architect who has shipped 50+ Python chatbot systems. As your dedicated AI Chatbot Developer, AI Engineer, and System Architect, I offer a free 30-minute consultation to map your Agentic RAG and AI LLM roadmap in Python before you spend a dollar on your build, scoped by a System Architect. Bring your use case and a System Architect who grounds every chatbot in real data and clean Python will scope it properly. That is the commitment a System Architect stands behind, and the reason a grounded chatbot earns the contract.
