Robert M.

Senior full-stack engineer with 13+ years building and shipping production web platforms end-to-end - frontend, backend, cloud, and data. I work fluently across the full stack: React, Next.js, Angular, TypeScript, and Node on the frontend and middle tiers; 𝐂#/.𝐍𝐄𝐓 and SQL/NoSQL underneath; and 𝐀𝐳𝐮𝐫𝐞, AWS, and GCP for cloud delivery. 𝐓𝐡𝐞 𝐌𝐢𝐜𝐫𝐨𝐬𝐨𝐟𝐭/.𝐍𝐄𝐓 + 𝐀𝐳𝐮𝐫𝐞 𝐞𝐜𝐨𝐬𝐲𝐬𝐭𝐞𝐦 𝐢𝐬 𝐦𝐲 𝐝𝐞𝐞𝐩𝐞𝐬𝐭 𝐬𝐩𝐞𝐜𝐢𝐚𝐥𝐭𝐲, where I bring architect-level rigor, but I've delivered complete products across many stacks, from multi-tenant SaaS and healthcare platforms to agentic AI systems and Web3 games. I've owned products from concept → production → scale across healthcare, e-commerce, energy, fintech, Web3, and consulting - as both a hands-on engineer and a founder of two companies. I specialize in modernizing legacy systems, designing secure and scalable APIs, and operationalizing LLM/agentic workflows that dramatically cut delivery time and cost. 𝐑𝐄𝐂𝐄𝐍𝐓 𝐖𝐎𝐑𝐊 - 𝐀𝐠𝐞𝐧𝐭𝐢𝐜 𝐌𝐚𝐫𝐤𝐞𝐭𝐩𝐥𝐚𝐜𝐞-𝐚𝐬-𝐚-𝐒𝐞𝐫𝐯𝐢𝐜𝐞 𝐏𝐥𝐚𝐭𝐟𝐨𝐫𝐦 - architected a multi-tenant marketplace with a React/Next.js + Node stack and integrations spanning Stripe, PayPal, eBay, OpenAI, SendGrid, Twilio, and Coinbase - deploying a working product in 2.5 months using Human-in-the-Loop agent workflows with daily security audits. - 𝐌𝐮𝐥𝐭𝐢-𝐓𝐞𝐧𝐚𝐧𝐭 𝐂𝐥𝐨𝐮𝐝 𝐄𝐌𝐑 𝐏𝐥𝐚𝐭𝐟𝐨𝐫𝐦 - built a health-protocol-agnostic EMR with an Angular + TypeScript frontend and .NET Core / Azure SQL backend, aligned with HL7 v4, FHIR R4, SMART on FHIR, Da Vinci, and US Core - leading architecture and a small team from inception. - 𝐀𝐠𝐞𝐧𝐭𝐢𝐜 𝐀𝐈 & 𝐋𝐋𝐌 𝐒𝐲𝐬𝐭𝐞𝐦𝐬 - designed multi-agent and RAG systems using OpenAI & Anthropic APIs, Azure OpenAI, vector/semantic search, Semantic Kernel, and function/tool calling, embedding LLM support into the SDLC to increase delivery velocity dramatically. - 𝐀𝐳𝐮𝐫𝐞 𝐂𝐥𝐨𝐮𝐝 & 𝐄𝐓𝐋 𝐄𝐧𝐠𝐢𝐧𝐞𝐞𝐫𝐢𝐧𝐠 (𝐄𝐱𝐱𝐨𝐧𝐌𝐨𝐛𝐢𝐥 𝐯𝐢𝐚 𝐄𝐘) - architected end-to-end pipelines in Azure Data Factory and Azure Functions across Data Lake, Blob Storage, and Azure SQL, optimizing performance across environments. - 𝐖𝐞𝐛3 / 𝐔𝐧𝐢𝐭𝐲 𝐆𝐚𝐦𝐞 (𝐒𝐨𝐥𝐢𝐜𝐞 𝐕𝐑) - contributed full-stack to a blockchain VR game using React, Unity + Unity WebGL, Rust, and smart contracts, launching three NFT rounds on Solana. - 𝐋𝐞𝐠𝐚𝐜𝐲 𝐌𝐨𝐝𝐞𝐫𝐧𝐢𝐳𝐚𝐭𝐢𝐨𝐧 & 𝐏𝐞𝐫𝐟𝐨𝐫𝐦𝐚𝐧𝐜𝐞 - migrated registration, coding, and billing apps from Web Forms / MVC to Azure-hosted .NET 8 solutions, and tuned underperforming APIs and T-SQL/LINQ workloads for measurable cost and speed gains. 𝐖𝐇𝐘 𝐌𝐄 I'm a true full-stack engineer - I design the UI, build the API, model the database, deploy to the cloud, and optimize the whole system. That breadth means I ship entire products, not just a slice. When a project demands enterprise-grade reliability and compliance (healthcare, fintech, HIPAA/FHIR), my deep .𝐍𝐄𝐓 𝐚𝐧𝐝 𝐀𝐳𝐮𝐫𝐞 specialty gives you architect-level confidence. I bring a business-focused mindset: I find ways to save executives money, modernize what's slowing teams down, mentor junior developers, and lean hard into agentic/AI-assisted development to deliver company-scale output.
