Project details
Add a production-quality AI assistant to your product without hiring an AI team. I integrate Claude or GPT into your existing web or mobile app: a chat UI that matches your brand, a secure backend API, prompt design tuned to your use case, and optional RAG so the assistant answers from your own docs and data.
I'm a Top Rated Plus engineer ($1M+ earned on Upwork, 19 years of experience) and co-founder of Nerddevs. We shipped AI Mate and Genius, AI assistant apps used by 100,000+ people, and TissueConnect.ai, an Azure-based medical imaging AI platform.
Your assistant ships with error handling, rate-limit protection, and cost monitoring, deployed to your AWS or Azure environment. You own all source code.

Production LLM apps: chat assistants, RAG pipelines, and AI agents built on OpenAI and Claude (Anthropic) APIs. Shipped work includes AI Mate and Genius (AI assistants) and TissueConnect.ai, an Azure-based medical imaging AI platform.
𝐇𝐞𝐚𝐥𝐭𝐡𝐓𝐞𝐜𝐡, 𝐅𝐇𝐈𝐑 & 𝐇𝐈𝐏𝐀𝐀
I implement HL7 FHIR for interoperable exchange of patient and clinical data with EHR systems, with HIPAA-compliant handling of protected health information end to end. On TissueConnect.ai I built FHIR integration into an Azure-based medical imaging AI platform.
𝐑𝐞𝐚𝐥-𝐓𝐢𝐦𝐞 𝐕𝐢𝐝𝐞𝐨 & 𝐖𝐞𝐛𝐑𝐓𝐂
Low-latency WebRTC is a core strength: telehealth consults, live classes, remote proctoring, and synchronized multi-party sessions. I built Daency, where every student in a class follows the same video in real time with their trainer.
𝐂𝐥𝐨𝐮𝐝, 𝐃𝐞𝐯𝐎𝐩𝐬 & 𝐋𝐨𝐚𝐝 𝐁𝐚𝐥𝐚𝐧𝐜𝐢𝐧𝐠
AWS (EC2, S3, Lambda, VPC, Route53, CloudFront, ALB/NLB), Azure, Google Cloud, DigitalOcean. Load balancing, auto-scaling, NGINX, Docker, CI/CD (GitHub Actions, Jenkins). I've run infrastructure for an SMS platform handling millions of texts a month, and high-stakes online exams that cannot go down.
𝐅𝐮𝐥𝐥 𝐒𝐭𝐚𝐜𝐤 & 𝐌𝐨𝐛𝐢𝐥𝐞
TypeScript, React, Next.js, Vue, Node.js. REST and GraphQL APIs backed by MongoDB, PostgreSQL, MySQL, and Redis. Mobile and desktop with Flutter, React Native, and Electron.
𝐀𝐫𝐜𝐡𝐢𝐭𝐞𝐜𝐭𝐮𝐫𝐞 𝐚𝐭 𝐒𝐜𝐚𝐥𝐞
Software architect for TestReach since 2014, an online assessment and remote proctoring platform used by leading certification bodies. Co-founder of NerdDevs (20+ engineers), so when your project needs more than one pair of hands, I can bring a vetted team.
