Most AI integrations don't fail because of the model. They fail because the system around it wasn't engineered for production. Wrong state management. Fragile tool calls. A frontend that looks good but doesn't reflect what's actually happening in the backend. An AI that works in isolation and falls apart the moment it has to call real tools, sync real data, and make real decisions under load. I've spent four years closing that gap. I build full-stack AI systems end-to-end: backend, frontend, AI agents, APIs, and the infrastructure that holds everything together when real users hit it at scale. Production platforms I've shipped are handling thousands of real interactions daily across voice, email, chat, and CRM. The kind of systems that still work at 11pm on a Sunday when nobody's watching. At Rawk.ai, I built the backend infrastructure and cut average voice response latency from 900ms to 320ms. At VoiceCake, I was the core developer, built the full agent pipeline, booking system, UI, and CRM integrations across HubSpot, Salesforce, Zoho, and clinic EMR systems. Dynaris is an AI front desk platform I built for multi-location businesses handling inbound leads across voice, email, and chat with automated qualification and real-time CRM sync. Deployed live across healthcare, dental, real estate, home services, mortgage, and e-commerce. Core Stack Python and FastAPI for backend systems and APIs. React for frontend interfaces and dashboards. LangChain and LangGraph for multi-step AI orchestration, tool calling, memory management, and autonomous decision-making. Vapi, Retell AI, Twilio, and WebRTC for voice pipelines with sub-500ms latency. RAG systems using Pinecone, FAISS, and ChromaDB. CRM integrations with HubSpot, Salesforce, Zoho, Google Calendar, and custom APIs. Multi-channel automation across voice, SMS, WhatsApp, email, and web chat. GDPR and HIPAA-compliant builds for healthcare and dental clients. How I Work The part most developers underestimate is not the model, it is everything around it. State management, API reliability, latency under load, fallback behavior, CRM sync that actually works, and a frontend that gives your team real visibility into what the system is doing. That is where production systems succeed or fall apart. I have been the person who owns the spec, not just implements it. Clean architecture, documented handoffs, real latency targets, and systems built to scale beyond the demo. I do not use no-code builders or drag-and-drop tools. Everything I build is engineered for production, maintainable, and built to hold up under real usage. Let's Talk If you are building an AI-powered product, integrating AI into an existing system, or replacing manual workflows with something that actually scales, send me your current stack and use case. I will tell you exactly what it takes to ship it properly.

I'm a backend Python developer with a strong foundation in mathematics, machine learning, and problem-solving. I currently work as a subject matter expert in math, where I design complex prompts for large language models and write detailed, step-by-step technical solutions--experience that's made me exceptionally good at explaining and implementing technical ideas clearly and precisely. I'm now applying those same skills to software development, focusing on machine learning-driven backend systems. My recent projects and accomplishments include the following: - FastAPI web app that serves a trained MNIST digit classifier, using Docker for containerization. - Image-to-image translator (CycleGAN) capable of style transfer between two visual domains. - C++ web server with Websock2, complete with a database backend and an interactive, dynamically-generated maze frontend in JavaScript. - Kaggle certificates in Deep Learning and Computer Vision. Core skills: - Python (FastAPI, TensorFlow, Keras, NumPy, Pandas) - Machine Learning & Deep Learning - API development & automation - Linux & Bash - Docker & deployment - C++ and JavaScript - Technical writing & documentation I'm motivated by building things that work--turning data and algorithms into functioning products. If you need a developer who learns fast, communicates clearly, and can integrate machine learning into your backend, I'd love to help make your project a success.
