I build AI systems that hold up in production. LLM agents, multi-agent pipelines, RAG architectures, and the automation around them, engineered with the safety boundaries and test coverage that keep them reliable once real users depend on them.
I am an AI engineer with an Bachlor in Generative AI from the University of Texas at Dallas and a prior background in production software and contact-center systems integration. Over the past year I shipped work across more than 30 repositories, spanning AI agents, RAG systems, and full-stack AI products, including open-source tools published to npm. My work is grounded in real engineering discipline: spec-first design, test-first implementation, and containerized deployment with CI/CD.
What sets my AI work apart is that I treat the model as one component in a system, not the whole system. The LLM proposes, deterministic code decides. That is how I build agents that can take real action without acting dangerously.
💡 What I build
⬡ AI agents and multi-agent systems with CrewAI, AutoGen, LangGraph, and LangChain that coordinate real tasks end to end
⬡ RAG pipelines with LlamaIndex, FAISS, pgvector, and sentence embeddings that ground LLMs in your own knowledge base
⬡ LLM-in-the-loop systems with hard safety boundaries, where a deterministic rule engine authorizes every action the model proposes
⬡ MCP servers that expose your tools to Claude and other agents natively over JSON-RPC
⬡ Workflow automation with n8n, Zapier, and Playwright browser automation that runs unattended with real error handling and retries
⬡ Production APIs in FastAPI, Django, and Flask, and full-stack apps in React 19 and Next.js
⬡ Provider-agnostic LLM integration across OpenAI, Anthropic, Google, Groq, Mistral, and local Ollama models behind one interface
🛠️ Selected work
orch, an open-source CLI published to npm that routes prompts across multiple AI coding agents through a single interface, with budget-aware selection learned from real quota and rate-limit failures
A human-in-the-loop review service for AI-authored documents: a containerized HTTP API plus an MCP server exposing 20 review tools, deployed multi-user behind OAuth
An LLM trading research bot on the Binance test network, where the model reasons over market data through read-only tools and a deterministic risk engine is the only path to an order, verified live and backed by roughly 470 tests
A full job-application platform: a FastAPI agent service that scouts, scores, and tailors applications across six sources, with a provider-agnostic LLM layer and Playwright auto-apply, fronted by a Next.js dashboard
An autonomous server-maintenance agent packaged in Docker, and a Chrome extension that fills web forms from your own documents using a pluggable local-or-cloud AI layer
🧠 Background and research
Generative AI, University Texas at Dallas. My dissertation studies whether large language models actually know what they do not know, probing model calibration and hallucination at knowledge boundaries. I also write about LLM reliability on my engineering blog. Before that I spent years in production software and contact-center systems integration with tools like Cisco Finesse, ActiveMQ, and Jira automation, so I am comfortable both building greenfield AI products and working inside existing enterprise systems.
🛠️ Core stack
Languages: Python, TypeScript, Go, JavaScript
AI: LangChain, LangGraph, CrewAI, AutoGen, LlamaIndex, MCP, OpenAI API, Anthropic API, Gemini, Groq, Ollama, RAG, PyTorch, Hugging Face
Backend: FastAPI, Django, Flask, NestJS, Node.js
Frontend: React 19, Next.js, TypeScript, Tailwind
Data: PostgreSQL, SQLite, FAISS, pgvector, Redis, Firebase
Infrastructure: Docker, Docker Compose, GitHub Actions, CI/CD, Nginx, VPS deployment
If you need an LLM agent, a multi-agent system, a RAG pipeline, or a full-stack AI product built by someone who cares whether it still works next month, send me a message and tell me what you are building. I will tell you honestly whether I am the right fit.

I build production grade SaaS platforms, AI systems, realtime applications, high concurrency backend infrastructure, and full stack mobile and web platforms.
Most developers today can generate code with AI tools. Very few can architect systems that remain scalable, maintainable, and reliable once real users, payments, concurrency, and operational complexity enter the picture.
That’s where I work best.
My background is deeply rooted in backend engineering, distributed systems, and full stack architecture. AI has simply become another layer in the systems I design, not a replacement for engineering fundamentals. I work with startups and growing businesses that need more than just MVP development. They need stable foundations that can scale properly over time.
I specialize in building:
* Multi tenant SaaS platforms
* AI orchestration and agentic workflows
* Operational AI systems integrated into real business workflows
* High concurrency backend infrastructure
* Payment and subscription systems
* Realtime dashboards and event driven systems
* Queue based architectures and worker orchestration
* Telephony and communication platforms
* Customer engagement and loyalty systems
* Workflow automation platforms
* RBAC and enterprise permission systems
* QR based tracking and attendance systems
* API platforms and microservices architecture
My AI experience goes beyond simple chatbot integrations and includes:
* RAG pipelines and retrieval systems
* Agentic workflows and AI orchestration
* Tool execution pipelines
* AI voice calling systems
* Operational AI agents
* Document intelligence and OCR pipelines
* Permission aware retrieval systems
* AI powered workflow automation
* AI integrated backend infrastructure
My primary stack includes:
* Node.js, TypeScript, Python, PHP
* React, Next.js, Angular
* React Native, Expo, Flutter
* FastAPI, Tornado, Django, Flask, Express, NestJS, Laravel, Symfony
* PostgreSQL, MySQL, Redis, Supabase, MongoDB, DynamoDB
* Docker, Kubernetes, AWS, GCP
* OpenAI, Claude, LangChain, pgvector
* Websockets, SSE, realtime systems
* CI/CD pipelines and cloud native deployments
* Large scale data extraction using Selenium, PlayWright, Requests, HTTPx, Requests
* AI Chatbots, Slack bot, Telegram bot, Discord bot
* Cursor, Antigravity, Github Co-Pilot, Codex, Amazon Q, Google AI Studio
* Lovable, Bolt.New, V0.Dev, Base44 Apps
I regularly work with:
* Queue systems and distributed workers
* Event driven architectures
* Payment infrastructure including Stripe
* Backend optimization and scaling
* Transactional consistency and idempotency
* Observability, monitoring, and debugging
* Realtime synchronization systems
* Serverless and microservices environments
Most of my engineering foundation was built long before the current AI wave, with a strong focus on backend systems, scalability, distributed infrastructure, and software architecture.
I care heavily about:
* Clean architecture
* Performance under load
* Execution reliability
* Long term maintainability
* Scalability and operational stability
* Backend observability and debugging
* Cost efficient infrastructure design
* Transactional integrity and failure handling
I don’t just build features. I help architect systems correctly so they survive real growth.
If you’re building a serious product and need an engineer who can own complex technical problems independently, I’d be happy to discuss your project.
