I build AI products end-to-end — from agent design and RAG pipelines to production deployment. 18+ years of full-stack engineering is what lets me take LLMs from notebook to real users, at scale.
AI Product Architecture
How I design and ship AI products end-to-end — from LLM orchestration to production delivery.

LangChain, LangGraph, OpenAI, Claude, RAG, pgvector
Agents, RAG pipelines, evals, guardrails
Backend
NestJS, Laravel, Node.js, Python
APIs, auth, queues, business logic
Frontend
Next.js, Angular, React, streaming UIs
Chat UIs, dashboards, design systems
Cache & Queues
Redis, Supervisor, Horizon
Session, cache, jobs, real-time events
Mobile Apps
Flutter, Dart, React Native
Cross-platform, store pipelines, OTA
CDN & Delivery
Cloudflare, S3, DO Spaces
Assets, WAF, edge caching, storage
Infrastructure

IaC, CI/CD, zero-downtime deploys
What defines me
AI product delivery from agent design and RAG pipelines to production at scale.
LLM orchestration with LangChain and LangGraph — evals, guardrails, and observability built in.
RAG and knowledge systems that stay accurate, auditable, and cost-aware in production.
Full-stack backbone — ship the model, UI, API, and infra as one product.
Hands-on engineering that keeps code ownership and quality high.

AI Engineering Guideline & Mindset
From agent design to production, I build AI products with clear architecture, rigorous evals, and full-stack delivery.
LLM & Agent Engineering
From prompt to production
LangChain and LangGraph orchestrations that reason, use tools, and stay reliable under real traffic.
- Multi-step agents, tool use, memory
- Evals, guardrails, and cost control
RAG & Knowledge Systems
Accurate, auditable answers
Retrieval-augmented generation with vector search, hybrid retrieval, and tight grounding on your data.
- pgvector, Pinecone, LlamaIndex
- Chunking, reranking, citation quality
Chatbots & Assistants
Conversational AI that ships
Production chat surfaces across WhatsApp, Telegram, and the web — with intent, context, and graceful fallbacks.
- Streaming UIs with Next.js
- Multi-tenant deployment & telemetry
AI-Ready Backends
APIs built for LLM traffic
NestJS and Laravel services tuned for streaming, long-running jobs, vector stores, and third-party LLM SLAs.
- Queues, retries, idempotency
- Observability and error tracking
Product UX for AI
Next.js frontends
Chat UIs, dashboards, and admin surfaces that make model behavior legible to users and operators.
- Streaming, tool calls, and state
- Design systems and component reuse
Ship to Production
Full-stack delivery
From Terraform to App Store — the backbone that turns AI features into shipped products.
- CI/CD, zero-downtime, observability
- Mobile (Flutter) when the product needs it
