AI Engineer &
Full-Stack Developer.
I build production AI applications, automation systems and scalable SaaS platforms.
Next.js, React, Python, Node.js, RAG, AI Agents, automation and distributed systems.
What I Build
Engineering scalable software systems across artificial intelligence, asynchronous automation, and production SaaS architectures.
AI Applications
Production LLMs & Intelligence Layers
Production LLM applications, hybrid RAG systems, autonomous task agents, and AI-powered product capabilities engineered with guardrails, streaming, and deterministic state.
AI Automation
Workflow & Business Process Pipelines
Autonomous n8n workflows, WhatsApp business bots, multi-step CRM synchronizations, webhooks, and asynchronous background queues eliminating manual friction.
Full-Stack SaaS
High-Performance Web Platforms
Production Next.js, React, Node.js and Python SaaS platforms engineered with multi-tenant architectures, modern auth, payment ledgers, and responsive interfaces.
Backend & Infrastructure
Scalable Systems & Distributed APIs
Robust REST & microservice APIs, distributed Kafka event streams, Redis caching layers, PostgreSQL/MongoDB indexing, and zero-downtime Linux deployment pipelines.
Featured Platforms & Live Systems
High-throughput SaaS platforms, distributed backend microservices, WebAR engines, and generative AI systems deployed to production.
DispatchLink
B2B Freight Marketplace Connecting Carriers & Dispatchers
A production freight marketplace designed to connect motor carriers, owner-operators, and freight dispatchers across the United States and Canada with real-time route matching and escrow settlements.
Freight dispatching is plagued by manual phone calls, untracked load confirmations, fragmented broker commissions, and slow escrow reconciliation.
Architected a unified real-time portal where carriers claim loads with automated geospatial radius search, live driver telemetry, and automated multi-tenant wallet payouts.
SchedMate
Enterprise Workforce Management & Shift Dispatching Platform
An enterprise workforce management and staff scheduling system engineered for high-concurrency healthcare and field services with automated shift reminders and audit logging.
Enterprise facilities with hundreds of nurses and field contractors faced scheduling collisions, missed shifts, and manual attendance calculation across distributed branches.
Engineered decoupled NestJS microservices backed by Kafka event streams, Redis BullMQ background workers, and strictly typed PostgreSQL schemas.
Trace3D
No-Code In-Browser WebAR & 3D Spatial Rendering Engine
An in-browser augmented reality platform enabling ecommerce brands and 3D creators to project interactive models directly into physical spaces without requiring native app downloads.
Traditional augmented reality requires users to download heavy mobile applications from the App Store, creating an 80%+ drop-off barrier for commercial brands.
Leveraged WebXR, Three.js, and WebGL to deliver photorealistic instant 3D model projection with zero app installations, triggered by simple QR codes and mobile browser links.
Kookabe AI Suite
Enterprise WhatsApp RAG Chatbot & Automated AI Voice Mail
An enterprise conversational platform integrating WhatsApp business channels with dense vector databases and synthetic voice transcription to automate 24/7 customer qualification.
Companies received hundreds of repetitive WhatsApp voice notes, PDFs, and product inquiries daily, resulting in 4-8 hour response delays and missed sales leads.
Built a hybrid RAG system with pgvector and Claude 3.7 that parses customer inquiries, searches internal PDF documentation, and generates accurate answers with human-handoff triggers.
How I Engineer Systems
Event-driven routing from edge ingestion through Redis backpressure, multi-agent evaluation, vector recall, and live SSE streaming.
LangGraph + LLM Reasoning Agent
Multi-Agent State Graph & Tool Execution
Executes dynamic routing graphs. Integrates hybrid RAG retrieval, AST syntax verification, and deterministic tool schemas.
const workflow = new StateGraph(AgentState)
.addNode("planner", planRoute)
.addNode("verifier", verifyLoadConstraints)
.addNode("synthesizer", generateDispatchAction)
.addEdge("planner", "verifier")
.addConditionalEdges("verifier", checkValid);AI Engineering
Production AI systems beyond simple chatbots.
Production RAG Systems
Enterprise retrieval-augmented generation architectures that eliminate hallucinations. Combining pgvector dense semantic embeddings with BM25 sparse keyword search, reciprocal rank fusion (RRF), and strict source attribution.
- Custom semantic chunking with metadata preservation
- Hybrid search: Dense vector embeddings + BM25 keyword matching
- Cohere / cross-encoder reranking layers for top-k precision
- Deterministic prompt templates enforcing source citations

Why Work With Me
Factual differentiators rooted in shipping production code, architectural rigor, and reliable execution.
Production Experience
Proven track record founding and shipping real software systems. Not theoretical tutorials, but revenue-generating platforms handling real users, transactions, and background jobs.
Full-Stack Ownership
End-to-end technical execution: from system architecture, database schema design, and microservices to responsive frontend interfaces and automated deployment pipelines.
AI Grounded in Engineering
I treat AI as a deterministic software layer, not magic. Every LLM workflow is protected by structured schema validation (Zod/Pydantic), error boundaries, and state graph checks.
Systems Thinking
Deep understanding of distributed architectures: message queues (Kafka/BullMQ), caching layers (Redis), database indexing (PostgreSQL/MongoDB), and zero-downtime Linux deployments.
Reliable Remote Collaboration
Experienced in remote, async development with international teams. Clear documentation, transparent communication, and rapid turnaround on Upwork and direct contracts.

AI Engineer & Full-Stack Developer
I design and build software systems at the intersection of production product engineering, distributed backend infrastructure, and generative AI.
My background spans founding commercial SaaS platforms like DispatchLink (a real-time B2B freight marketplace), delivering enterprise ERP microservices with NestJS and Kafka for SchedMate, and engineering WebAR rendering pipelines with Three.js.
In AI engineering, my focus is moving beyond simple conversational wrappers. I build deterministic multi-agent state machines with LangGraph, hybrid vector retrieval systems with pgvector, and automated workflow pipelines that eliminate operational friction.
Structured state machines, schema validation with Zod/Pydantic, and explicit fallback loops.
Redis queues, exponential retry backoff, dead-letter monitoring, and zero-downtime deployments.
End-to-end execution: database indexing, async API gateways, and low-latency frontend UIs.
