I know many businesses rely on people instead of systems, and that's exactly what slows their growth.
I can help businesses build AI-powered applications and smart automation systems that save time, reduce manual work, and scale with confidence.
As your business grows, so does the number of tools, processes, and repetitive tasks. Before long, your team is switching between apps, updating records manually, chasing follow-ups, and using multiple platforms just to complete one workflow.
Whether you need a custom AI application, an internal business tool, AI agents, workflow automation, API integrations, or a complete business system, I build solutions that work together seamlessly—so your business runs smarter, not harder.

STOP WASTING MONEY ON AI THAT DOESN’T DELIVER
I deliver production-ready AI agents that integrate, scale, and produce measurable business impact.
Before writing a line of code, I map workflows, identify bottlenecks, and design AI systems that don’t just run, they deliver real business value.
◼️WHAT I BUILD
⚫ AGENTIC & GENERATIVE AI
▪️Autonomous AI agents and multi-agent systems (tool-calling, memory, planning)
▪️Custom RAG pipelines with hybrid search (semantic + keyword)
▪️LLM integrations: OpenAI, Anthropic Claude, Google Gemini
▪️AI model fine-tuning, expert prompt engineering, structured outputs
▪️Voice AI: real-time speech-to-speech agents (ElevenLabs, Whisper, Deepgram)
▪️Multi-modal apps: vision, document intelligence, image generation
▪️MCP (Model Context Protocol) server development and integration
⚫ AI INFRASTRUCTURE & VECTOR SEARCH
▪️Vector databases: Pinecone, Weaviate, pgvector, Chroma, Qdrant
▪️Embedding pipelines, chunking strategies, document ingestion at scale
▪️LLM observability and evaluation frameworks: LangSmith, Helicone, Arize
▪️AI workflow orchestration: n8n, Make, Zapier, and custom pipelines
⚫ PRODUCTION-FIRST AGENTIC AI
I design AI agents that run reliably in real operations:
▪️Tool-using agents with strict action boundaries (no hallucinations)
▪️Structured outputs with schema validation and deterministic rules
▪️Built-in failure handling: retries, fallbacks, human handoff, safe uncertainty
⚫ MULTI-AGENT ORCHESTRATION (LANGGRAPH + TOOL ROUTING)
I build multi-agent systems for complex workflows:
▪️Stateful orchestration: supervisor agent + specialist worker agents
▪️Safe tool routing with permissions, validation, and deterministic controls
▪️Long-running workflows with checkpoints, retries, and observability
▪️Typical applications: support triage, scheduling, sales qualification, onboarding, document intake
⚫CLOUD DEPLOYMENT & RELIABILITY (AWS + PRODUCTION)
I deliver AI systems that survive real-world production:
▪️Serverless or container-based deployment with clean CI/CD pipelines
▪️Queues, async workers, scheduled jobs, retries, rate limits, dead-letter handling
▪️Secure API gateways, authentication patterns, secret management, audit logs
▪️Full monitoring and observability: logs, metrics, traces, alerts, runbooks
⚫LEGACY SYSTEMS INTEGRATION
I integrate AI into real-world environments:
▪️Middleware, webhooks, adapters, and integration layers
▪️Idempotent writes and data validation to protect existing systems
▪️Safe, explainable actions your operations team can trust
⚫ HOW I WORK?
▪️Define workflows, success metrics, and potential failure modes
▪️Design agent architecture: single vs multi-agent, tools, permissions, and state management
▪️Implement voice agents, tool routing, and system integrations
▪️Harden for production: testing, guardrails, retries, and observability
▪️Deploy to the cloud and safely iterate with real traffic
Your AI project should drive real impact from day one.
Let’s define your workflows, scope your MVP, and deploy agents that actually work in production. Ready to get started?

I used to be the person on the support team fielding the same integration question five times a day - because the docs never explained it properly. That's what pulled me into technical documentation engineering.
Not theory. The actual gap between what a product does and what a developer or non-technical end-user can figure out from the docs alone.
Since then, I have spent my time cleaning up that gap for SaaS companies. I write and structure API documentation that developers can actually follow without pinging support - OpenAPI/Swagger specs, endpoint references, authentication guides, quickstarts, and the kind of "Getting Started" pages that stop a new user from bouncing in the first five minutes.
A good chunk of my recent work has also been in n8n - documenting custom nodes, workflow logic, and automation setups so that teams (and their clients) understand exactly what's running under the hood and why. I like this kind of work because it sits right at the intersection of technical accuracy and plain-English clarity - you need both, or the doc is useless.
{What I bring to your project}:
- API documentation (OpenAPI/Swagger, REST, Postman collections)
- SaaS product docs, help centers, and onboarding guides
- n8n workflow and node documentation
- Rewriting/auditing existing docs that are outdated, inconsistent, or just confusing
If your product works but your documentation is quietly costing you support tickets, churn, or dev time - that's exactly the kind of mess I like sorting out.
Send me a message and tell me what you're working with.
-------------------------------------------------------------------
{My Background and Skillset}
With a strong background in software engineering and web development, I understand the systems behind the documentation. This allows me to work directly with APIs, codebases, product teams and technical stakeholders to create accurate, well-structured documentation that stays useful as products evolve.
🔹 User Guides | How-to Guides
I create clear, task-focused documentation that helps users understand your product, complete workflows efficiently, and reduce dependency on support teams.
✅ User guides
✅ How-to guides
✅ Step-by-step tutorials
✅ Product onboarding guides
✅ Feature walkthroughs
✅ Knowledge base articles
✅ FAQs and troubleshooting guides
✅ Internal process documentation
✅ User manuals
✅ Visual workflows and screenshots
🔹 API Documentation (OpenAPI / Swagger Expert)
I create complete, production-ready API documentation that includes:
✅ Clear endpoint descriptions
✅ Request body parameters
✅ Query parameters & path parameters
✅ Authentication flows (JWT, OAuth, API Keys)
✅ Response structures with status codes
✅ Error codes with detailed schemas
✅ Properly defined data models
✅ Example requests & responses
✅ Postman collections
✅ SDK usage examples
I work extensively with:
Markdown • YAML • JSON • OpenAPI • Swagger • Redocly • Postman • GitHub ▪︎ ReadMe • Google Docs ▪︎ Zendesk • Docusaurus
Your APIs will not only function well - they will be understood instantly.
🔹 Developer & Technical Documentation
I create:
✅ Developer Guides
✅ API References
✅ SDK Documentation
✅ Integration Guides
✅ Database Documentation (SQL & NoSQL)
✅ System Architecture Documentation
✅ Technical Blogs & Articles
✅ Internal Engineering Documentation
✅ System Operating Procedures (SOPs)
✅ User Manuals
✅ How-To Guides
✅ Step-by-Step Tutorials
Whether your audience is developers, internal teams or non-technical users - I adapt tone, depth and structure accordingly.
🔹 Developer Portals & Documentation Platforms
I build structured, branded documentation portals using:
✅ Redocly
✅ ReadMe
✅ GitBook
✅ Docusaurus
✅ Mintlify
✅ Stoplight
✅ Confluence
✅ GitHub
I ensure your documentation is searchable, scalable, version-controlled, and beautifully structured.
🔹 Technical & Engineering Strength
My technical capabilities allow me to go beyond surface-level writing:
✅ Testing and validating APIs with Postman
✅ Running and testing SDKs
✅ Code commenting and codebase documentation
✅ JavaScript & TypeScript documentation
✅ Python code refactoring & documentation
✅ REST API workflows
✅ JSON, YAML, HTML, CSS
✅ Database structure documentation (SQL | NoSQL)
Because I understand the code, I document it accurately.

HIPAA-aware AI voice agents for healthcare — built on Synthflow, Retell AI and ElevenLabs. I turn missed calls into booked appointments with 24/7 reception, appointment booking and CRM automation that capture every inquiry and route it into your real systems.
I specialize in production voice agents (Synthflow, Retell AI, Voiceflow, ElevenLabs) wired into your real systems — GoHighLevel, HubSpot, EHR / booking tools, Twilio telephony, plus AI chat & WhatsApp assistants (ManyChat, WATI) — with OpenAI / GPT-4o driving the conversation and n8n / Make orchestrating the workflow end to end.
Healthcare is where I'm strongest. Recent work includes:
Patient growth & booking across a 55-clinic chiropractic network (Australia)
24/7 AI shift-coordination for UK NHS healthcare staffing
Bilingual (EN / ES) after-hours patient reception (Miami)
Inbound AI receptionists for dental & medical clinics
AI voice agent for medical consults (Synthflow + PracticeQ / EHR)
I design with compliance in mind: HIPAA-aware architecture, PHI minimization, audit logging, and clear medical-escalation rules — the AI never diagnoses or gives medical advice; it routes to your staff.
Beyond healthcare, I deliver the same voice + integration stack for clinics, agencies, startups, and appointment-driven service businesses.
What I deliver:
AI voice & chat agents: inbound / outbound calls (Twilio, VoIP), WhatsApp & web chat, FAQ, triage, appointment booking
Lead qualification, enrichment & conversion bots
Knowledge-base & RAG assistants (document / data retrieval, multi-agent)
AI automation for business operations (n8n, Make, Zapier) + API / webhook integration
CRM & calendar integration (GoHighLevel, HubSpot, Google Calendar)
QA & testing for conversation flows and backend logic
Backed by 8+ years in project management and backend development (JavaScript, Node.js, Express, serverless, Supabase), I own the full delivery cycle — architecture, conversation design, QA, deployment.
Let's build a voice agent that fits your business.
