Claude Code & Claude Cowork Architect — production AI agents, custom skills, and agentic systems for serious operators.
I build production-grade AI systems on Claude Code and Claude Cowork — multi-agent applications, custom Claude skills, and MCP-integrated workflows that operate on live data, not demos. Becoming a member of the Anthropic Claude Partner Network. 790+ completed Upwork projects, 3,200+ hours, 4.9 across 485 reviews. Ex-Barclays Bloomberg AVP.
Most "AI freelancers" wire up a chatbot. I architect agentic systems the way an engineering team would: structured project context, specialized subagents, reusable skills, error handling, and live system integration over the Model Context Protocol (MCP) — the kind of systems that survive audits, scale past 10x volume, and keep working when your team turns over.
WHAT I BUILD WITH CLAUDE
→ Claude Code applications — full products architected and shipped end-to-end (React / FastAPI / Supabase), with custom subagents and skills doing the engineering. Recent: a Singapore recruitment portal with government-grade auth and live ATS, calendaring, and payment integrations.
→ Multi-agent systems — orchestrated agents that decompose complex work and hand off to each other. Recent: a public-sector bidding engine (Watchdog → Evaluator → Builder) using RAG to assemble 80% proposal drafts.
→ Custom Claude Skills — reusable, domain-specific capabilities (in the project's .claude skills folder) for document parsing, matching, compliance checks, and internal operations.
→ MCP integrations — Claude connected to live systems: Supabase, Airtable, Google Drive, Monday, n8n. Real read/write, not screenshots.
→ Claude Cowork operating systems — AI knowledge-workers that replace fragmented internal tooling for ops teams.ALSO FLUENT IN: n8n, OpenAI / Codex, VAPI & Retell (voice AI), RAG pipelines, HubSpot / GoHighLevel / Pipedrive, and Make Platinum Partner — used where they're the right tool alongside Claude.
WHO I WORK WITH
Founders and operators at $1M–$50M ARR companies in healthcare, fintech, and real estate who need automation that behaves like infrastructure, not duct tape:
→ Healthcare — intake, scheduling, HIPAA-aware agentic workflows
→ FinTech — KYC, compliance reporting, document processing
→ Real Estate — lead qualification, listing automation, broker dashboards
WHY CLIENTS HIRE ME OVER A $25/HR FREELANCER
I came to AI through 8 years at Barclays Investment Bank and Bloomberg, where a broken process cost millions. I architect systems with monitoring, documentation, and reliability built in — not bolted on after the first failure. I run Growwstacks, a 10-person agency in the Anthropic Claude Partner Network. You hire me, you get the agency: PM, QA, and the bandwidth for enterprise-grade scope.
HOW I WORK
* Discovery call (free, 30 min) — your workflow, bottlenecks, stack
* Architecture proposal — written scope, not a verbal estimate
* Build with weekly demos — staging from day one
* Launch with documentation and video walkthrough
* Ongoing support — most clients stay on retainer
CREDENTIALS
* Anthropic Claude Partner Network
* Make Platinum Partner & Community Leader
* 15 years software engineering & process architecture
* Ex-Barclays Bloomberg AVP
Let's talk if you have a real AI problem and a real budget. I'm not the cheapest — I'm the one you hire when the cheap one didn't work.

Years of systems engineering inside an MSP as well as consulting enterprise clients put me in 600+ business environments: Microsoft 365, Google Workspace, on-prem Exchange, hybrid identity, endpoints, and all the ways those choices age. That breadth is what clients actually hire: the decision made right the first time, then built by the same person who made it.
It works because the recommendation stays neutral. I have told clients to keep Google Workspace when they came to me asking about Microsoft 365. The advice is the product, and it is worthless the moment it bends toward a license sale.
The record: Top Rated, 100% Job Success across 42 jobs, rated 5.0 on every reviewed engagement. Migrations delivered for universities, counties, and public school systems. Certified MS-102 Expert, SC-300, SC-200, AZ-104, MD-102.
Engagements take three shapes:
The decision. Platform, architecture, licensing, security posture. A written recommendation with real costs and named risks, built from your environment instead of a template.
The build or the move. Migrations and deployments across Microsoft 365, Google Workspace, Exchange, identity, and endpoints. Fixed price, cutover in your quiet hours, rollback in writing. Tenant consolidations, GoDaddy exits, Exchange upgrades: boring, planned, done.
The rescue. A breached tenant, a stalled migration, an environment nobody documented. I investigate, recover, harden, and document so it never repeats.
Every engagement runs on a variation of my six-phase method: Align, Diagnose, Architect, Plan, Transform, Operationalize. Fixed scope, fixed price, named deliverables, knowledge transfer. You know what you bought before you pay and what shipped after. I do hourly engagements too as long as we both are aligned and expectations are communicated upfront.
Fixed-fee assessments run $1,500 to $5,950 and end in a scored report with remediation already priced. Also a plus, if you chose to remediate I will discount the fixed assessment price, An anonymized sample is public on my site. Book a consultation and leave with a written plan, or message me what is on fire. If I am not the right fit for the job, you will know from my first reply.
