Where systems thinking meets
hands-on AI execution.
AI systems builder and founder of Top Virtual PH — an AI-first virtual assistant agency in early-stage bootstrapping. Over the past three months I've moved from study into production: shipping ten live web applications and authoring thirty-plus reusable Claude Code skills against real marketing, legal, and small-business workflows.
The pivot is deliberate. Prior coursework in civil engineering and financial management gave me a quantitative, systems-first way of thinking; the last ninety days added the AI-native building blocks that industry is actually hiring for today — Claude Code, MCP server integration, multi-model orchestration across Claude, Gemini, and GPT, and full-stack web production on Cloudflare Pages.
My edge is in-house capability. Most of the infrastructure around me exists because I wrote it — websites, admin apps, scraping pipelines, document generators, AI routing, Google Workspace automations — and I ship fast while keeping the quality bar honest.
Building the AI-first VA agency
and everything underneath it.
Founder. Applied AI workflow developer. In-house marketing and tooling — not a contracted vendor.
- Founded an AI-first VA agency positioned around automation-enhanced services; marketing site is live and the business is actively in the client acquisition phase (pre-revenue — disclosed honestly)
- Built the agency marketing site end-to-end using Next.js on Cloudflare Pages, with a custom design system — zero external agency spend
- Designed brand identity, service catalog, and go-to-market positioning centered on AI-powered VA offerings — content automation, research agents, data operations, document generation
- Author of the agency's internal skill and automation library, including reusable templates for client onboarding, content production, and reporting
- Operating as a one-person product, marketing, and engineering team — the full in-house capability the AI-first positioning promises
- Built and deployed 30+ custom Claude Code skills and MCP server integrations against live paralegal work — case audits, status reports, email triage, calendar coordination, Drive document handling
- Shipped operational dashboards (see Shipped section) supporting US-facing legal workflows including deadline tracking and email archive search
- Engineered multi-model AI routing (Claude, Gemini, GPT) selecting the optimal model per task for cost, quality, and latency
- Built scraping and research agents for market intelligence, case research, and competitive analysis using Firecrawl, Chrome DevTools MCP, and Playwright
- Developed document generation pipelines producing US-format legal case audits, structured reports, and investor-grade DOCX outputs directly from raw data and inboxes
- This work is unpaid applied R&D for the Top Virtual PH service model — a working proving ground rather than a paid engagement, disclosed upfront for transparency

Top Virtual PH.
The agency I'm building.
