The Builder's Portfolio: Why I Ship Products Outside My Day Job

The Portfolio

I'm a Senior Vice President at Citi. I also build products. Not as a hobby — as a discipline.

  • SimpliInvest — AI-powered investment risk scoring
  • SimpliRentIt — AI-powered rental property management
  • MoeCloud — managed IT services for SMBs
  • Joshua — an AI assistant that manages my business communications
  • Blockchain AI Foundation — education and research at the AI-blockchain intersection

Each product solves a real problem. Each one teaches me something I bring back to my corporate role. And together, they form a body of work that no title or resume bullet can replicate.

Why Build?

Credibility Through Shipping

When I advise a team at Citi on AI architecture, I'm not drawing from theory. I'm drawing from building SimpliInvest's multi-agent risk scoring pipeline last month. When I evaluate a vendor's platform claims, I can compare them against what I've built and deployed myself.

Shipping products gives you a calibration that nothing else provides. You know what's hard, what's easy, what vendors are exaggerating, and what's genuinely impressive — because you've done it yourself.

Full-Stack Understanding

In a corporate role, you specialize. You manage infrastructure, or you manage teams, or you manage strategy. Building products forces full-stack thinking:

  • Design — what does the user actually need?
  • Architecture — what's the right technical approach?
  • Engineering — write the code, debug the issues, ship the feature
  • Operations — deploy, monitor, maintain, iterate
  • Business — pricing, marketing, user acquisition, retention

This breadth makes you a better leader because you understand every function your team performs.

Speed as a Superpower

Corporate environments move at corporate speed. Building solo or with a small team teaches you what's actually possible when you remove the overhead. A feature that takes a corporate team two sprints takes an evening when you own the entire stack.

That calibration is valuable. It helps you distinguish between genuinely complex work and unnecessary process.

The Products

SimpliInvest

Problem: Retail investors lack institutional-grade risk analysis. Solution: AI agents that analyze any ticker and produce instant risk scores with explanations. What it taught me: Multi-agent AI orchestration, structured outputs with Zod, building resilient data pipelines over flaky APIs.

SimpliRentIt

Problem: Small landlords run operations manually. Solution: AI-powered screening, lease management, and maintenance workflows. What it taught me: Domain expertise matters as much as technical skill. Also, how to translate enterprise patterns into consumer UX.

MoeCloud

Problem: SMBs need enterprise-grade IT without enterprise complexity. Solution: Managed M365, Egnyte, security, and media production as a bundled service. What it taught me: Service delivery, client management, recurring revenue models, and the power of bundling technology with content.

Joshua

Problem: I needed an AI assistant that could manage business communications across WhatsApp — handling client intake, case management, and task tracking. Solution: A custom AI copilot with voice support, natural language parsing, and WhatsApp integration. What it taught me: Conversational AI design, voice UX, building reliable systems on messaging platforms.

Blockchain AI Foundation

Problem: AI and blockchain are converging with no coordinated effort to ensure responsible development. Solution: Education, research, and community building at the intersection. What it taught me: Community building, thought leadership at scale, bridging technical and non-technical audiences.

The Compound Effect

These products don't exist in isolation. They compound:

  • SimpliInvest and SimpliRentIt share the same tech stack, so improvements to one benefit the other
  • Joshua manages communications for MoeCloud clients
  • The Blockchain AI Foundation provides a platform for thought leadership that drives consulting and speaking opportunities
  • Every product generates insights that make my corporate work sharper

This is the builder's portfolio effect: each thing you build makes everything else better.

The Practical Advice

If you're a technology leader considering building on the side:

  1. Solve your own problems first. The best products come from personal pain points.
  2. Use a consistent tech stack. I use Next.js + Firebase + TypeScript for everything. Consistency is a force multiplier.
  3. Ship small, ship often. A working MVP beats a perfect plan.
  4. Let your builds inform your leadership. The lessons flow both ways.
  5. Don't ask permission. Build on your own time, with your own resources, on your own infrastructure. Keep it clean.

The Legacy

Titles change. Companies reorganize. But a portfolio of shipped products is permanent proof that you can envision, build, and deliver. It's the strongest signal in technology: this person ships.
