Most startup ideas never launch not because the idea is bad, but because development becomes slow, expensive, and overcomplicated before anything reaches users. I help startup founders, solo entrepreneurs, and non technical business owners turn ideas into launch ready AI MVPs, SaaS applications, and automation systems quickly and efficiently. My focus is simple: build functional products fast without sacrificing scalability, usability, or long-term growth. What I can help you build: ✔ AI MVPs for idea validation and product launches ✔ SaaS applications with scalable architecture ✔ AI-powered business tools and internal systems ✔ Workflow automation using n8n and API integrations ✔ Web applications and customer-facing platforms ✔ AI agents and operational automation systems I do not believe in overengineering. I focus on building the core functionality needed to launch, gather feedback, and create momentum as quickly as possible. My tech stack includes Base44, Lovable, n8n, Supabase, Firebase, React, React Native, APIs, and modern AI integrations. Clients work with me because they want: 1. Faster product launches 2. Clear communication 3. Reliable execution 4. Scalable systems 5. A developer who understands business goals, not just technical requirements Whether you are building your first MVP, launching a SaaS product, or automating business operations, I can help turn your idea into a working product ready for real users. Send me a message with your idea and I will help you map out the fastest path from concept to launch.

I’m Geri Maleck T. Broqueza, a BSBA graduate majoring in Financial Management (2010–2014) from Valenzuela, Philippines. I have a background in Accounting, Billing, and Data Encoding with hands-on experience in both Accounts Payable and Accounts Receivable processes. I specialize in Accounts Payable operations including PO & invoice matching, invoice processing, expense management, and vendor reconciliation. I have worked with accounting systems such as QuickBooks (Online/Desktop), Xero (for 3 months), and Epicor (Mallory), ensuring accurate and organized financial records. Throughout my experience with G&S Transport Corp., MFA Accounting Services, SC Homes Inc., Buildright Construction Corp. and Mallory Safety & Supply (as a freelancer here in Upwork), I have handled high-volume accounting tasks such as invoicing, reconciliation, subcontractor billing, petty cash management, and client coordination in fast-paced environments. I also have experience supporting project coordination tasks such as permit processing and operational documentation, which strengthened my attention to detail and organizational skills. I am committed, detail-oriented, and focused on delivering accurate, audit-ready accounting support. My goal is to contribute to a professional and efficient team where reliability and accuracy are valued.
