John Paul L.

I build custom software and AI-assisted workflows that reduce manual work, improve operational visibility, and give businesses more control over their processes and data. I work with small businesses, agencies, and SaaS founders that have outgrown spreadsheets, disconnected tools, repetitive administration, or fragile automations. My work includes client portals, internal dashboards, quote and estimate systems, booking and operations platforms, multi-tenant SaaS applications, API integrations, and controlled AI workflows. AI APPLICATIONS AND WORKFLOWS I build AI into real business systems where it can classify, extract, retrieve, recommend, summarize, or draft—without allowing the model to become the uncontrolled source of truth. A production AI workflow may include: • Structured AI outputs with schema validation • Human review and approval steps • Tenant-scoped retrieval and data access • Tool and API authorization • Audit trails and execution history • Retry, fallback, and failure handling • Evaluation, monitoring, and cost controls • Deterministic business rules around model decisions CUSTOM BUSINESS SYSTEMS • Client portals — customers submit requests, track progress, access records, and communicate with your team • Admin dashboards — teams manage customers, jobs, documents, reports, requests, and operational workflows in one place • Quote and estimate tools — structured lead capture, pricing logic, package recommendations, and automated notifications • Booking and operations systems — centralized records, status tracking, permissions, scheduling, and reporting • SaaS MVPs — authentication, role-based access, tenant-aware data, dashboards, integrations, and a PostgreSQL foundation designed to grow HOW I WORK Before implementation, I clarify the workflow, domain rules, users, data model, permissions, failure cases, and the decisions that must remain under human or deterministic system control. This reduces rework and prevents a common problem: building the right idea on an unreliable foundation. TECHNICAL FOUNDATION TypeScript · Node.js · React · PostgreSQL · REST APIs · Python Multi-tenant architecture · Authentication · Authorization · Transactions AI workflows · Retrieval systems · API integrations · Automation ASP.NET Core / C# when required by the project architecture GOOD FIT • You are replacing spreadsheets, manual processes, or disconnected tools • You need AI connected to a real operational workflow—not a basic chatbot • Your system requires custom rules, user roles, approvals, or structured data • You need a SaaS MVP with reliable architecture and secure tenant isolation • You need a developer who considers business logic, permissions, failure behavior, and maintainability—not only the interface Send me the workflow or business problem you are trying to solve. I will assess whether I am the right fit, identify the highest-value first phase, and explain what it would realistically take to build.
