Presentation

I build custom web systems that replace spreadsheets, disconnected tools, and manual workflows — for businesses that need something built around how they actually operate.

I work with small businesses, agencies, and SaaS founders on client portals, admin dashboards, quote/estimate tools, booking systems, internal tools, and SaaS MVPs.

Relevant systems I have worked on include lead capture and estimate tools, service business reporting dashboards, booking/admin workflows, and CRM-style pipeline tools.

WHAT I BUILD
• Client portals — customers log in, submit requests, track status, and access their own records
• Admin dashboards — teams manage customers, jobs, documents, reports, requests, and internal workflows in one place
• Quote and estimate tools — structured forms that capture lead details, calculate pricing ranges, present package options, and send your team full lead context
• Booking and operations systems — centralized records, status tracking, role-based access, and operational visibility
• SaaS MVPs — authentication, role-based access, tenant-aware data, dashboards, and a real database foundation designed to grow

MY APPROACH
Before writing code, I clarify the workflow, user roles, data model, permissions, edge cases, and what the system needs to support long term. This helps avoid the common problem of building the right idea on the wrong foundation.

STACK
TypeScript · React · Node.js · PostgreSQL · REST APIs
ASP.NET Core / C# when the project architecture calls for it

WHAT I FOCUS ON
• Business rules that match how your process actually works
• Secure authentication and role-based access
• Clean database structure and proper data isolation
• Reliable workflows and maintainable code
• Systems that can grow beyond the first version

GOOD FIT
• You are replacing a spreadsheet, manual process, or disconnected tool
• Your workflow requires custom logic, user roles, or structured business data
• You need a SaaS MVP with a real technical foundation
• You are an agency or business that needs a developer who thinks about workflow, data, permissions, and business logic — not just UI

Send me a message with the workflow or business problem you are trying to solve. I will tell you honestly whether I am the right fit and what it would realistically take to build.
