You will get a SaaS MVP architecture sprint: schema, tech stack, and build estimate
Project details
Most failed builds are failed architectures. This sprint resolves the system before anyone commits budget to code.
You get an architecture Blueprint: an architecture recommendation with the alternatives and trade-offs written down, a relational database schema, a technology-stack recommendation with reasoning, a user permission structure, a file-storage and integration strategy, a feature-priority roadmap, and a development estimate for V1 - delivered in a review session where you can challenge every assumption.
I have built and shipped this kind of system myself. HerpSync is a live multi-tenant SaaS serving public tenant pages on both platform subdomains and customer-owned custom domains. MapProx is a live field-sales mapping and route-optimization platform with web and native mobile apps sharing one backend. I make architecture decisions I have had to live with in production.
Design-first background: web work since 2004, EVC Studios since 2007 - so the system I plan is one people can actually use.
You own everything produced. If we build together afterward, the Blueprint becomes the plan and this fee applies toward the project. If not, it is still yours and it will hold up.

About David
Custom Software & AI Solutions Developer
Selma, United States - 5:44 pm local time
Two systems I designed and built end to end are live:
• HerpSync — a multi-tenant SaaS for reptile breeders, serving public tenant pages on both platform subdomains and customer-owned custom domains (soft launch).
• MapProx — a field-sales mapping, route-optimization, and visit-tracking platform, with a React web app and a native iOS/Android app sharing one backend (publicly available).
Typical engagements:
- Focused SaaS MVPs
- Multi-tenant platforms with organization-level isolation and role-based access
- Internal workflow dashboards and customer portals
- CRM, payment, and third-party API integration layers
Stack: Next.js, React, TypeScript, Node.js REST APIs, PostgreSQL (Prisma/Drizzle), Stripe, RBAC, webhook and queue-based integrations, Claude and OpenAI API integration, and React Native/Expo mobile delivery.
My background is design first — a graphic design degree and web work since 2004 — so what I build is usable, not just correct. I've run EVC Studios since 2007.
AI-accelerated engineering speeds the repeatable work: research, implementation, testing, analysis, and documentation. It's an execution multiplier, not the product. Every requirement, architecture decision, data boundary, security-sensitive choice, and production release passes through my review and stays my accountability.
How I work: most projects start with a paid discovery and architecture review — data model, tech stack, permission structure, integration surface, and a build estimate — so we scope from evidence instead of assumptions. If the architecture is right, the build is predictable.
Good fit if you can describe the one core workflow your system must support first. Not a fit for template sites or page-builder work.
Steps for completing your project
After purchasing the project, send requirements so David can start the project.
Delivery time starts when David receives requirements from you.
David works on your project following the steps below.
Revisions may occur after the delivery date.
Kickoff call and requirements review
A working session to confirm scope, users, constraints, and what a successful V1 must let people do.
Architecture and data model design
I design the relational data model and the system architecture, and document the alternatives considered and the trade-offs accepted.
