Full-Stack Developer for SaaS Startups

Define the first release. Build the workflow that matters.

Turn your SaaS idea into a focused first release. Work directly with me on the core workflow, user accounts, billing, and the parts your customers need to try the product.

The Problem

An unclear scope makes every estimate hard to trust. Before building, you need to decide which customer problem the first release will solve, what can wait, and how you will test it with users.

The Build

My portfolio includes BookBed, a booking product built with Flutter and Firebase, Callidus, a clinic platform built with React and Firebase, and the Pizzeria Bestek ordering website. Their case studies explain the workflows and implementation choices.

  • Direct collaboration on scope, implementation, and handover
  • Bidirectional iCal sync with booking-conflict detection
  • Tenant isolation using Firebase security rules
  • Real-time order updates with Supabase

In detail

Define what the first release must prove

Name the user, the problem, and the workflow that should change. Then decide what evidence would justify further investment: a completed task, a successful booking, or a payment, for example. Keep operational requirements such as account access, failure handling, and data isolation in scope; they are part of a usable release.

Review relevant implementation evidence

Ask a developer to explain their contribution, architecture choices, and what happened when the workflow failed. Review the code or case study where available. A screenshot does not establish reliability, and a working demo does not prove every production requirement.

BookBed covers booking and calendar workflows; Callidus covers a clinic platform. Use those examples to discuss your requirements, not to assume identical delivery dates.

Agree on milestones and decisions

Define acceptance criteria for each milestone, who provides feedback, and how changes are approved. Ask for regular demonstrations of completed work, with frequency agreed for the project. Keep the repository, setup instructions, and deployment responsibilities clear throughout the engagement.

Treat budget and timeline as scope-dependent

A useful estimate identifies integrations, roles, data migration, testing, and release dependencies. Compare proposals with the same scope and support requirements; the number of people on a team does not determine which proposal is faster or cheaper.

Fixed-scope work fits a sufficiently defined deliverable. Hourly or time-boxed work can suit investigation and changing requirements when spending limits and review points are explicit. Neither billing model guarantees the outcome.
