Project details
Most founders fail not because they can't build — but because they build the wrong thing. In one 2-hour session, we stress-test your idea: ICP, value proposition, PMF signals, and monetization logic. You get a Go/No-go recommendation with clear reasoning. If Go - your $500 is credited toward the MVP build

Need Full Stack Developer, SaaS Developer or MVP Developer for Startup SaaS

Senior Full Stack Developer, SaaS Developer — HR Payroll Platform
Volodymyr joined at a stage where we needed more than execution — we needed someone to help us think.
He’s a strong SaaS developer and Python full stack developer who can hold both the technical and product perspective at the same time. As a React developer, he also bridged the gap between backend logic and what the frontend team actually needed to move forward.
For startup MVP work, the challenge isn’t always building fast — it’s knowing what to build first. Volodymyr helped us define the MVP development scope, structure the REST API cleanly, and set up the right API integration and AI integration hooks so the team could keep moving without rearchitecting later.
Any web developer or software developer who joined after him had a clear foundation to build on. That’s rare, and it’s the kind of thing you only get from someone who’s done real AI SaaS development at scale.
Would recommend him to any early-stage team that needs architecture thinking, not just sprint delivery.

Full-stack developer for B2B SaaS (experiences with Large Systems)
Working with Volodymyr on our B2B SaaS product was exactly what we needed at a critical stage. We weren’t looking for someone to just ship an MVP fast. We needed a SaaS developer who understood how real SaaS products are structured and why early architectural decisions matter a lot down the road.
The SaaS development process was well-structured from day one. Volodymyr asked the right questions, flagged potential issues for MVP before they became problems, and helped us build foundation we’re actually confident scaling. Beyond just executing the task, he proactively recommended next steps, including AI features and third-party integrations that would add real value as the product grows.
Great experience working with a developer who thinks beyond the current sprint. Would absolutely work together again on future SaaS projects.

PropTech MVP Development - Real Estate Platform / Tenant Portal
Great experience working with Volodymyr. We had a very productive consultation phase that helped lay a solid foundation for our B2B platform. He demonstrated strong experience in SaaS development and approached the project with a clear understanding of MVP strategy and delivery.
As a skilled full stack developer, Volodymyr showcased deep technical expertise in Django and React, along with strong experience in building complex end-to-end platforms, which was exactly what we needed. Because of this, he asked the right questions, quickly aligned on the technical approach, and provided thoughtful recommendations throughout the process.
He also delivered clear, well-structured materials that made planning the next development steps straightforward. I’d be happy to continue into the next phase with him and would gladly work together again in the future.
