Project details
You will get a dedicated MERN stack developer who works exclusively on your SaaS or web application during the selected engagement period.
This service covers frontend development using React or Next.js, backend API development with Node.js and Express, and scalable data handling with MongoDB or Supabase. Work is carried out across feature development, integrations, bug fixes, performance optimization, and ongoing product improvements.
What makes this different is the approach. Instead of quick fixes or fragmented contributions, the focus is on consistent execution, clean architecture, and long-term maintainability. Tasks are implemented with a clear understanding of your product goals so the codebase remains stable as it grows.
You can expect clear task ownership, predictable progress, and development aligned with your existing workflows and sprint plans. This setup is ideal for teams that need reliable development capacity without the overhead of hiring a full-time in-house developer.
š Choose a weekly, part-time, or full-time option based on your needs and roadmap.

Unfortunately, my experience with this team was very disappointing. They seemed to lack the technical expertise and experience required for a project of this complexity. Despite spending a considerable amount of time and money, I did not receive any meaningful results.
Communication was polite, but progress was extremely slow, and there was little evidence that they fully understood the technical challenges involved. In the end, I felt that the project never moved beyond the early stages.
I would recommend this team only for very simple tasks. If you have a complex or technically demanding project, I suggest looking for developers with more proven experience to avoid wasting your time and budget.
