I’m building a web-based stock-trading platform and need an experienced project coordinator to jump in at the very first step. I already know the tech stack I want to use, but I have no financials or team in place yet. Your core mission is to turn a blank sheet into a clear, defensible plan and then help me pick the right developer to execute it. Here’s what I expect: • Budget calculation from the ground up, covering infrastructure, licensing, third-party market-data fees, ongoing support, and reasonable contingency. • A cost-estimation model that can be updated as scope evolves, ideally in Excel or Google Sheets with transparent assumptions. • A concise shortlist of qualified web-platform developers, ranked with pros/cons, expected timelines, and cost ranges, plus support during final selection and contract negotiation. You’re free to use the planning tools you prefer—Jira, Trello, MS Project, or similar—so long as the output is easy for me to follow. A solid grasp of brokerage APIs, compliance considerations, and cloud hosting options (AWS, Azure, or GCP) will be a big advantage. Deliverables will be accepted once the numbers make sense, assumptions are traceable, and I have a confident go/no-go decision on the leading developer. If this sounds like your wheelhouse, let’s get started.
