How I Hired Freelancers Who Went Way Over The Deadline

You know how the software developers are always mocked because they don’t comply with the time limits? Read this article about my experience of hiring a team of freelancers who went way over the deadline.

Not so long ago I hired a team of freelancers to work on a project of mine.

Everything started as it usually starts. I found several teams, some through friends and some – through a website. I met with team leaders, we discussed my requirements, we agreed on time and on a budget. I picked the team that looked the most reliable to me, they rolled up their sleeves and started to work.

What interests you when you read an article or a book about an architecture of some big system, or about new frameworks, or design patterns, or some new fancy tools?

To me, the most interesting thing is why they did it like they describe.

Geo Information System: Requirements

Bad-ass development of scalable systems with lots of user requirements, tight schedules and limited resources? Ask me how!

This is the first article in series about building a Geo Information System. Here I’m going to tell you about user requirements we gathered before we rushed into development.

I’m starting a series of articles about building a geographic information system, or GIS-system. With a great team of smart and very dedicated developers, we created a robust scalable solution that our users were happy with. Or, almost happy. You can never make users completely happy. Sigh.
