Tempesta Technologies

Introduce your business and what you do there.

We’re the steward foundation of a community-developed fork of a MySQL database software. We get code contributions from member companies and other contributors.

What challenge were you trying to address with Tempesta Technologies?

The challenge was a lack of capacity. We needed to find people that knew the database, and we knew from earlier situations that Tempesta fit that requirement.

What was the scope of their involvement?

We have open-source code, so it’s free for everyone to see and we work through a GitHub interface. Tempesta is working on several features of the database.

What is the team composition?

We’re working primarily with Alexander (CEO), who’s in charge of coordination. I believe there are 2-3 other individuals helping out.

How did you come to work with Tempesta Technologies?

They’d worked with our corporate entity earlier on, and they did a good job.

How much have you invested with them?

The cost so far is around €20,000 (approximately $24,200 USD).

What is the status of this engagement?

We started working with Tempesta in February or March 2020, and it’s ongoing. We assign them work based on our budget and review capacity. We’re not working at peak capacity right now.

What evidence can you share that demonstrates the impact of the engagement?

Users can ask for new features and vote on which are the most important through our Jira. We have a huge backlog of requests, and we’ve been able to close more of them with Tempesta’s help.

Picking requests is not a trivial thing because they need to be closable with a limited amount of experience on the code base, and be beneficial to a large portion of the user base. It’s a bit too early to say how Tempesta’s work has panned out, but we’ve released a number of features with their help.

How did Tempesta Technologies perform from a project management standpoint?

We use Jira and GitHub for specifications, pull requests, and tracking what’s been done. We review their code internally and communicate through Zoom, WhatsApp, and email.

What did you find most impressive about them?

The most important part is Tempesta’s ability to deliver what we really need. It’s not easy for anyone to contribute to a huge existing codebase. We have hundreds of thousands of lines of code, parts of which are over 10 years old, coming from multiple contributors.

From a process standpoint, communication from Alexander is very good. He answers promptly and is available on the channels we need. He coordinates with the contributors on his team to identify and solve issues as expected.

Are there any areas they could improve?

It would be hard for them to do things any better. The friction points we’ve had are related to our internal approval process. Some areas of the code can be approved by only a few people, so Tempesta has had to wait for that a bit. They could improve by learning our codebase better, but that’s a difficult ask. We’re happy as is.

Do you have any advice for future clients of theirs?

It’s important to provide good specifications and to communicate clearly and early.

Introduce your business and what you do there.

I’m the co-founder of an IT company.

What challenge were you trying to address with Tempesta Technologies?

We were looking to outsource the development of a module for traffic analysis.

What was the scope of their involvement?

We explained the way we wanted it to work, and Tempesta Technologies developed the module, fully implementing the functions using the programming language C.

The module does algorithms to analyze traffic, and it is connected to our web application. They currently continue to make modifications as requested.

What is the team composition?

We work with 3–4 people.

How did you come to work with Tempesta Technologies?

I met Alexander (CEO) at a conference. Tempesta Technologies is known for working in C, and they care about their performance.

How much have you invested with them?

We’ve spent less than $100,000.

What is the status of this engagement?

We began working together around May 2019, and it’s ongoing.

What evidence can you share that demonstrates the impact of the engagement? 

The metrics we track are confidential. They did meet milestones regarding schedule, and their code quality is good.

How did Tempesta Technologies perform from a project management standpoint?

There were a few meetings in the beginning to set the scope and milestones of the project. We communicate via Slack several times a week. They are responsive, meet deadlines, and communicate well.

What did you find most impressive about them?

Tempesta Technologies are experts in developing software in C with high performance, with no additional overhead allowed.

Are there any areas they could improve?

No, not really. They do very well.

Do you have any advice for potential customers?

Be aware that they are a small outsourcing company. They can’t easily scale up for large projects.

Introduce your business and what you do there.

We are a telecommunications company. We provide the industry with data services that they need for operations.

What challenge were you trying to address with Tempesta Technologies?

We were looking for a company to help us create new software for our telecommunications company.

What was the scope of their involvement?

We hired Tempesta Technologies to write some software for us which they did. They are experts in database technology, and we needed to build an extension for our MariaDB which is an open-source database. It was C code. After I tested and installed it on different computers. They fixed any issues that we came across. 

What is the team composition?

We worked with a manager and a developer.

How did you come to work with Tempesta Technologies?

I found them through a MySQL company. I sent them an email and described what I needed. They replied with a quote, and we went ahead with them. 

How much have you invested in them?

We spent less than $10,000 which was a bargain. If you had someone with the same qualifications in the United States, it would be more expensive.

What is the status of this engagement?

We worked with them in May 2020. It wasn’t a complicated project, so it took seven or eight days for everything to be tested and delivered. We are now in the production phase.

What evidence can you share that demonstrates the impact of the engagement?

The job was done perfectly, and we are very happy. We’re waiting for some regulatory things before we can put it out in the market, but from a technical standpoint, it is working well. We just have to get it to the market and until we get the green light from the government, we can’t do that, so we are waiting.

How did Tempesta Technologies perform from a project management standpoint?

The manager was in touch with me, and they passed on the requirements to the developer. It was smooth. They never objected to my comments or critiques.

What did you find most impressive about them?

I didn’t have to spend hours explaining what I needed. They just got it right away and they knew what to do.

Are there any areas they could improve?

No. 

Do you have any advice for potential customers?

I’d pay them double what they ask because they deserve it.
