About

Who am I - What do I do - What do I like

Who I am

My name is David Tchekachev (a.k.a Tchekda on the Internet) and I'm a cloud-native software engineer focused on distributed systems, microservices, scalable architectures, and technical leadership.

Currently available for freelancing (now) or internship/full-time position (starting from Feb 2026). Resume available here

In various projects, I architect, develop, and deploy solutions for companies, NPOs, and side projects. My objective is always to provide the best technical solution that meets the client's needs, while being performant, cost-effective, and simple to understand/maintain in the long term.

I also engage in sport and volunteering activities in order to build new non-tech skills that I can use for my professional experience. Keeping myself busy to get better and more valuable is one of my most important goals.

Soft skills

How do I work with other people - What makes me different

What makes me better at what I do

  • My experience in ice-hockey refereeing forced me to master some skills such as communication, conflict management, teamwork, stress management, decision-making, openness to criticism, leadership and many more because I need to take decisions in the matter of a second while managing players that are competing at full speed. I also heavily rely on my colleagues as much as they rely on me to take the best decisions from the points of view we each have and take a step back to quickly analyze tense situations.
  • As a freelance, working with real clients taught me some other skills which helped me gain a lot of experience, for example adaptability, leadership, creativity, time management, project organization, specification formalization and problem-solving are skills that helped me a lot to successfully answer client's needs by providing custom solutions that fit perfectly the requirements provided.
  • As a team leader, I discovered a lot of new aspects that are helping me efficiently manage my teams by developing a variety of skills like project management, collaboration, decision making, communication, leadership and many others valuable keys to create the best environment for my colleagues and I to work in.
  • Being curious is keeping me interested in the new solutions used on the market that could allow me to build new projects in the future. When I want to solve a challenge, this allows me to take a step back and research what is already available out-of-the-box to use, instead of building everything from scratch, and then make the best recommandation to my clients with the most time-and-cost efficient proposal.

What am I doing else

What I'm doing for others and our society

Outside of my studies and sports activities, I also like to volunteer on my freetime, in areas I am passionate about. It allows me to try new things in a friendly environment, without any professional expectations.

Being a self-taught developer, I wished so many times to have someone to help me and guide me in my learning process, so I decided to give back to the community by helping students in their learning process. I started by leading workshops at CoderDojo Paris, and later join Prologin / GirlsCanCode (national organization)

I have developed a passion for aviation which led me to buy a Flight Simulation software and join an online network, IVAO.aero. One thing led to another and I ended up joining the organization's Web Dev team, after some years I took over the leadership of the team and now I am in charge of a team of 10 developers, working on the various projects. Applying my tech skills to the aviation world is an awesome opportunity.

In 2024, Paris hosted the Summer Olympics & Paralympics; since I didn't only want to spectate and wanted to contribute as I could to the event, I applied to be a volunteer. I requested to be placed at a leadership position and was assigned to co-lead the Olympic & Paralympic Family Assistant teams (300 volunteers each). I quickly proved myself valuable and trustworthy within the organization, and was given additional responsibilities to support the operations and ensure smooth coordination between the various parties attending the event.

Tech Writer

Technical Writer

Since 2025

When working on cool projects, I would always be proud of the challenges that I/we faced, and would share them with my friends group. Writing public blogs allows me to share them publicly, while helping other developers, and providing insights to my clients on the work being done. I enjoy writing mid-length articles to present the interesting tech details, while not being too dense or boring.

IT M&A

Deloitte Paris

Sept 2024 - Jan 2025

After completing my Bachelors degree and before starting my Masters, I wanted to discover real-world entreprise IT architectures to grasp a better understanding on how they operate. By joining Deloitte's IT M&A team, I was able to work with various companies while developing my formalization and analyzing skills. While I was providing tech expertise, I was also given the opportunity to autonomously lead a small Due Diligence project thanks to the trust built with my team.

Deloitte Luxembourg

June 2023 - Aug 2023

During a summer internship at Deloitte Luxembourg, I lead the development of an internal application in coordination with the UI/UX team while reporting to the company's stakeholders. This project was a great opportunity to learn how to work in a big company and how to manage a project from A to Z.
Also, I had the opportunity to drive some research on Generative AI and how it could be used in such big company.

Working for this company allowed me to touch a lot of different technologies and new things I wouldn't have thought of, such as BigData, Influencer Marketing, Mobile Application, Blockchain, Medical products, E-commerce, AWS at scale, etc...
