FAQs: Technical due diligence

Our technical due diligence consulting services provide a comprehensive assessment of your technology stack and systems, focusing on code quality and adherence to best practices, architecture and infrastructure scalability, data strategy alignment with business objectives, and security protocols. We evaluate your DevOps practices, including automation and disaster recovery plans, along with the effectiveness of your QA processes and the agility of your SDLC. By examining team dynamics and product team involvement in software delivery, we identify potential challenges and areas for improvement, ensuring your technology infrastructure is robust, efficient, and poised for future growth.

We work on a time and material model with daily rates. You only pay for the time our experts dedicate to your needs. Depending on your needs and requirements, we can set up the consulting collaboration on an ongoing part-time basis or as a shorter, fixed-term consultation. Once we have gathered enough context, we can provide an estimate of the expected duration and resources necessary for fulfilling your requirements.

The duration of a software development consulting project can vary depending on your needs and requirements. There is no minimum time commitment requirement for our consulting collaborations, which vary from a few working days to several months on an ongoing part-time basis.

We have provided software consulting and development projects across multiple industries including fintech, edtech, medtech, renewable energy, telecom, e-commerce, automotive, travel, media, logistics and fulfilment technology. We understand the varying demands of different sectors, including the heavy regulations and compliance requirements in some. To that end, we are ISO 27001 certified and place a strong focus on security and compliance.

We have deep expertise across most common technologies, including, but not limited to JavaScript/TypeScript (React, Angular, Vue.js, Node.js), .NET, Java, Python, Scala, Golang, and in cloud technologies, such as AWS, GCP, and Azure.

Here are the three areas we believe make us a strong software development consulting company and a valuable partner.

Our Technical Expertise and Flexibility

Our team of subject matter experts, led by our CTO, have expertise across a wide range of technologies and sectors. We understand the requirements, both technical and cultural, of a small company building an MVP are different from those of a large multinational firm, trying to modernise or consolidate its technology stack. We understand the regulatory requirements of various industries, and that guides our technological decisions. We aim to understand your needs – current and future – and set up a collaboration that will ensure we bring the most value to your business.

Company Values and Culture 

When it comes to choosing our partners for software development and consulting projects, we only take on good clients with interesting projects, who believe in treating people respectfully, and who focus on working to high standards. Engineers enjoy working at Zartis, as evidenced by our 4.9/5 rating on Glassdoor after 80+ reviews. In the fourteen years we have been in business, we have consistently worked hard to live up to our values, and to continually improve as a company.

We Tell the Truth

If there is an issue – a problem, a delay, or a setback – we work actively to solve it collaboratively with our customers. Our clients trust us, not because we are perfect, but because we believe in being upfront, and not hiding small problems. This makes it easy to partner with Zartis, and is one of the reasons that our customers stay with us in the long term.
