4 min readAug 5, 2022


Here comes another story from our employees — Sertizens. This month, we would like to introduce you to James, our long-serving Senior Software Engineer who plays an important role behind one of Sertis’ flagship products, Sertis Face Scan. He has succeeded in developing and creating Sertis’s model with our own software with his expertise and the support of Sertizens including the AI Research team, Machine Learning Engineering team, and Software Engineering team.

He also tells us what it is like to work in a collaborative environment, what saves him to overcome challenges, what the most important thing is to achieve a career path as a software engineer, and he also gives exclusive advice for anyone who is interested in joining Sertis.

1. Tell us about your journey at Sertis

My journey at Sertis has been similar to my journey through University, in terms of groups of people who come from different places with a variety of unique skills. The work experience is similar to a group of friends working together, helping each other, and growing together to overcome exciting and challenging projects.

2. Comparing your Day 1 to present

Day 1, I was just a fresh grad with only the fundamentals. Imagine that, going from doing homework, reading books, passing exams; to working and delivering the best of what you can do for customers. I could say, at the time; I was a bit stressed and nervous.

But having my colleagues (Sertizens) saved me. We helped each other, learned, and improved our work together. Just like we learn, and implement everything with friends in the same classroom. We also have a tough time together but in the end, we deliver the best solution to our customers. I could say, I have improved myself a lot in terms of knowledge and skills that every developer needs to have to achieve in their career path. Not only in the Software Engineering scope such as Node.js, Elixir, Python, React, etc., but also in DevOps (GCP, AWS, CI/CD), AI Model, and MLE.

3. Your most proud of initiative

In 2019, Sertis started working on a Face Scan product. So we created a power team joining forces with AI, MLE, and SE to brainstorm and create our own AI model, SDK, and services including website and software. As a developer, we needed to design the whole architecture from scratch. Communicating and collaborating with the AI and MLE team every day to make the software and website compatible and work smoothly.

The challenges at that time were the AI and software parts; we had very little experience and knowledge of Face technologies including model, software, or even hardware to work with. We researched, implemented, and tested our product over and over, until we succeeded in creating our own model with our own software. Our very own product, Sertis Face Scan.

4. The best thing about working at Sertis

Having the chance to work in a collaborative environment, and always communicating with each other. We share pain points, experiences, and knowledge together. We believe that sharing all of these things will make us stronger with a more positive mindset. This is what makes Sertis a resilient and adaptable company.

5. Any advice to Sertizen new joiners

We have a lot of products and software that are available for everyone to have a chance to learn and improve and become a skillful developer. Don’t think too much and don’t underestimate your abilities. Be yourself, keep in mind there is nothing you can’t do if you set your mind to it; especially true when you have like-minded people, anything is possible to accomplish.
