Tech Lead at UMB Solution (ubitec)

Tech Lead was my official job title at ubitec. I have worked closely with two teams (7 developers in total) for developing two products ubichat and ubibot. My responsibilities were divided into three following roles:

- Software engineer: joined teams to implement/solve several challenging problems

- Technical consultant: for developers, Product Owners, Product Managers, and customers.

- Mentor: grew the teams in both technical skills and soft skills

Mental care

In my spare time, I enjoyed reading books and watching videos. I have been doing "meditation" in ... every moment in my life (no kidding 😊)

The following was my favorite 2021 Youtube channels:

- The Quoc Khanh Show Premium (TQKS Premium)

- Bar stories - Dustin On The Go

- Johnny Trí Nguyễn

Making life easier

This was a tough year due to COVID, however fortunately I could get my car driving license and buy a new house.

Happy new year, 2022!

Selenium - Override javascript functions to ignore downloading process

I have got an issue with downloading process on IE 8. This browser blocks my automatic-download functionality on my app so that I could not work with my test case any more after that. In my case, I didn't care about the file is downloaded or not, I just focus on the result after downloading process finished successfully. Therefore, I found a solution to ignore this process so that I can work normally. I use Primefaces, here is the remote command to trigger the download process <p:remoteCommand name="cmdGenerateDocument" actionListener="#{logic.onGenerateDocument}" update="xrflDocumentCreationPanel" oncomplete="clickDownloadButton();"/> The following is my test case: @Test public void shouldUpdateStep6ToWarningIfStep1IsValidAfterFinished(){ MainPage mainPage = new MainPage(); waitForLoading(mainPage.getDriver()); EmployeeDetailPage empDetailPage = new EmployeeDetailPage(); waitForLoading(empDetailPage.getDriver()); e...

Strategy Design Pattern

For example, I have a program with an Animal abstract class and two sub-classes Dog and Bird. I want to add new behavior for the class Animal, this is "fly".  Now, I face two approaches to solve this issue: 1. Adding an abstract method "fly" into the class Animal. Then, I force the sub-classes should be implemented this method, something like: public abstract class Animal{ //bla bla public abstract void fly(); } public class Bird extends Animal{ //bla bla public void fly(){ System.out.println("Fly high"); } } public class Dog extends Animal{ //bla bla public void fly(){ System.out.println("Cant fly"); } } 2. Creating an interface with method "fly" inside. The same issue to an abstract class, I force the classes these implement this interface should have a method "fly" inside: public interface Flyable{ public void fly(); } public class Bird implements Flyable{ //bla bla public void fly(){ System.out.pr...

Journal: This Month I Learned (2022-Nov)

This Month I Learned posts are aimed to share what I have learned during the month such as my thoughts, recommend resources, tips, how-to, and so on. Vung Tau beach Engineering Levels I conducted a lot of meetings with HRM to define the standards for evaluation criteria, career path ladder, Personal Appraisal (PA) processes, and onboarding/offboarding processes. I knew more about the expectation from an HRM perspective for engineering levels evaluation criteria. For example Define many enough titles for a long career path development Define general criteria for each level How to calculate score when evaluation with weight matrix applied Anticipate risks before executing a process Team Engineering Lead Organization I collected ideas from different people When having no dedicated leader, every member of the team has a fairly chance to practice leadership skills Scalability strategy: development teams’ size, and new position nomination. Security Awareness Training I conducted this sharing...

Installing NGINX on macOS

I have heard of a lot of NGINX recently. One of them was it can help for security issues; for sure, it much be more. It so happens that our team has got a ton of user stories from a security audit. It's time to delve into it. What is NGINX? In order to get a basic idea and have some fun , I've just picked some available posts from my favorite Vietnamese blogger communities as below: https://kipalog.com/posts/Cau-hinh-nginx-co-ban---Phan-1 https://viblo.asia/hoang.thi.tuan.dung/posts/ZabG912QGzY6 NGINX (pronounce: Engine-X) is a web server (comparing to IIS, Apache). It can be used as a reverse proxy ( this is what I need for security issues with configuration ), load balancer and more. How to get started? I found the below path for learning NGINX by googling "learn nginx": https://www.quora.com/What-are-some-good-online-resources-to-learn-Nginx In this post, I only went first step. This is installing NGINX on macOS and taking a first look at the confi...

Automating deployment and managing apps on OpenShift

Previously, we maintained OpenShift templates for deploying apps in development environments as well as delivering these templates to our customers for their on-prem deployment. Customers who refer to our templates (as well as documentation) have their own configuration management tools to automate the deployment such as ArgoCD and FluxCD. My son's buildings Our developers usually modify templates (YAML) directly on OpenShift for testing and then adjust the corresponding templates stored in the Git repository in Bitbucket. This sometimes causes an issue that delivered templates are incorrect because: - Developers forget to update the templates in Git repositories. - Developers don’t test the templates Therefore, our goal was to integrate a tool into our CI/CD that can automate and manage the configuration of OpenShift apps. The delivered templates should be the ones that are able to run on our OpenShift with the following purposes: - Automate deployment from templated in Git repos...
