I'm currently training to get AWS-certified in many areas. I've recently achieved the foundational AWS Cloud Practitioner certification and now moving on to the AWS Solutions Architect certification.

I'm a part-time IT and English teacher for students in Japan where I help them learn English from a technical environment. Our lessons range from the foundations of web design to deployment of full-scale web applications using modern technology. I also recently started freelancing as a full-stack developer at Changing Digital, a UK-based software development agency. I work with other developers to create websites for SMEs and large enterprises. Our stack includes React, Redux, Next.js, React Native, Github Actions, and AWS.

As a software engineer, my goal is to always keep learning in order for me to be able to create the most efficient and scalable applications possible. I make it my mission to continue growing and be a better person than I was yesterday.

When I'm not coding, I'm most likely learning a new language (programming or spoken!), hunting for freelancing gigs or listening to my books on Audible.

I wanted to learn how to integrate real-time communication in my apps. I used Socket.io to create a simple chat app in React. It was a little bit stressful learning this technology without having prior background or without any knowledge on where/how to get started but I made it work so it's a little achievement for me :)


I recently joined a website called devchallenges.io in the middle of the quarantine period in 2020. I wanted to test my Vue knowledge by creating web apps for the front-end path certification. It was really fun to make this!


I always record my websites to create tutorial videos for my clients. I previously used a third-party app but I disliked the watermark on the videos after recording. Which is why I decided to create my own free screen recorder. Many thanks to fireship.io.


I created a full-stack app for a client in Upwork. The client wanted to have a centralized webpage for their gigs. Functionalities included CRUD operations for gigs and the client's band of musicians had the option to accept or reject the assigned gig. Client requested to use the same hosting they used for their personal website so I decided to deploy the website on a subdomain.


I was hired to complete a job portal website by a friend. My task was to integrate the API to the client side. Integrated Employee and Employer APIs.
