Things I want to learn

I have been fortunate enough to learn many things throughout my career, but I still have a long way to go. This is a list of some of the technologies that I would love to learn.

Frequently Asked Questions

Here are some frequently asked questions. If you have any other questions, feel free to contact me.

  • Where can I see your professional work?

    Thank you for asking! For full transparency, I am unable to show my best work publicly because they are locked behind non-disclosure agreements. If you contact me however, I will be able to share them with you in private during the call.

    If that is not enough for you, I am happy to report that this entire website that you are in, is designed, crafted and fully built by me using Nuxt and Tailwind CSS (JamStack Hosted), and thus can be considered as part of my professional work. I hope that it is satisfactory to your liking 😊

  • How much does it cost to get started?

    It will depend upon the scope and requirements of the project. For reference, past projects have ranged between $30 - $40 (hourly, 40+ per week).

    On the call, we will seek to identify specifics and objectives that can affect the cost. These are things like what type of project, which tech stack to choose, timeline, complexity, frontend/backend/fullstack, etc. All these will contribute to the cost and will vary from project to project.

  • How long will the work take from start to finish?

    It will depend on the scope of the project.

    • If it is a frontend application, it will take less time.
    • If it involves complexity with backend stack, it will take slightly longer than before.
    • For fullstack applications with both frontend, backend, database, etc, will take longer time. A previous project of mine took almost 1200+ (6+ months) hours to complete including deploying to production server.
    • For mobile applications, if it requires an API to develop, then the time will be as equal as the previous one.

  • Do you offer any deployment services like Docker, Kubernetes, AWS/GCP/Azure, Heroku, VPS, Static/Shared Hosting, etc?

    Yes, I do. If you need any of these services, I can do that for you after finishing the development and testing phase.

  • Do you offer any maintenance services in the future after the project has been finished?

    Yes, I do if it is a major breakdown. However, I may charge additional fees according to your requirements and maintenance workload.

  • Can you help me to grow my own startup?

    Yes, of course I can. I have already worked with some startups, building their ideas into reality. I also worked as a project manager in my previous company that I worked with. From building a Minimum Viable Product (MVP) to launch and growth, I can help you in each step.

  • Do you have any agency or team to work with you?

    Yes, I have a team of 5 members who are experts in their own field. We're working together for the last 3 years. Moreover, we are planning to expand our team with an agency in the near future.
