This one completes it all - 32 hours of high-quality Spring full-stack web development

I am an Inflearn Green Coding instructor.

I have recently been taking on freelance projects.

I can develop any web page or web/app application for you.

Also, the admin page is included as standard. (Setup) => (Admin page, IP setup, security processing, etc.)

Outsourcing prices vary so much...

There is no reason for outsourcing costs to be so expensive.

Let me give you an example.

It is said that a certain blind date app commissioned an outsourcing project for 30 million KRW in 2024. (Image attached)

4.3 Spam: Since dating apps are categorized as such, on the App Store (iOS-iPhone),

In practice, the review was rejected, so the basic functions must be completely overhauled.

From what I can see, 7 million KRW is sufficient for the basic development cost, plus an additional 3 million KRW.

(Total 10 million KRW) is the appropriate amount to finally pass the 4.3 spam policy.

I believe this is the appropriate final amount required for that purpose (including the admin page).

(For reference, I am a solo developer who built and is currently operating a blind date app from scratch all by myself.)

Then why do other outsourcing companies usually say an average of 30 million won is needed?

The reason is labor costs. Since they hire employees for development, the minimum required amount is 30 million won.

In that case, the development period is set for at least 3 months. And for the launch, they allow about a month and a half for various tasks, so

they say it takes 6 months.

However, my personality is such that I prefer to focus and complete the project development in just one week, and then move on to the refinement work.

In my view, development will take about one month (for an app like Tinder), and I anticipate approximately three weeks for final refinements and launch.

So it will take about a month and a half to two months in total.

Also, the price is about one-third of the usual cost.

The reason that is possible is that it is both an advantage and a disadvantage, but

It is because I am developing it alone (as a one-person developer).

Then, if it's developed this way, will the app work properly?

Development is a skill. Ability is everything.

Additionally, I have already developed the admin page for a blind date app by myself and am currently managing its full operation.

I believe the proof of that can be found on Inflearn (a development lecture site) below.

Please take your time to think it over and consider it carefully.

hello.

The days are getting hotter and hotter.

About 20 students have taken the course in the past week.

Thank you for taking my React Spring Boot Full Stack course.

First of all, I would like to express my sincere gratitude.

First of all, all series lectures that will be uploaded in the future will have an unlimited subscription period!

Clap clap clap!!!

I've been worried. However, I hope I can help my students by not losing my original intention.

The upcoming docker aws github-actions course will also be available.

I am well prepared.

I think I'll be able to take the class at least by the end of August .

That's why it would be a good idea for our Inflearn friends to take the lectures in advance to become familiar with React and Spring Boot, and then take the Docker, AWS, and GitHub Action lectures.

I sincerely hope this will be helpful to many people.

Also, pre-course questions are now allowed as categories.

Since I asked you, please feel free to ask questions.

Starting this year, I will be working as a freelancer and starting my own business.

I think I'll concentrate.

May all your Inflearn friends be blessed in everything they do.
