Introduction
Nice to meet you. I am FreeLike.
I am a freelance engineer (in my 4th year as a sole proprietor) specializing in embedded software development for medical devices.
In this note, I share the reality of the medical device industry, the structure of the IT industry and SES, and lessons in business management as a freelancer.
This article serves as a "guide map" for my note.
I hope you will read from the topics that interest you.
About Me
FreeLike | Representative
I have been involved in embedded software development for medical device manufacturers, such as patient monitoring equipment. I specialize in C/C++ and Windows embedded environments.
Beyond medical devices, I have experience developing high-reliability systems for railways and automotive applications, where "if it stops, it affects human lives and livelihoods". I currently have about 10 years of engineering experience.
I am currently supporting clients through quasi-mandate contracts while advancing my business on both technical and management fronts.
Certifications
IT Coordinator (ITC) ── A national certification that bridges management and IT
Applied Information Technology Engineer
Fundamental Information Technology Engineer
Python 3 Certified Engineer Basic Exam
By obtaining the IT Coordinator certification, I have become an engineer who can offer a perspective of "Management x IT," rather than just "technology alone."
* The story and background leading up to my independence are summarized in the following article.
Why I write this note
The catalyst was two books.
"The Thinking Method of World-Class Engineers" by Go Ushio and "In the End, Life is Determined by Output" by Satoshi Nakajima.
Encouraged by these two books, I decided to put my own experiences into words.
The field of embedded software for medical devices has very little information available online.
It is a world that cannot be known from the outside unless those within the industry share their knowledge.
That is precisely why I want to convey the reality of the field, clearly and honestly to you.
Article Categories
In this note, I write articles based on three main themes.
1. Medical Device Industry
I explain the structure and characteristics of the medical device industry from the perspective of a field engineer.
I have organized the overall picture of the industry into 12 points, such as it being a growth market, the prevalence of small and medium-sized enterprises, and the high barriers to entry due to regulations.
※ This article was featured in the 'Money' category on note.
2. IT Industry and the SES Business Model
I explain things that people working in the IT industry should know, such as how SES works, using diagrams.
I will share information about the SES business model based on my experience as an independent freelancer.
3. Lessons as a Business Owner ── SMG Management School Report
I am participating in the SMG Management School hosted by YouTuber 'Datsu-Zeirishi Sugawara-kun'.
I summarize what I learn at the monthly regular meetings in report articles.
I have summarized my learnings from M&A/DD basics, tax saving strategies, and marketing lectures. This was the turning point where I decided on my positioning in the 'medical device industry'.
My Career Story
After graduating from university, I joined an IT company and gained experience in embedded software development. I became independent while carrying about 1.5 million yen in debt upon resigning, and I am now in my 4th year as a freelancer. I am conducting my business by focusing on the specialized field of medical device embedded systems.
The twists and turns leading up to my independence—my time in SES, contract troubles, utilizing public systems, and encounters that changed my values—are all written in my self-introduction article.
