About
I am an IT engineer and independent builder working to create systems that help reduce loneliness, emotional harm, and communication risk.

IT Engineer（infrastructure engineer）/ Independent Builder
My name is Naohisa Aoki, and I am an IT engineer.
I want to gently protect people’s hearts, and I aim to build systems
and mechanisms that help create a society where people are less likely
to be broken by loneliness.
To support this goal, I am developing the “Kokoro Mimamori” series,
a set of systems that support kind and considerate communication.
As the first step, I am currently working on systems to help address
defamation, power harassment, sexual harassment, and other forms of
harassment on social media and in everyday communication.
My favorite phrases are "Daiichi Daiman Daikichi" (meaning "One for all, All for one") and
"Sanpo Yoshi" (meaning "Good for the seller, good for the buyer, and good for society").
The following information is provided as my registered sole proprietorship details.
Kokoro Mimamori-kun and Kokoro Mimamori-chan are symbol characters who warmly express the values of Kokoro Mimamori and its gentle approach to communication.
They are intended to soften the emotional weight of difficult themes such as loneliness and isolation, helping visitors engage with them with a little more comfort and peace of mind.
Kokoro Mimamori-kun is inspired by a small shield that gently protects the heart.
He represents kindness, warmth, cuteness, and simplicity, reflecting Kokoro Mimamori’s aim to help people face words and information with a little more safety and peace of mind—without blaming or restricting anyone.

I have written more about my background and the thoughts behind “Kokoro Mimamori” on note.
One of my long-term goals is to help create a society in which people are less likely to feel isolated or emotionally broken.
I aim to build systems that make communication risks more visible and support gentler, more thoughtful interaction.
Words and expressions can encourage people, but they can also cause deep harm. That is why I want to use technology to create environments that feel safer and more supportive.
I value products that are understandable, calm, and practical. I try to avoid designs that create unnecessary pressure or rely on overly strong messaging.
Rather than forcing people into one way of thinking, I want to create systems that help them make safer and more confident choices.
I care not only about what a product can do, but also about how it feels to use it. Usability and emotional safety should work together.
My experience has been built over many years of practical work across infrastructure, databases, web systems, development, operations, and continuous improvement.
Over a long career in IT, I have worked extensively as an infrastructure engineer, supporting web services and business systems through planning, design, implementation, operations, and improvement.
My work has covered databases, servers, web systems, and operational processes.
I value systems that are not only technically sound, but also maintainable in practice.
Furthermore, in creating systems that protect people's hearts,
we handle every process from start to finish,
prioritizing the happiness of our service and system users,
eliminating sadness, and solving problems.
I have also been involved in areas such as project management, team support, governance, and budgeting. These experiences strengthened my belief that good systems should reduce burden, not rely only on personal effort.
My work is shaped not only by technical practice, but also by a long-standing interest in emotionally meaningful creation.
I have long been drawn to games, animation, manga, and other forms of creative work that can move people emotionally.
That interest still shapes how I think today. I want to build systems and products that are not only useful, but also calm, humane, and protective in the way they support people.
Through independent development, I continue exploring how technology, language, and thoughtful design can help create safer digital spaces.
This portfolio is a place where I share both the practical side of my work and the ideas behind the products I am trying to build.
