Description

I am a passionate developer with a unique background that bridges science and technology. I graduated from Nagoya University with a major in organic chemistry, where I focused on asymmetric carbon synthesis using organic molecular catalysts. This training sharpened my analytical skills, problem-solving mindset, and attention to detail, which I now apply to software development.

At 31, I was diagnosed with ASD, a turning point that helped me understand my strengths in logical thinking, precision, and creativity. My journey into programming began in a welfare facility, where I discovered how coding could be both empowering and transformative. Since then, I have worked for an IT company for a year and a half, gaining practical industry experience, and then dedicated another year to independent development, where I created real-world solutions from scratch.

Currently, I am developing an end-to-end, low-latency real-time remote desktop application that achieves around 50ms delay in a fully local environment. This project combines my expertise in system optimization, GPU programming, and network efficiency. I am also initiating the development of GPU-based Forward Error Correction (GPUFEC), which has the potential to redefine performance standards in high-speed communication and streaming applications.

Beyond technical expertise, I bring diversity and perspective as a queer professional. My identity as a gay individual gives me a strong sense of inclusivity and resilience, values that I carry into collaboration and problem-solving.

I can support projects that require high-performance software, GPU acceleration, real-time processing, or innovative solutions at the intersection of hardware and software. I am also comfortable with independent research and development, building systems from the ground up, and optimizing them for stability and speed. Clients can expect clear communication, dedication, and results that are both technically solid and forward-looking.

December 2022 - January 2025 (2 years and 1 month)
Ōgaki, Japan
At Sowel Inc., I worked as a software engineer under a diversity and inclusion program, contributing to both internal tool maintenance and the development of an energy storage management system.

C/C++ Internal Applications: Maintained and improved proprietary in-house applications, including the company’s internal chat system. I added new features, resolved critical bugs, and optimized performance, directly improving the work environment and communication efficiency across teams.

Python Energy Storage Management System: Contributed to the design and implementation of a battery management system. I developed communication modules between server and client software, ensuring reliable and scalable data exchange.

Web Management Interface: Collaborated on the Flash-based web administration console, enabling real-time monitoring and control of battery systems.

Through this role, I strengthened my expertise in C/C++ for application maintenance, Python for backend system development, and cross-platform integration. My work improved both the company’s internal productivity and the reliability of its energy infrastructure solutions.

In addition, although I am on the autism spectrum (ASD), I have successfully engaged in collaborative team development. This experience taught me the importance of aligning directions within a group, communicating effectively, and contributing to shared goals. My former manager commended me for being highly skilled in programming, delivering work both quickly and with great attention to detail. I believe these strengths will allow me to contribute significantly to your company—whether in testing and debugging products, improving existing systems, or building new solutions from the ground up. I am eager to bring both my technical expertise and collaborative mindset to support your projects and help ensure their success.

January 2022 - Today (4 years and 5 months)
Gifu, Japan
Designed and developed advanced GPU-accelerated applications and real-time streaming prototypes, demonstrating strong expertise in high-performance computing and low-latency system design. My personal project, a custom-built remote desktop solution, achieved an exceptional ~50ms end-to-end latency at 4K resolution — a level of performance rarely seen even in commercial software.

In addition to real-time streaming, I built automation tools and testing utilities for small businesses and personal projects, ensuring improved efficiency, reliability, and scalability. These experiences highlight not only my technical abilities but also my capacity to deliver practical solutions tailored to real-world use cases.

I have extensive knowledge of CUDA programming, DirectX 12/11 screen capture, and GPU-based video encoding/decoding using NVENC. This combination of skills enabled me to implement optimized data pipelines with UDP + Forward Error Correction (FEC) for stable, high-quality transmission, as well as sophisticated inter-process communication mechanisms.

With this background, I can contribute to your company in several impactful ways. My expertise in CUDA and GPU acceleration is rare in the current job market, positioning me as a strong asset for projects involving real-time remote desktop systems, streaming platforms, or innovative multimedia applications. Furthermore, my ability to work with both high-level development (Python, PHP) and low-level GPU programming allows me to bridge the gap between application design and performance optimization.

I believe these experiences would allow me to contribute significantly to the development of next-generation software at your company, particularly in areas requiring real-time responsiveness, robust system design, and advanced GPU utilization.
