First, big thanks to the ADMIN for building this community. Really appreciate the work behind it. Happy to be here, and happy to contribute where I can.

Most of my work is with global clients, usually founders or companies building something with a real vision behind it.

Not really looking for one-off tasks only. I prefer working with people who want to build, improve, launch, and keep growing a product over time.

I’m based in Tokyo, Japan and work mainly across AI, full-stack development, SaaS, automation, mobile apps, and product development.

I also have access to active development teams and individual engineers here in Japan. So depending on the project, can support either a specific technical area or a full development process.

- Main areas I work in:

• AI agents and multi-agent systems

• LLM apps, RAG, AI search, knowledge systems

• Business automation and internal AI tools

• SaaS platforms

• Web applications

• Mobile apps

• CRM and booking systems

• Marketplace and matching platforms

• Logistics and dispatch systems

• GIS and location-based apps

• AI customer support systems

• Data processing and analytics

• Recommendation systems

• API integrations

• Cloud infrastructure and scaling

- Typical tech stack:

Frontend

React, Next.js, TypeScript, JavaScript, Tailwind

Backend

Python, FastAPI, Node.js, Express, Golang, REST, GraphQL, gRPC

AI / ML

PyTorch, TensorFlow, Hugging Face, LLMs, RAG, vector databases, AI agents, NLP, computer vision

Mobile

React Native, Flutter, Swift, Kotlin

Database

PostgreSQL, MySQL, MongoDB, Redis, Pinecone, FAISS, Elasticsearch

Cloud / DevOps

AWS, GCP, Azure, Docker, Kubernetes, CI/CD, GPU systems

- Have worked across quite a few industries too.

Healthcare, logistics, hospitality, education, finance, e-commerce, media, marketplaces, SaaS, customer support, field services, and more.

- I can also help with:

• Product planning

• Technical architecture

• MVP development

• Production development

• AI product strategy

• Workflow design

• Automation planning

• Scaling existing systems

• Legacy system improvement

• Team setup and coordination

• Long-term technical support

I’m human, so yeah, sometimes I can make mistakes too. What matters to me is how I handle them. I take responsibility, stay consistent, and put real effort into fixing things properly.

For me, trust is built over time. Not through one perfect delivery, but through steady work, honest communication, and being there when things get difficult.

That’s why I value long-term partnerships a lot. I’d rather build something meaningful with the same people over time than keep jumping from one short project to another.

Mainly interested in connecting with founders, business owners, developers, and teams who are seriously building something.

If you have an idea, an existing product, or a project that needs a technical partner, feel free to reach out.

Also happy to connect with other engineers here. If my experience or network in Japan can help, always open to a chat.
