Design, development, and operation of HTTP API development (REST/GraphQL/gRPC), web application development, in-house systems, and Android/iOS application development. Pipeline development for integration between SaaS is also possible. Please contact us for other SaaS such as Firestore, SalesForce, Slack, Chatwork, etc. Service: https://www.ractdev.moff-bear.com

Security ~ Security Diagnosis

We conduct Web API vulnerability diagnosis, web application vulnerability diagnosis, and infrastructure vulnerability diagnosis. We evaluate vulnerabilities such as diagnosing the application of authentication and authorization, diagnosing used packages, and diagnosing access to networks and data, and provide reporting. This service aims to prevent cases such as delisting due to information leakage and service suspension due to frequent unauthorized use.

Infrastructure and DevOps

We perform infrastructure design/construction and service operation. We will construct a configuration that meets the requirements of customers such as serverless, VM, and container, and operate it safely including data store. We can also consult on cost emphasis or performance emphasis.

SRE Consulting

We support a wide range of areas including strategy formulation, design, construction, and operation of system scalability. We will assign professional personnel to support the introduction of public cloud, microserviceization, containerization, introduction of Kubernetes, and support for CICD/GitOps.

Any Programming Language

We will select the best programming language tailored to your project requirements and develop accordingly. Development in specified languages is also possible.

Custom Infrastructure Design and Setup

We will design and set up infrastructure tailored to your project requirements, ensuring safe service operation.

Service Security Assessment

We will diagnose vulnerabilities in your service and support the release of a secure service.

Migration to Cloud Systems

We will migrate to GCP, AWS, or Azure, selecting the best options for our clients, including serverless and container solutions.

Kubernetes Adoption

We will containerize your applications and set up Kubernetes clusters. Additionally, we can introduce Cloud Native Foundation OSS that works well with Kubernetes.

Flexible Consulting

We support the introduction of solutions to address challenges in various industries.

Examples of issues we can solve

We want to help make technology available to all industries. Our highly skilled members will help customers solve their technology problems.

  • Q: Due to a shortage of engineers, I want to outsource some functions or systems.


    There is a shortage of engineers, causing delays in release timing for WebApp/system/mobile app development. Challenges arise in management and quality assurance due to the utilization of external resources such as part-time talent and outsourcing. Additionally, each development is tightly coupled, and there is a desire to develop with loose coupling to increase speed.


    Answer - Our Suggestion

    We will support you in developing with loose coupling according to your requirements. Additionally, by introducing test code and automated testing, we will continuously deliver stable deliverables. This ensures the delivery of additional functionality. We also provide support for subsequent product operations and more.

  • Q: I have an idea and want to request design and development.


    There is an idea for a service, and the business organization is in place, but the engineering organization has not yet been established. Therefore, I want to request design and development. I also want to discuss how to operate it after development.


    Answer - Our Suggestion

    Our team consists of members from well-known tech companies, so we have excellent technical capabilities. Depending on the scale of the service, we can quickly and with high quality, rigorously listen to your ideas and develop them into services. Additionally, in zero-based development, we can handle everything, so we will design and develop to meet your requirements while listening to your future service scale.

  • Q: I want to migrate existing systems or core systems to the cloud and modernize them.


    I want to rebuild our legacy system. Additionally, I want to migrate it to a popular public cloud. When migrating, I also want to discuss authorization management and other matters.


    Answer - Our Suggestion

    Our team includes engineers with experience at foreign tech companies in SRE roles, so we will handle the migration of legacy systems with a medium to long-term perspective. We will migrate while strictly managing security and permissions to meet the service requirements, discussing the best approach for migration.

  • Q: I want to develop a system/service integrated with SaaS (Stripe, SendGrid, ChatGPT, etc.)


    I want to improve the quality and efficiency of services integrated with SaaS. I want to migrate our in-house systems to SaaS-based systems and decompose responsibilities.


    Answer - Our Suggestion

    Since SaaS APIs generally adhere to standard REST API specifications, it is possible to develop integrations with any SaaS. Our team can handle development even for technically challenging projects, enabling integration based on SaaS documentation and requirements.

Reasons to Choose Us

We specialize in technical expertise. By focusing on technical expertise, we can develop projects considering the merits and demerits of each, such as prototyping development emphasizing speed, development resilient to changes requiring constant traffic and long-term scalability, and development capable of handling high traffic. Additionally, we develop considering the trade-offs of technologies used according to your requirements (compiled language/scripting language, SPA/SSR, CAP theorem/ACID properties, Docker/VM/serverless, etc.).


Development examples

These are examples of web application, infrastructure design/construction, and mobile application development that we have assisted in the past. We can develop web applications such as matching sites, industry-specific SNS, and SaaS, and can also construct technology-driven infrastructure. In accordance with customer requests, we use our high technical capabilities to provide software design and development, infrastructure construction, operation/SRE consulting, and DX support. You can check many examples from here.
