Local produce, global outreach

Transforming challenges into breakthrough digital solutions. Proven strategies that drive performance and innovation.

Our client, backed by SoftBank, operates a global food trading platform that connects international buyers with Japanese food producers.

The legacy system, built on outdated Java Servlets, struggled with scalability, maintainability, and user experience, limiting the client’s ability to meet rising global demand. The client sought a partner who could maintain business continuity while completely rebuilding the system for the future.

Challenge

The project presented significant hurdles:

Undocumented Legacy System: No documentation existed, making it difficult to maintain and enhance.
Outdated Technology: The Java Servlets-based platform was rigid, unscalable, and costly to update.
Continuous Operations Needed: The client required uninterrupted services while modernization was underway.
Inefficient Search: Users struggled with a slow, inaccurate search experience.
Global Accessibility: Multilingual support was essential to serve international markets effectively.
Tight Timelines: A complete system renewal had to be delivered within a year.

Approach

Strategic Collaboration and Reverse Engineering

Global Teamwork: Distributed teams in Japan and India collaborated seamlessly with the Tokyo-based business unit. Face-to-face workshops and frequent online syncs aligned requirements and goals.
Reverse Engineering: With no documentation, we meticulously analyzed the legacy system to identify core business logic and workflows.
Dual-Team Model: One team maintained the legacy system while another rebuilt the new platform — ensuring uninterrupted business continuity.

Agile Development and Execution

Scrum & Agile: Iterative development cycles with continuous feedback loops allowed rapid adaptation to evolving requirements.
Resource Flexibility: Team sizes were scaled dynamically to meet project demands while optimizing costs.
On-Time Delivery: The complete system rebuild was executed within one year despite high-pressure timelines.

Technical Innovation

System Rebuild: Implemented a new architecture with Spring Boot (backend) and React (frontend), enhancing scalability, maintainability, and performance.
Enhanced Search Engine: Integrated PostgreSQL with advanced indexing to deliver a faster, more accurate search experience.
Multilingual Support: Enabled producers to input product details in Japanese with automated translations for global buyers, plus a back-office review process for refinements.
Future-Proof Design: Built a modular architecture that supports easy scaling, integration, and feature expansion.

The Transformation

The transformation delivered measurable impact:

Reduced Maintenance Overhead by 60% through a modern, efficient architecture.
User Engagement Increased by 45% with a streamlined UI and optimized search engine.
Scalability Achieved: The new platform handles 3× the previous transaction volume.
Global Reach Expanded: Multilingual support drove a 30% increase in international user registrations.
Business Continuity Ensured: Zero downtime during transition maintained trust and revenue flow.
On-Time Delivery: Full rebuild completed within one year, meeting all client expectations.

Testimonials

What it’s like working with us

"Building a business from scratch (before TypeGO is fully formed and accepted in market) and reaching the point where customers come on board and revenue is generated is never an easy path. As you also know it often requires breaking what has already been built over and over again, and sometimes even making major pivots in the business. Throughout that process, OP team has stayed close to us and helped establish a development structure that allowed us to stay focused on building a product true to our philosophy. For that, I am deeply grateful.

Because we trust completely that "anything can be done and deployed," without worrying about whether it is possible or not, we are able to concentrate our thinking on one thing only: what makes a truly great TypeGO. So again, thank you always!!"

"We worked with ONEPIXLAB on a backend engineering project for our startup's Android app. From the start, they were highly engaged and collaborative, assigning a scrum manager, a project manager, and a developer, while also bringing in additional team members who actively participated in discussions.

They didn't just take requirements at face value. They helped brainstorm, challenged assumptions, and worked with us to shape the right solution. Their focus on quality, communication, and thoughtful execution made them feel like a true engineering partner rather than a typical outsourcing team."
