// challenges_

Senior management team created frameworks and business plans for their new service platform, and their inhouse software architects and developers designed the basis and its plans.

The platform WARC envisioned required a large resources of full stack engineers, PMs, and DevOps. It also required a tightly running team working in high productivity as many other startups would do.

Given that the core competency of their business is not software development, realistically it would be difficult to attract talents quickly and efficiently. Among many alternatives they have decided to pursue embedding near or offshore development teams into their development team.

As their development team members had challenges in English communications, initially they have looked for resources in Vietnam where they offer N1 Japanese bridge SE, and quickly learned that bridge SE would become a communication bottleneck unless the bridge SE needs to be a superb PM before N1 Japanese skills.

The initial solution for Synca’s platform was developed in Golang and Vue.js. There was a lot of legacy code from the start of the project which was making performance and scaling problems. For a startup like WARC is understandable because they were in a testing phase and trying to find the best solutions for most of the features.

When Web Factory joined as an integrated part of their team, we immediately tried to help them stabilize the solution but after some consultation with WARC’s CTO we all decided that we should rework the whole solution from scratch.

We decided to go with Ruby on Rails as a fast growing and most famous framework to work with in Japan, great for prototyping and MVP. For the frontend part we stick to Vue.js as before. Together with the client we were building the system from scratch and we knew the end-goal, it was much easier to decide on many things during our journey about architecture, DB, and features.

Our team worked on the Backend solution for both B2B (and frontend) and B2C platforms, perfectly aligned with the WARC team that worked on the UI/UX product design, B2C solution and Synca cube.

It was critical at this stage to provide the best solution having in mind that WARC’s plans were to grow fast with new clients and businesses and so they did.

The infrastructure is set on AWS which is owned by WARCs team but supported by Web Factory’s DevOps engineers.

// solution_

WARC went through selection processes of choosing the right partner and had in depth discussion with Web Factory MK to see and evaluate the development skills, abilities and communication skills. Though it would mean the communication will be English based, WARC felt comfortable as the Web Factory MK side PM will own all communication within their side to avoid repetitive or lack of communication, so WARC will only need to communicate to a single point of contact. Also the team formation wise Web Factory MK proposed less head counts compared to others offshore developers as productivity levels are high and well organized team members.

Synca for Business, as well as Synca for Clients is developed in Ruby on Rails on Backend and the Frontend is developed in Vue.js. The solution for this application, offers not only job offers posting and resumes availability for the clients, but it is also calculating the matching rate between clients and companies, by taking into consideration different types of skills the users have, and the companies are looking for. Additionally, there is a possibility on the client’s side of the application, to calculate the minimum and maximum salary the client should expect by answering multiple questions related to client’s skills and work experience.


Layered architecture following domain driven design principles implemented in Rails.


Modular and flexible Vue single page application, built with TypeScript which enabled the creation of a well organized codebase following object oriented best practices.


Test cases and automatization is used in the testing process of the application, by previously analyzing requirements and creating test strategy.
