Performance icon

Web performance

Time and budget constraints during the MVP phase often mean compromises in the quality of the development. As traffic increases - performance often drops to disappointing levels.

Our approach starts with analyzing the code performance and identifying bottlenecks, also on production servers. Usually within just days we can offer quick fixes that significantly improve the performance. In the long run, we stabilize the performance on a high level via proper web application architecture.

App reliability

Our clients’ applications are reliable thanks to our policies of peer code review and additional quality assurance. By automated testing, bug reporting and application health monitoring we minimize the risk of products behaving in unexpected ways.

We also think of ourselves as reliable technological partners. We prefer to overdeliver on our promises.

Software maintenance

Overengineering an app means the architecture is too complex and the technology is too sophisticated for the web application purposes. Underengineering, on the other hand, leads to the technology being too basic for the sophistication of the product.

We achieve maintainability by building features with just enough complexity to meet the needs of users and leaving room for further expansion. We also automate tasks, track technical debt, choose widely adopted open source solutions and monitor bugs both in static code and live environment.

Web development costs

Old code, technical debt and outdated stack are difficult to expand, and extra effort involved becomes an interest the business has to pay. Technology locking is another problem.

We handle this by gradually paying off the tech debt and building new features in parallel, we maintain business viability and satisfaction of the engineering team. The seniority and maturity of our teams combined with automation improve the efficiency of the process.

Long time to Market

Your competition added new features and it would take months to catch up? That’s a pain for many scaling SaaS companies. However, a more flexible approach can easily speed up the time to market.

First, the feature we develop can be a basic prototype, that allows us to push it out faster, and leave deeper integrations and automation to later stages. Second, such a basic feature can be immediately tested to validate if the users actually take advantage of it.

User experience

User experience and customer satisfaction sometimes lag behind the overall functionality of the SaaS product. This is due to a lack of focus on user journeys, user flows and the design of the app.

A mature development team thinks both of the client and the end user. With small tweaks in UX, focusing on the features that really matter and continuous A/B testing we can achieve significant improvement.

Web security

Many applications are vulnerable to security breaches. They include identity thefts, personal data leakages through SQL injections and problems with authorizations, among others.

In the early stages of cooperation, we pay special attention to protecting applications against threats. We use penetration tests, web application firewalls (WAF), static code analysis, live code monitoring, etc.

Software scalability

In the post-MVP phase, businesses often want to scale the app and go global, but the technology behind the product is not ready.

The solution is to reject costly vertical scalability and promote horizontal scalability. With most businesses experiencing peak traffic and relatively calm periods, sensible management of resources is crucial for the profitability of the operation.
