How we work

We follow Agile software development methodology and build trust-based partnerships with all of our clients.

Discuss

What is your app's main value? What are your business objectives? Any third-party solution you'd like to integrate with? We need to have a clear picture of what you have in mind. As a result of this stage, we will provideyou with a bare scope and cost estimations.

Strategize

Strategizing includes drawing a mind map, writing use cases, designing user flows, defining technology stacks, preparing test documentation, and more. You'll get a precise scope and cost estimations and a product development roadmap at the end of this stage.

Iterate

We organize our process in two ways: Scrum or Kanban. Kanban is greatfor projects that require flexibility. Scrum works best for projects with a precise scope. We follow a continuous delivery approach with dailymeetings and demos at the end of each iteration.

Improve

After we launch your product, we can help you maintain and support it.Our support activities include 24/7 critical bug fixing, stability monitoring, internal engineering team coaching, protection from security vulnerabilities, and planning new releases.

Our core technology stack

Our core tech stack includes Go, React, Swift, and Kotlin –something that was invented less than a decade ago.

The best way to build simple, reliable, efficient, and secure backend with concurrency support in its DNA. 40% faster than Node.js.

React

Modern, component-based frontend development with TypeScript. Complex SPAs, admin panels, and enterprise dashboards.

AWS

Cloud-native infrastructure expertise. From ECS/EKS to Lambda, we architect scalable, secure, and cost-efficient platforms.

Kubernetes & Docker

Container orchestration for enterprise-grade deployments. Zero-downtime releases, auto-scaling, and infrastructure as code.

Never say "impossible"

We don't have any bans at MadAppGang. Except one.The phrases "this is impossible," or "I can't do it" are prohibited. We do research, suggest solutions, and evaluate these solutions. Then we come up with a decision on how to achieve the desired outcome. We never say "It's impossible."

Be your own boss

Being your own boss means taking responsibility for your own actions. We don't make others do our job. And we don't rely on managers with inflated corporate titles to make things work. We brainstorm ideas and generate solutions. If we need help, we raise the issue and solve it within our team.

Challenge yourself

Everybody at MadAppGang has one common trait: a strong desire to learn. Personal development is about challenging yourself. You can never see any improvements if you stick to your comfort zone. If you stop growing, you drown. We prefer to keep moving than to stay still.

Embrace the new

We stay ahead of the curve. AI and machine learning, blockchain, and IoT – we have experience in all of these areas. We learn new technologies because they help our clients create better products (and out of pure curiosity). We're small but we move faster than others.
