Our Tech Stack

Maf.ad is a cloud-native, event-driven ad network and offerwall platform deployed across a hybrid infrastructure spanning Google Cloud and Microsoft Azure.

The backend—comprising REST and GraphQL APIs, along with our core event-tracking pipeline—is implemented in C# on the .NET framework.

Our web applications are developed in TypeScript using Lit, a component-based framework aligned with modern UI development standards and comparable to widely adopted frameworks such as React, Angular, and Vue.

For analytics and reporting at scale, we leverage Google Cloud’s big data stack: BigQuery as our primary data warehouse for fast, SQL-based insights over large volumes of event data, and Bigtable for high-throughput, low-latency access patterns on time-series and event-driven datasets.

What you'll bring to Mistplay:

• Bachelor’s degree (or higher) in Computer Science, Engineering, or a related field.

• 3+ years of professional experience in software development.

• Strong proficiency in one or more programming languages such as C#, Java.

• Experience with backend frameworks and RESTful API development.

• Solid understanding of database systems (SQL and NoSQL) such as Sql Server, BigQuery, BigTable.

• Experience with cloud platforms (e.g., Google Cloud, AWS, Microsoft Azure) and containerization (Docker, Kubernetes).

• Problem-solving mindset and a passion for building high-quality, scalable systems.

• Excellent communication and collaboration skills.

• Fluent in English (written and spoken); additional languages are a plus.
