Estafet Bulgaria

The company'skey products and services are:

• Development & Integration - the core of Estafet's business model is the integration of multifunctional systems. We use microservices as a leading architectural solution to achieve high performance, scalability and resilience. Through them we have the ability to decompose business domains, which in turn would enable integration at a very low inter-component granularity. The microservices architecture solution allows us to easily implement key concepts such as Event Driven, Streaming and Restful. We build in depth with monitoring and analytics systems. At Estafet, we are focused on deploying microservices in "Platform as a Service" (PaaS) virtual container-orchestration environments operated by leading global cloud service providers (AWS, Azure, GCP). We use back-end programming languages (Java, Scala, Python, etc.) for their development. At Estafet, we have empirically found that following a development methodology greatly aids in the successful completion of projects. Agile methodology has been established as the leading methodology and followed by us in implementations of Scrum, Kanban, SAFe®️ etc.

• For Estafet, QA is not just another "check mark" required for a project - QA is a process and mindset embedded in our company values. Our Quality Engineers ensure that everyone is actively engaged in how we build and test our products, how to implement new and improve old quality processes. Our primary focus is on automated testing - we design and implement end-to-end automated testing solutions, and our core technology stack includes (but is not limited to) Java, Git, Maven, JUnit, Cucumber, RestAssured, and Selenium. Our customers rely on the judgment of our QA to successfully complete the development and release of microservices (Docker, Kubernetes) to the Cloud (AWS, Azure, Google Cloud). To ensure that every QA at Estafet can meet this challenge, we have created internal QA training. With the help of a personal mentor, we create a customized training plan for new hires to improve their skills in building and designing automated testing projects using design patterns and best practices using the most popular testing libraries.

• DevOps - building solutions based on infrastructure-as-code and CI/CD processes. Key technologies we use are Kubernetes, Kafka and Elasticsearch. Primarily working in AWS environments where experience with provisioning, managing and monitoring cloud services is assumed, experience with Linux, Python, Terraform, Kafka, Elastic, CI/CD (typically Git/Jenkins), and configuration management is also required. We strive to automate processes as much as possible and ensure repeatability in the things we do.

• Data and ML - building and optimizing BigData platforms for structured and unstructured data. Using Machine Learning (ML) and Natural Language Processing (NLP) to analyze, enrich data and extract useful information. Automating the processes of training, testing and running ML models using MLOps tools such as AWS Sagemaker, Kubeflow and MLFlow.

What we believe:

We are specialists

Our team of 100 specialists and consultants work with Java, Scala, Python, QA Automation testing, DevOps & cloud. We are constantly exploring and trying out new technologies to enrich our skills. We ensure our clients have skilled consultants working on their projects. We prefer to be specialists rather than trying to do everything for everyone.

We are open and honest

We always work in partnership, share things as we see them and apply full transparency in our processes. We'd rather be honest and upfront than hide that we don't know or can't. If there is a better and more expedient way to approach a problem, we share it and show how it can be done. This leads to stronger working relationships and completing projects on time.

We are experts

Our teams are exceptional: our teams are mainly made up of senior experts with years of experience in their field. Each client has a Delivery Director who ensures timely project execution and mediates between the client and Estafet's technical team.

We are flexible

We use flexible, simple techniques that help us respond quickly to change. We typically implement Scrum with 2-week sprints to deliver value quickly in alignment with priorities and set business goals.

We stand in solidarity

We share our skills and expertise with others because we want our clients to prosper once we've completed the project. We use a variety of platforms to share information and expertise.

Additional information:

Estafet is not just a company dealing with integration projects or hiring technical specialists. Achieving digital transformation is more than outsourcing technical tasks. Implementing cloud solutions is not just about transferring or changing technologies. We believe in creating a culture and a technical ecosystem to implement new ideas, products and applications so that our partners can keep pace with the dynamics of the market. We value collaboration and successfully fit into our clients' teams by willingly sharing our knowledge and experience. We earn trust and deliver results because we are open, honest and accountable.

“By really listening to our technology needs, Estafet provided solutions that fit our unique business model. Their ongoing support and services have been instrumental to our company’s growth.”

  Tom Gilbert, Global Head of PaaS Technology

“I would like bring to your attention an important piece of work Svetlana has been carrying out over the past few months. A major improvement in our regression runtime was required, and it fell to Svetlana to improve this vital metric as part of our yearly objectives. I am happy to say Svetlana followed the guidance I provided and was able to go away and independently implement the changes, which resulted in a significant runtime reduction.”

      A testimonial from a client on Estafet’s employee

 “Shoutouts to [...] Mario Mitov (Estafet), Miroslav Vasilev (Estafet). After committing to an initially ambitious scope of work based on historical sprint performance, [...], Miro and Mario completed the committed scope and quietly went on ahead and pulled more tickets than planned into the sprint. Not only does this show brilliant hunger to get things done, it’s clear evidence that we are getting more and more familiar with our application services, moving through work more quickly and using the left over time to do more so the entire boat goes faster. Great job!”
