Clients projects

• Client had

  COTA Healthcare is a company founded by doctors, engineers, and data scientists. They combine oncology expertise with advanced technology analytics to organize and analyze cancer data to help with advanced patient care and research. The company was developing a platform called Cota Abstraction Platform (CAP) to gather and process oncological data. By the end of 2019, SoftwareMill joined the effort to support the rapid growth of the platform.

• Client needed

  One major Cota Abstraction Platform pain point was performance decline as data volume increased. The high amount of information and its presentation in the user interface may lead to bottlenecks and performance issues resulting in a poor user experience. Also, it was crucial to allow end users to export, analyze, and conveniently create reports. Another platform's challenge was proper system monitoring implementation.

• We did

  We participated in the design of the architecture of the CAP system. Our goal was the seamless introduction of new features while retaining the stability and reliability of the project. The initial part of the platform that we started developing was tightly coupled to other parts of the system so we extracted it into a dedicated Scala service with its own CI/CD pipeline. We created a denormalized model optimized just for queries that was derived from original data. We also addressed the need for durable data exports and reporting. Our paramount goal was to migrate CAP to use the newest available versions of language, libraries, and frameworks.

• Outcome

  Throughout 2019 the client acknowledged how impressed they were with our commitment, execution, and expertise, so in 2020 they decided to form a self-organized team made up exclusively of our engineers. The team was operating in the agile methodology with the client’s Product Owner and Scrum Master. The team acquired responsibility for some modules that were part of the platform. It also helped outside of their scope on demand. Read more about the project in this case study.

• Client had

  A messaging gateway service that was running on a local data center and was no longer efficient.

• Client needed

  The client needed to adopt the existing on-premise infrastructure to the cloud environment in order to provide a highly available, scalable and resilient system.

• We did

  Using Kubernetes, Helm, and Terraform on AWS, SoftwareMill developers were able to quickly test and validate different migration strategies with the aim of minimizing service disruptions down to minutes, not hours or days. The development team has successfully migrated the on-premise system to the AWS cloud and also improved availability, resilience, and scalability of the system. The complexity of the deployment process and the level of software maintenance effort were also reduced.

• Outcome

  The Intelli Messaging system has increased overall traffic handling capacity and made improvements to critical components and processes along the way. The complete migration from the on-premises data center to AWS cloud solutions took about a year to finish. Read more about the project in this case study: “Migrating SMS Gateway service to the AWS Cloud”.

• Client had

  An established, well-known trading system based on Scala and Akka. The system was close to its limits of traffic handling.

• Client needed

  A new reactive platform, written from scratch with scalability and resilience as primary goals. The new platform needed to be able to take over traffic from the current one with minimum downtime.

• We did

  Our team designed and implemented a set of services that communicate asynchronously thanks to extended use of Event Sourcing approach. This allows flexible recovery, auditing, and service integration. With Akka Cluster, Akka Persistence, Cassandra and Kafka we provide scalability on many levels. We also prepared advanced performance tests to ensure that the solution can handle large growth of transaction volume with time. Additionally, we built a rich monitoring setup around the new system, using Prometheus, Grafana, and Graylog.

• Outcome

  A performant reactive system allowing fast trading, and processing growing traffic with very high resilience in case of failures. Read more about the project in this case study.

• Client had

  Flexys is an enterprise collections software that helps companies with debt resolution. It consists of a range of modules that enable creditors to engage with their customers on their preferred channel at the right time, using targeted language. On the technical side, Flexys had an MVP of the product that proved the business model is successful. Client needed an experienced team extension that would help not only with the product kick-off but also the team setup.

• Client needed

  Our main task was to help Flexys with the technical side of the project while they built the team from the ground-up. We functioned as part of Flexys team and provided them with deep expertise in some of the technologies they use, primarily Scala programming. At the beginning, our main task was reviewing the code base and identifying opportunities for improvements. We started implementing quick fixes and came up with a plan for making major architecture improvements. Our next goal was transferring good practices to the team. We introduced in-house team to the remote work best practices, shared the code review culture and encouraged the start of a technical reading club.

• We did

  We work in a TEM (Team Extension Model) in which we augment the in-house IT team with developers that support the team with the expertise in a variety of areas including designing project architecture, developing high-quality code and mentoring. This is an ongoing development effort to build new features and functionalities for the market. We helped to develop project architecture including Akka (http, persistence), Cassandra, PostgreSQL and Angular. We also shared our best practices within backend (Scala) and front-end (Angular) technologies.

• Outcome

  We contributed both to the product’s code and team setup by sharing our best practices. The joint effort of the whole team resulted in the successful migration setup. We managed to launch the back-office part of the app, as well as brought the customer-facing part of the app to the next level. Thanks to our support Flexys has been able to deliver to their first client.

• Client had

  A custom new cryptocurrency.

• Client needed

  Online wallet for the custom currency and for Bitcoin, with transactions history and recovery tool in case the online wallet was broken.

• We did

  We built backend system for wallet for both currencies, and analyser of blockchain, for discovery of transactions transferring money to users addresses from outside. Wallet addresses are multisig, where 2 keys out of 3 are enough to sign transaction. User has 2 private keys, our customer keeps 1, so user alone can transfer money from their addresses, but our customer needs user’s cooperation to do so.

• Outcome

  Finished and tested product was delivered to customer. The customer has individual users accounts on it, as well as cryptocurrency exchange. Users are able to transfer their money, generate addresses, and see all their transactions history.

• Client had

  Legacy system with zero test coverage, tightly coupled with Microsoft infrastructure and difficult to scale/maintain. Web interface was full of bugs and not mobile friendly.

• Client needed

  High quality, scalable code and architecture that will be easy to extend and maintain. Also test coverage and infrastructure automation were two of the most important goals.

• We did

  New responsive web front-end, developed in a "mobile-first" spirit. Highly scalable API bridge that provides consistent and uniform REST API and makes further migration to Scala micro services fully transparent. We built a mobile-aware, WYSIWYG CMS and made static content management straightforward. We made deployment & infrastructure management declarative and fully automated.

• Outcome

  No vendor lock-in and help with spinning up client's own dev team. Due to high automated tests coverage (> 80%) and zero-downtime Continuous Delivery clutched with advantages of applying git-flow patterns, deployments are just a matter of formality. Project gained more confidence

• Outcome

  A platform capable of processing and analysing billions of data records in a timely manner.

• Client had

  LPP S.A. collects online customers’ data (mainly: orders stored in databases and customers’ online behaviour) from various sources. The company approached SoftwareMill to help them streamline data pipelines to be able to capture crucial metrics and derive business value in real-time.

• Client needed

  Processing data, arriving at high velocity, required battle-proven tools for stream processing and the preparation of data for a recommendation engine. Due to the nature of the online retail business client needed a system featuring self-healing, as well as load balancing. Plus monitoring of the infrastructure health and performance.

• We did

  Seven streaming applications have been delivered as well as devops scripts setting up Kubernetes and all necessary tools. As a result, our customer was able to attach custom dashboards to display the sales volume as well as feed their recommendation engine in a cost effective way without latency.

• Outcome

  A transformation of the existing batch-based process into a data streaming platform built up on mature and popular open source tools. The reports are fed in real-time via stream processing applications build up on Kafka Streams and Apache Beam allowing LPP S.A. to interact with online customers in real-time.
