Project history
TEST ENVIRONMENT MANAGEMENT
The client, active in the UK banking industry, was wasting a lot of time on repetitive and error-prone
testing work due to an environment holding an unnecessary and excessive amount of poorly managed
data.
Eliminated excessive data volumes incurring costs of around £70K per year by implementing
complex business use cases aiming to identify and pre-condition data to suit testing scenarios.
Skills: .NET 6, T-SQL, Azure ServiceBus, Storage, CosmosDB, TDD, React, NextJS

ENDOSUITE SYSTEM DIGITALIZATION
The client, the German leader in launching and scaling digital ventures, needed to build the next
generation of endosuite applications due to low productivity among medical teams and decreasing
health outcomes.
Reduced cognitive load of doctors and decreased overall time spent on reporting writing from 3
hours to less than 5 minutes by implementing a seamless integration of intra-procedural findings,
images, annotations and recommendations into the overall reporting.
Increased team proficiency and efficiency by 2x by adopting coding guidelines and reduced code
coupling by shifting from Layered Architecture to a Vertical Slice one, leading to an easier
implementation of change requests.
Skills: .NET 6, Azure, HL7 Fhir, Keycloak, Terraform, Dicom, Containers

The client, the UK market leader in digital cheque processing, was dealing with a decline in cheque usage
at a rate of approximately 20% per annum.
Effectivelly reduced system operating costs by migrating from physical Data Centers to a Cloud-
Based platform and supporting the transition from a fxed-cost to a variable-cost model through a
well-designed serverless solution.
Achieved an 80-85% test coverage by separating the domain layer (accountable for business logic)
from the application services layer (for communication with external systems), enabling sustainable
growth of the project and providing maximum value with minimum maintenance costs.
Skills: .NET 5, Serverless Event-Driven Architecture, Bicep, Azure: Function Apps, Storage, Cosmos DB, Service Bus, TDD, BDD

END-TO-END YOUTUBE PLAYLIST AUTOMATION
The client, a start-up company providing software solutions for the music industry, received many
complaints from its customers because of a missing automated system for transferring their audio files
to YouTube personal playlists easily and interactively.
Tripled user experience by making use of SPA on the front-end and integrating SignalR on the highimpact
pages for real-time web functionalities. Enhanced the UI by integrating highly useful widgets
like grids, graphs & charts, schedulers, file explorer, media player, and many more.
Eliminated the probability of duplicated songs by integrating an audio fingerprinting module by
which the system can recognize already existing songs from a user collection with 100% success
rate.
Skills: ASP.NET Core, SPA, Azure, EF Core, Google API, Hangfire, OData, RabbitMQ, SendGrid, NodeJS,
ReactJS, Elasticsearch, WPF, Wix Toolset, Signal Processing, Containers
