One of my main accomplishments during my time at this company was the
successful implementation of a project for PUMA, which involved the scanning of
QR codes from shoe boxes and subsequent verification of the codes. To accomplish
this, I utilized a technology stack that included PostgreSQL and Spring Boot. I added
full audit capabilities for all actions related to the scanning process, including user,
date, and verification status, with the data being stored in the database layer. This
achievement not only allowed for the accurate and efficient tracking of scanned
codes but also provided valuable insights for future improvements and updates to
the system.
I am currently engaged in a microservice-oriented project, where my responsibilities
encompass developing novel features while providing support for extant
functionalities. The technical stack utilized on this project is comprised of
Spring Boot, Cucumber, AWS, JUnit, Mockito, Docker, and Apache Camel, with
communication between microservices being facilitated through the utilization of
SQS SNS. Amongst the many feats accomplished thus far, one of the services
was equipped with an integration module, designed to extract current currency
rates from a third-party provider on a daily basis. The updated currency data was
subsequently stored in AWS S3, and an additional caching layer was added to limit
S3 requests. Additionally, I established a system for notifying other services of
updated data within the S3 store via the utilization of SNS. A notable achievement
on the project was the successful integration of TestContainers, which provided a
more efficient and streamlined means of adding integration tests to the project.

I worked with the Hybris stack and was responsible for implementing services and
DAO layers. I also implemented REST APIs and added a separate SOLR instance
for tracking prices. Additionally, I gained experience working with Hybris-specific
models, such as populators and facades, and had exposure to the backoffice and
hac.

Developed converters to transform Fast Healthcare Interoperability Resources
(FHIR) data into a format compatible with our database schema, enabling seamless
integration of medical data from external sources into our platform. Additionally,
I played a role in designing the database structure to store FHIR-compatible data,
ensuring that we adhered to the necessary healthcare standards and regulations.

As a web application developer for a healthcare project, I was responsible for
implementing services and DAO layers as well as integrating with AWS S3 to
securely share generated PDF reports using signed URLs. I also implemented
gRPC for efficient communication between services and developed a job
scheduler/executor for task automation. Additionally, I implemented a PDF
generator to produce customized reports from provided data and samples.

I implemented an application for constructing information on labels for clothes using
a technology stack that includes Spring Boot, PostgreSQL, JavaScript, and jQuery. I
added various components that enable bulk editing of different label components,
as well as customization of labels.
