Technical Lead - Senior Java Developer
décembre 2020 - Aujourd'hui (5 ans et 6 mois)
Bruxelles, Belgique
As a technical lead within the E-Procurement team, Taha contributed to
building a new platform from scratch. Working based on business requirements
and within a Scrum framework, he played a key role in creating a set of
dockerized Quarkus REST APIs deployed on an OpenShift cluster.

He designed API contracts using OpenAPI, modeled ERD diagrams, and sucured apis using SSO authentication through Keycloak. Additionally, he developed efficient integration tests by leveraging Testcontainers for backend services and Cypress for end-to-end testing.

Taha conducted refinement sessions where software design and
technical solutions were discussed. He mentored junior colleagues, provided
guidance on challenging tasks, performed code reviews and ensured code maintainability.

On the front-end, he utilized Vue.js and its various modules, including Vue
Router, Vuetify, and Axios, to develop reusable components that enhanced
scalability and maintainability.

Taha also designed and implemented solutions to parse complex Excel files using
Apache POI, handle large binary uploads with MinIO, and send multilingual
emails using the Qute templating engine. For GDPR requirements, he implemented a custom Keycloak configuration for on-the-fly encryption and decryption of sensitive data.

Additionally, Taha led the migration of data from the old platform to the new
one, transitioning from MySQL to PostgreSQL, while ensuring data integrity and
seamless integration throughout the process. He also addressed OWASP vulnerabilities to strengthen application security.

Isabel Group
Senior Software Engineer
septembre 2019 - novembre 2020 (1 an et 2 mois)
Taha was part of the Multibanking department within Isabel Group, where he
contributed to developing a payments solution platform called Seven.

As a member of a Scrum team, Taha participated in refining user stories by
performing technical analysis and design. He implemented new features in several REST and GraphQL APIs, using both contract-first (JSON:API & OpenAPI) and code-first approaches.

Taha addressed technical debt in multiple microservices by applying coding best
practices and design patterns. He also migrated services to JDK 11 and began
planning the migration to JDK 15. Additionally, he implemented monitoring features on OpenShift using Prometheus and Grafana.

Taha played a key role in integrating Seven with Zoomit, a solution leveraging
mutual TLS authentication. He coordinated efforts between the two teams and
managed communication with the networking/infra team regarding PKI.

In terms of testing strategy, Taha implemented contract testing using Pact to
replace brittle and expensive integration tests. He employed both BDD with
Cucumber and TDD methodologies. He also improved code coverage using tools and frameworks such as PIT, WireMock, and REST Assured.

Tools/technologies:

Java 8/11, Spring 5, Spring Boot, Docker, OpenShift, Prometheus/Grafana,
Intellij, Rest, GraphQL, Hibernate/JPA, Junit/Mockito, Pact, Cucumber,

Starting in his second year, Taha took the lead on several projects, handling
technical refinement and architectural design based on business requirements.
Taha coached junior team members, supported them in their daily tasks, and
conducted thorough code reviews.

He played a key role in breaking down complex monolithic systems into a
microservices architecture running on a private OpenShift cluster, utilizing REST
APIs and Spring Boot.

Taha also led several refactoring projects to maintain and extend existing
applications. On the front-end, he developed using GWT (Google Web Toolkit).
Additionally, he built a release pipeline using Ansible.

On occasion, Taha acted as Scrum Master, organizing Scrum ceremonies such as
planning, daily stand-ups, and retrospectives.
