With 6 years of experience in <b>Java
back-end development</b>, specializing in the <b>Spring framework</b> and
<b>Java 8</b>, I have actively contributed to healthcare information systems,
cloud-based learning platforms, and telecommunications projects. My expertise
extends to <b>microservices architecture</b>, where I successfully restructured
legacy backends into microservices, emphasizing <b>REST APIs</b> and
message-driven architecture to enhance scalability and maintainability. My
commitment to quality is evident in achieving an impressive 80% unit and
integration test coverage with tools like <b>JUnit</b>, non-functional
performance testing , memory <b>(Jprofiler)</b> and database profiling <b>
(SQLProfiler) </b>. I adhere to clean code best practices, emphasizing
backward compatibility and maximizing object-oriented design patterns for code
reusability. My diverse technology stack includes <b>EJB 2 development</b>,
<b>Spring</b>, <b>Spring Boot</b>, <b>Swagger with OpenAPI</b>, relational and
document databases (<b>SQL, MongoDB, CouchDB</b>), <b>Hibernate</b>, <b>Apache
Maven</b>, and <b>Gradle build tools</b>. I bring Agile best practices to
the table, embracing <b>CI/CD</b> for efficient development cycles.
Additionally, I have two years of experience in IoT-focused transportation
truck-connecting app development, utilizing technologies such as <b>PubNub</b>,
<b>MQTT messaging</b>, and <b>AWS EC2 instance deployment</b>. I've also
strengthened security and user-friendliness by integrating <b>Mobile Connect</b>
into core ASE products, implementing <b>OAuth2</b> and <b>JWT tokens</b>.
Furthermore, my role included finalizing upfront requirements and technical
specifications for <b>OpenStack Gateway</b>, acting as middleware to translate
between OpenStack cloud operating system APIs and native
<b>Infrastructure-as-a-Service</b>. My diverse skill set and extensive
experience make me a valuable asset for any software development team.

<div id="card-body" class="card-body">
With three years of expertise in
front-end
development including SPA using <b>Angular</b> with <b>NgRx</b> and
<b>React</b>
with <b>Redux</b> frameworks, I bring extensive experience from
various
domains,
including healthcare information systems, cloud-based learning
platforms, and
transportation systems. My skill set extends to <b>MEAN stack</b>
(Mongo
DB,
Express.js, Angular, Node.js) development and the successful
deployment
of
applications on <b>AWS EC2</b> instances. I specialize in real-time
data
communication, utilizing various messaging protocols like
<b>PUBNUB</b>
and
<b>MQTT</b> with the <b>Mosquito</b> broker.
Notably, I've developed two Android applications that facilitate
seamless
interaction between truck drivers and customers within this
ecosystem.
My
approach to SPA development revolves around creating modular and
responsive UI
components while ensuring efficient application state management
through
<b>NgRx</b> and <b>Redux</b>. I excel in managing asynchronous data
fetching,
handling events, and effectively managing side effects, all while
prioritizing
performance optimization techniques such as pagination and lazy
loading.
My commitment to code quality shines through my emphasis on reusable
component
design, reducing code duplication, and ensuring long-term
maintainability. I
consider unit testing and efficient dependency management as
fundamental
components of my development process. I possess a well-rounded skill
set
and a
proven track record of delivering SPAs that meet stringent
performance
and
usability standards.

I have a proven
track
record of
significantly improving the accuracy and efficiency of breast cancer
classification in high-resolution histology images. My approach
involves
utilizing patch-based image analysis, incorporating <b>VGG16</b>
transfer
learning, and implementing an <b>LSTM</b> sequential data processing
model while
meticulously preserving the global context for critical structures
and
features.
I excel in utilizing <b>Python</b> to implement advanced machine
learning
algorithms and techniques, and I have a talent for creating
interactive
data
applications using <b>Streamlit</b>. Additionally, I conduct my
research
and
development in <b>Google Colab</b>, showcasing my proficiency in
this
versatile
platform. My commitment to staying at the forefront of technology
and
employing
innovative methodologies to address complex challenges in the field
of
machine
learning sets me apart as a forward-thinking and impactful
professional
in this
domain.
In the realm of <b>Data Visualization</b>, I have engineered an OLAP
system
tailored for university student progress tracking, featuring
intuitive
dashboards and Excel pivot charts. This system empowers stakeholders
with the
ability to perform visual data analysis, enabling informed
decision-making.
Furthermore, I have developed an <b>Oracle Apex</b> application
designed
to
manage patient data, staff scheduling, and finances. This
comprehensive
solution
not only ensures data integrity, security, and validations but also
provides
robust data visualization capabilities. My multifaceted expertise in
both
<b>Machine Learning</b> and <b>Data Visualization</b> reflects my
dedication to
leveraging advanced technologies and data-driven insights to address
complex
challenges effectively.
