PROJECTS
OClock
● Conceptualized, designed, and developed this web application to streamline the
timesheet management process, eliminating manual errors and inefficiencies
associated with traditional handwritten timesheets.
● Provided users with the ability to edit registered hours (e.g., late arrivals, early
departures, vacations) directly in the system, reducing the need for repetitive
manual corrections.
● Built using FreeSpire PDF library, .NET Core REST API for backend logic,
PostgreSQL for database management, and Entity Framework for ORM. The
frontend was developed with ReactJS and Material-UI (MUI) for a responsive
and user-friendly interface.
● Initially deployed and hosted on AWS EC2 with a custom domain configured via
Route 53, ensuring scalability and reliability. Later migrated to an on premise
Windows Server.

DITEC Ajuda
Conceptualized, designed, and developed DITEC Ajuda, a comprehensive
support service solution to provide an agile way for users to access information
via articles, contact support via chat, and receive real-time notifications about
incidents.
Developed a structured article management system that allows technical support
staff to author content, which is published only after supervisor review and
approval. This system created a centralized, shared knowledge base that serves
both end users and the technical support team, enhancing information
accessibility, consistency, and accuracy across the platform.
Enabled faster communication between end users and technical support through
integrated chat functionality, enhancing customer experience and reducing
resolution times.
Integrated with OTRS ticket management system, allowing users to create
support tickets directly within the platform.
Leveraged .NET Core 6 Web API, SignalR, Kafka, Docker, GraphQL, ReactJS,
and RSuite to create a responsive and feature-rich platform.
Designed the system using microservices architecture, with chat functionality
built as a separate service with its own dedicated database for improved
scalability and maintainability.
SISCOFFEE
● Conceptualized, designed, and developed Siscoffee, a web application designed
to manage the shared coffee bean contribution system in the office, ensuring
transparency and order in tracking who needs to buy the next coffee package.
● Replaced an outdated, chaotic manual system (which relied on scribbles and
annotations) with a streamlined, digital solution to track who contributed coffee
beans and when they were due to contribute again.
● Provided transparency and fairness by clearly displaying the current order of
contributors and preventing confusion over who should buy the next coffee
package.
● Developed using Vue.js, PostgreSQL, and Node.js, with the application initially
deployed on an on-premise Linux server. Currently, the system is being migrated
to Next.js with Supabase to enhance scalability, performance, and cloud-based
functionality.
● Worked in a multi-tenant environment, implementing security best practices to
ensure data isolation and integrity across different tenants.
Automate OTRS
● Developed an application to streamline the mass opening of tickets in OTRS, a
service management system, reducing manual effort and time while also
improving the technical support team's productivity by allowing them to focus
on more critical tasks.
● Automated ticket creation process: the user fill out a single form, and the
specified number of tickets are automatically opened, processed, and closed.
● Enhanced efficiency by automating repetitive tasks, improving workflow, and
reducing the likelihood of human error in ticket management.
● Utilized a range of technologies including AutoIT, Node.js, Selenium, Shell
scripting, HTML, and CSS to build a seamless automation solution.
