About Me

I'm an Informatics Engineering student with a passion for transforming complex business challenges into elegant, data driven software solutions. My journey in technology has been defined by a dual focus: building a strong academic foundation in areas like Machine Learning and Database Architecture, while simultaneously applying these skills to solve real-world problems. My journey in the tech world has been marked by a lot of struggle, innovation, collaboration, and a commitment to be excellence.

Portfolio

In my freelance work, I've developed AI-powered tools from the ground up, such as an intelligent Route Optimization Engine and a Discount & Margin Simulator. In these projects, I handled the full development lifecycle from designing a secure RESTful API in Python to building a responsive JavaScript frontend. A key part of my work involved sophisticated prompt engineering to leverage Google's Gemini API, turning it into a powerful engine for logistical analysis and financial forecasting. This experience reflects my dedication to delivering solutions that not only push technological boundaries but also prioritize user trust and integrity.

Through my academic projects, like building a predictive model with Decision Trees or developing a mobile data management app using Flutter and SQLite, I have honed my ability to work with data, manage complex requirements, and collaborate effectively in a team. I am driven by the process of understanding a core business problem and architecting a technical solution that is not only functional but also efficient and scalable. I am now eager to bring my skills in software development, AI integration, and problem solving to a professional environment where I can contribute to creating impactful technology.

Portfolio

As part of my database course, my team and I developed the "Flexofast" application to solve the challenge of fragmented information management within the company. The goal was to improve efficiency and simplify tracking. On the technical side, we used the Drift ORM Flutter package to manage a local SQLite database.

For my first freelance consulting project, I built a full stack prototype, intelligent routing engine to help a client fix delivery inefficiencies.] The system uses a responsive UI (HTML/CSS/JS) that calls a Python REST API. This API securely proxies the Google Gemini API to solve the Vehicle Routing Problem (VRP). The API first design makes it ready to integrate directly with the client's existing ERP.

I created a City & Zone Discount Simulator prototype to help a client set smarter, more profitable discount strategies. The responsive UI, built with HTML/CSS/JS (ES6+), allows users to test different scenarios. It works by making asynchronous fetch() calls to the Google Gemini API. I used prompt engineering to instruct the AI to act as a business analyst, feeding it dummy data and getting back a strategic analysis in a structured HTML format. This project turned a complex business analysis problem into an automated, interactive tool for data-driven decisions.

I led the development of a predictive model for an AI course to classify car feasibility using a real-world dataset. My focus was on building a Decision Tree classifier from start to finish. I preprocessed the data with Pandas, converting categorical features to numerical values using Scikit-learn's OrdinalEncoder. To handle class imbalance, I applied SMOTE on the training set. I then trained and fine tuned the classifier by adjusting key hyperparameters like max_depth to prevent overfitting. Finally, I validated the model's predictive power on a test set, analyzing its performance with a classification report and a confusion matrix.
