What I'm looking for

I’m looking for a role where I can build scalable backend systems and contribute to ML/AI evaluation. I want collaborative Agile teams, strong quality practices, and opportunities to solve complex technical challenges with reliable deployments.

I’m a results-oriented Software Engineer with experience across backend engineering, machine learning, and AI evaluation. I design scalable applications and build data-driven solutions using modern software engineering practices.

In my recent roles, I’ve delivered secure, reliable backend components by developing RESTful APIs, improving scalability and performance, and supporting Agile workflows like sprint planning and code reviews. I also automate testing and debugging to strengthen software quality.

I bring hands-on experience with machine learning pipelines, data preprocessing, feature engineering, and evaluating model performance. I’ve worked on AI quality assurance by evaluating AI-generated outputs for accuracy, consistency, and overall reliability, and by identifying edge cases.

I’m especially motivated by solving complex technical challenges—whether that’s implementing event-driven distributed systems, building forecasting and anomaly detection models, or creating production-ready cloud deployments. I value dependable, maintainable systems and clear documentation as part of engineering excellence.
