About

Skilled in architecting microservices and end-to-end AI applications, translating complex technical challenges into business-oriented solutions. Strong collaborator and knowledge sharer, with a passion for technical brainstorming, mentoring, and driving innovation across multidisciplinary teams.

Currently

I'm a Senior AI/DS Engineer at Codetribe, where I lead AI initiatives across the organization, driving awareness, capability, and adoption through knowledge-sharing sessions and cross-functional collaboration.

Beyond that, I've had the chance to work on a diverse range of AI projects, including Voice Agents, Chatbots, and Multi-Agent Systems, with a focus on delivering practical business impact. I'm also contributing to a global leader in the media and entertainment industry by building AWS Lambda functions to automate and optimize CRM.

Previous experience

Vega IT · Data Scientist and Development Lead

Besides working on projects, provided mentorship to colleagues and actively participated in presales engagements, project estimations, and discovery phases.

Worked in Vega IT Omega on various projects as a Data Scientist, contributing to the development of MVPs and POCs. Mentored interns during their internships.

Synechron · Data Engineer

Designed and prepared data pipelines for entity resolution, including developing scoring logic and feature engineering. Retrieved data from APIs and supported ML model evaluation through data transformation and analysis.

More about my internships can be found on my LinkedIn page.

Education

After graduating with a degree in Applied Mathematics, specializing in Financial Mathematics, I successfully completed all the coursework and examinations for a Master's degree in Data Science. As part of my Master's studies, I had the opportunity to conduct my thesis research in Lisbon, in collaboration with the Department of Informatics at NOVA University Lisbon (Faculdade de Ciências).

For this work, I received an Honorary Mention from the Mathematical Institute of the Serbian Academy of Sciences and Arts in the field of computing for M.Sc. students.

Master's thesis · Semidefinite programming approach to visual storyline creation

I explored graph-based strategies for visual storytelling, modeling image transitions as a path optimization task over a BDAG.

  • Developed a custom SDP relaxation using CVXOPT to find approximate global optima under visual semantic constraints.
  • Extracted visual features from images using pretrained convolutional neural networks.
  • Calculated pairwise similarity scores to weight graph edges based on feature distances.
  • Ensured graph acyclicity while supporting bidirectional search using custom DAG traversal logic.
  • Validated transition quality through visual coherence metrics and downstream performance in visual storytelling simulations.
  • Visualized graph structures, transitions, and embeddings using Matplotlib and NetworkX.
