Final-year Computer Engineering student and full-stack developer working across React, TypeScript, .NET and SQL — from polished interfaces to APIs and production debugging.
Contributed to a multi-application sports platform with React 19, TypeScript and ASP.NET Core. My work covered registration, role-aware chat, attendance reporting and data consistency. The platform has since closed; the case study documents my contributions.
A bibliographic analytics platform combining Python ETL, Flask REST APIs and MySQL with a JavaScript/D3.js dashboard. Integrates DBLP publications and venue rankings for search, author profiles and interactive comparisons.
A Java 17 and Spring Boot application for traineeship management, with authentication, role-based workflows, placement matching, logbooks and evaluations. Controller and service behavior is covered with JUnit 5 and Mockito.
Text classification for SemEval-2025 Task 9: predicting food hazard and product categories from recall reports. Compared word/character TF-IDF and LinearSVC pipelines with a DistilBERT baseline; the final reported Subtask 1 score was 0.78003.
A multi-stage compiler for a Greek-language programming language. Python lexical and recursive-descent analysis lead to intermediate quadruples, symbol tables and RISC-V assembly, with support for functions, procedures and parameter passing.
Source-level systems work around Kiwi and the Linux Kernel Library (LKL), including implementation work and technical reports.
R-tree implementation with STR bulk loading and window range, distance range and k-nearest-neighbour queries.
Database optimization algorithms covering selectivity histograms, semi/anti joins, hash and sort-merge joins, pipelining and three-way joins.
Developed and maintained features across a multi-application React 19 / TypeScript and ASP.NET Core platform. Worked across UI, APIs and SQL data, with Git-based reviews and testing supporting delivery.
Read the work story ↗Improved registration and course navigation with responsive, consistent user flows.
Worked on chat permissions and recipient selection across user roles.
Resolved attendance, evaluation and payment presentation issues across product screens.
Investigated production issues with browser tools, REST APIs, SQL and Azure Data Studio.
I like understanding how the whole product works — interface, API, data and the messy debugging in between.
I'm Theofanis Tompolis, a final-year Computer Science & Engineering student at the University of Ioannina, completing an integrated master's degree with expected graduation in 2027. My work spans production web applications, systems projects, compiler design and data-focused challenges.
I care about clean interfaces, maintainable code and getting features over the line instead of stopping at the demo stage.
