PROFILE

Boris Vassilev

Over five months, contributed to peshe/FMI-SDP-2024 and zed-industries/zed by building robust C++ data structures, algorithms, and tooling for both educational and production environments. Developed reusable libraries for particle systems, linked lists, expression evaluation, and graph algorithms, emphasizing memory safety through custom allocators and smart pointers. Enhanced persistence with serialization interfaces and improved onboarding via comprehensive documentation. Addressed edge-case bugs in Trie and command interpreters, and improved C++ code completion in the Zed editor by adapting to clangd JSON changes. Demonstrated expertise in C++, Rust, and algorithm design, consistently focusing on reliability, maintainability, and developer productivity across repositories.

Jan 1, 2025

January 2025 performance summary for peshe/FMI-SDP-2024: Key features delivered include a reusable Graph library with an abstract Graph interface, DFS/BFS, and a MatrixGraph implementation with an example main; Trie enhancements with memory management, destructor, and robust remove for prefix cases plus DOT visualization; and a custom hashmap with unique_ptr-based node management plus a dynamic command interpreter supporting commands with varying arguments. Addressed stability improvements and edge-case bugs in Trie deletion and memory handling. These deliverables establish foundational data-structure components, enabling faster feature work and improved debugging, with business value in reliability and reusability. Technologies demonstrated include C++, graph algorithms, memory management with smart pointers and destructors, DOT visualization, and dynamic command interpreter design.

Nov 1, 2024

Month: 2024-11 | Repository: peshe/FMI-SDP-2024 Overview: Delivered core capabilities across data structures, algorithms, and documentation to strengthen persistence, reliability, and reuse. The month focused on feature delivery for, and reliability improvements in, core components, plus documentation to boost onboarding and cross-team understanding. These efforts improve business value by enabling persistent particle systems, memory-safe linked lists, and a reusable algorithm library for expression evaluation. Key features delivered: - ParticleSystem API enhancements and serialization: added serialization/deserialization support for ParticleSystem; introduced a Point struct for 3D coordinates; Serializable interface; API improvements including size, capacity accessors, bounds-checked access, and a robust iterator. - LinkedList reliability: memory allocator and bug fixes: introduced a custom memory allocator for linked list nodes with leak detection; added a LinkedList class that uses the allocator; fixed append tail pointer and filter last-element processing to ensure correct memory cleanup. - Algorithm library refactor and data structures: refactored Shunting-yard implementation into a header for reuse; added an arithmetic expression tree with exponentiation optimizations; basic tool hierarchy for demonstrating composition. - Documentation updates for weeks 6-8: updates to Week 6 README with linked list problems; typo fixes in FMI-SDP-2024 README; Week 8 README covering tree data structures and AST creation for infix expressions. Major bugs fixed: - Fixed append tail pointer bug and filter last-element processing in LinkedList, preventing memory leaks and incorrect cleanup. - Introduced and refined a memory allocator (leak detection) to catch regressions early. - Resolved minor serialization/documentation inconsistencies across weeks 5-8. Overall impact and accomplishments: - Increased reliability and reusability of core data structures and APIs, enabling persistent particle systems and robust chain data structures. - Established a reusable algorithm library and header-first design, reducing duplication and enabling faster feature deployment. - Improved developer onboarding and cross-team collaboration through refreshed documentation and clear examples. Technologies/skills demonstrated: - C++ data structures and memory management (custom allocators, LinkedList). - Serialization/deserialization patterns and interface design (Serializable, Point type). - Algorithm design and refactoring (Shunting-yard, expression trees, exponentiation pruning). - Header-only library organization and documentation hygiene.
