Experience

Susquehanna International Group Bala Cynwyd, PA

Software Engineer Co-op, Team Order Routing and Quoting

September 2023 - March 2024

Engineered a high-performance C++ protocol metrics publisher implementing a zero-copy parser using std::string_view with robust handling of dangling references, lifetime management, and buffer invalidation, processing over 5.8 billion market data messages daily while maintaining nanosecond latency
Architected a scalable Python-based Kafka consumer utilizing asyncio and multiprocessing, implementing custom batching and parallel processing strategies to achieve 100K messages/second throughput, enabling processing of 500M messages in under 5 minutes
Developed a FastAPI proxy service integrating Grafana with internal trading platforms, implementing critical alerting system with customizable thresholds and automated notifications, reducing incident response time by 60%
Designed and implemented an end-to-end metrics pipeline that transforms internal DataFrame metrics to JSON format for Elasticsearch indexing, enabling Grafana-based querying and visualization, with a Python proxy service monitoring latency and volume thresholds to trigger automated Symphony chat alerts for trading anomalies
Implemented a robust GitLab CI/CD pipeline with automated testing, security scanning, and Kubernetes deployment, reducing deployment time by 70% and achieving 95% test coverage across Python and C++ codebases

Projects

Shelved

Live Github

Docker Deno Express.js JavaScript Knex.js Node.js Postgres

Developed a full-stack application to allow users to track and review multimedia content they consume
Implemented content saving, reviewing, friend management and recommendation
Designed and enforced robust authentication, input validation, rate-limiting and LRU Cache functionalities
Integrated two distinct API data sources with unique fields for consistent use across all application features

Library

Live Github

Docker Drizzle ORM TanStack Query Express.js JsonWebToken React.js SQLite Zod

Developed a fully typed full-stack application to manage books and authors data
Implemented security features for authentication and input validation to protect against XSS and CSRF attacks
Deployed on my personal VPS with other containerized projects using Docker Compose, Nginx and Caddy

Concurrent FTP UDP Server

Github

C++ UDP POSIX Threads Make

Engineered a concurrent File Transfer Protocol server using UDP with a thread pool architecture for handling multiple simultaneous client connections, implementing custom channel-based communication for efficient data distribution
Designed a robust connection management system using address-based mapping to FTPFileWriter instances, enabling parallel processing of file transfers from multiple clients
Implemented thread-safe data processing with channel-based communication between UDP layer and file writers, ensuring reliable concurrent file operations

Path Finding Visualizer

Github

SFML CMake C++

Designed an interactive grid for visualizing path finding algorithms using C++ and SFML
Integrated A* and Dijkstra's algorithm for path finding and Kruskal's algorithm for dynamic maze generation

NeoVim Configuration

Github

Ghostty Lua Neovim Bash tmux jq fzf ripgrep

Built a custom Neovim setup that matches VSCode's functionality but runs significantly faster. The config loads in under 50ms and includes everything from language servers to git integration, making it perfect for daily development work
Created a smooth terminal-based workflow combining tmux for managing multiple sessions, telescope with ripgrep for quick file searching, and tree-sitter for better syntax highlighting - all working together as a lightweight but powerful development environment
Set up language servers for all my commonly used languages that provide features like auto-completion, error checking, and code navigation, while keeping the interface clean and responsive
Added quality of life improvements like fuzzy finding, advanced search and replace, git blame and diff viewing directly in the editor, making it possible to work entirely from the terminal without compromising on features
