Hanik Sator
Computer science graduate and software engineer based in Chicago. I like building practical systems with clean structure, reliable backend logic, and interfaces that feel thoughtful instead of overcomplicated.

Software engineer who enjoys building practical systems, experimenting with interfaces, and creating software that feels clean, reliable, and intentional.
hanik@portfolio:~$ current_status
Currently looking for software engineering opportunities while continuing to explore backend development, systems programming, and developer-focused tools.
Software Engineering Intern
- Developed automated assessment infrastructure in Java and Python to validate data structure implementations, including AVL trees, balanced BSTs, and threaded binary trees.
- Built validation frameworks that tested student submissions against edge cases, incorrect logic paths, invalid inputs, and performance constraints.
- Designed fault-injection scenarios, unit tests, and benchmarking tools to improve reliability and reduce regressions across coding exercises.
- Collaborated in code reviews and refactored legacy components to improve maintainability, engineering quality, and overall test coverage.
Bakery Team Member
- Maintained performance standards in a fast-paced bakery department while following strict food safety and operational procedures.
- Trained and onboarded new team members on inventory systems, department workflows, and safety compliance.
- Managed inventory rotation, replenishment, and product presentation to maintain accuracy, reduce waste, and support daily operations.
Bachelor of Science in Computer Science
- Graduated with a 4.0 GPA.
- Earned Dean's List recognition for seven consecutive quarters (2023–2025).
- Completed coursework in data structures, operating systems, distributed systems, software testing, compiler design, and database systems.

~/projects/rc_car
Remote-Controlled Car
Raspberry Pi based vehicle using Python control logic, GPIOZero, motors, LEDs, sensors, and real-time movement commands.
Embedded hardware project
Motor control, GPIO, hardware feedback
Directional control, LEDs, buzzer response
Iterative hardware/software debugging
Highlights
- Integrated motors, sensors, LEDs, and buzzer feedback through Raspberry Pi GPIO.
- Developed Python control logic for speed, direction, and movement commands.

~/projects/chicago_transit
Chicago Transit Dashboard
Real-time CTA dashboard for tracking active trains, station arrivals, line activity, and Chicago weather across the city's rail system.
Real-time transit dashboard
APIs, live data, geographic visualization
Train tracking, station arrivals, line filtering
Cloudflare Pages and Functions
Highlights
- Visualized live train positions across all eight CTA rail lines using geographic route and station data.
- Added station arrival predictions, automatic data refreshes, line filtering, and system-wide train status.
- Reconstructed shared Red, Brown, and Purple Line corridors to reduce overlapping route geometry.
- Routed CTA requests through Cloudflare Functions so the API key remains outside the browser.
