Problem
Large file downloads benefit from parallel segment fetching rather than a single sequential stream.
Context
Personal systems-programming project.
Role & Ownership
Built the threading, HTTP range-request logic, and Tkinter GUI.
SCOPE CLARIFICATION
This is a focused technical implementation project. It demonstrates concurrency, parallel task orchestration via HTTP range requests, progress tracking, and file merging — framed as a systems-programming exercise rather than a production download service.SYSTEM DESIGN
Architecture
A Tkinter GUI drives a threaded downloader that issues HTTP range requests to fetch file segments in parallel, tracks progress per segment, and merges completed segments into the final file.
SCOPE NOTE
Desktop utility, not a hosted service.
KEY CAPABILITIES
What it does
Segmented/parallel download via HTTP range requests
Progress tracking UI
File merging after segment completion
TECHNICAL STACK
Technologies used
CAPABILITY PROOF
What this proves
Lower-level systems programming comfort (threading, HTTP internals) beyond typical CRUD web work.
