Nikhil Vashisht — Quality Assurance Engineer & Python Developer

01 // PHILOSOPHY & BACKGROUND

Physical understanding precedes every line of code.

Real manufacturing environments demand zero cloud dependencies, instant UI responsiveness, and foolproof audit trails.

MANUFACTURING QA EXECUTIVE

Grounded in the plant reality.

At NHK Spring India Ltd., I actively manage Statistical Process Control (SPC), capability studies ($C_{pk}, C_{pu}, C_{pl}$), inspection test certificates, ISO compliance, and 8D root-cause investigations. I understand how operators work and where mistakes occur.

SOFTWARE & AUTOMATION DEVELOPER

Fluent in modern desktop engineering.

Holding a Bachelor of Computer Applications (BCA), I design full-scale offline desktop applications, multithreaded Python GUI tools (PySide6/Tkinter), SQLite databases, and Zebra ZPL barcode generation pipelines that automate hours of manual reconciliation in seconds.

03 // FEATURED APPLICATIONS

Enterprise Software & Live Telemetry.

Real-world operational systems designed to enforce 100% data integrity and fail-safe shop-floor execution.

FLAGSHIP ENTERPRISE SYSTEM

NHK_RIMS — Raw Material Inventory & Traceability System

A custom, high-reliability desktop application engineered for automotive manufacturing. Tracks the complete lifecycle of steel raw materials: from supplier invoice receipt and physical bundle weighing, to FIFO age-priority lot allocation, production consumption, and immutable audit adjustments.

                  100% Offline Resilience: Zero dependency on external networks; instant SQLite atomic transactions.
                

                  Physical FIFO Engine: Algorithmic lot recommendation based on age and heat verification.
                

                  Audit Ledger: All adjustments require operator authentication, reason logging, and reversal tracking.
