➡️Image Editor - software solution for editing and analyzing images The client, a global leader in the action camera industry, was wasting a significant amount of time in the image tuning process due to the image editing tools available on the market not supporting all types of images used internally. • 𝐃𝐫𝐚𝐬𝐭𝐢𝐜𝐚𝐥𝐥𝐲 𝐫𝐞𝐝𝐮𝐜𝐞𝐝 𝐭𝐡𝐞 𝐯𝐚𝐥𝐢𝐝𝐚𝐭𝐢𝐨𝐧 𝐭𝐢𝐦𝐞 𝐨𝐟 𝐭𝐡𝐞 𝐢𝐦𝐚𝐠𝐞 𝐭𝐮𝐧𝐢𝐧𝐠 𝐩𝐫𝐨𝐜𝐞𝐬𝐬 𝐛𝐲 𝟒𝐗 𝐛𝐲 𝐝𝐞𝐬𝐢𝐠𝐧𝐢𝐧𝐠 a highly-intuitive GUI application to edit multiple types of raw images. Integrated the following features: displaying a histogram, adjusting contrast and brightness, converting to RGB, applying an sRGB curve, and applying a color correction matrix.

➡️Image Validator - software solution for photo and video validation The client, a leading manufacturer of action cameras, was wasting a significant amount of time, due to the painfully slow, manual image quality validation process. • 𝐃𝐫𝐚𝐬𝐭𝐢𝐜𝐚𝐥𝐥𝐲 𝐫𝐞𝐝𝐮𝐜𝐞𝐝 𝐭𝐡𝐞 𝐯𝐚𝐥𝐢𝐝𝐚𝐭𝐢𝐨𝐧 𝐭𝐢𝐦𝐞 𝐨𝐟 𝐚 𝐧𝐞𝐰 𝐟𝐢𝐫𝐦𝐰𝐚𝐫𝐞 𝐫𝐞𝐥𝐞𝐚𝐬𝐞 𝐟𝐫𝐨𝐦 𝟑𝟎 𝐦𝐢𝐧𝐮𝐭𝐞𝐬 𝐭𝐨 𝟓 𝐬𝐞𝐜𝐨𝐧𝐝𝐬 𝐟𝐨𝐫 𝐢𝐦𝐚𝐠𝐞𝐬 𝐚𝐧𝐝 𝐭𝐨 𝟏 𝐦𝐢𝐧𝐮𝐭𝐞 𝐟𝐨𝐫 𝐯𝐢𝐝𝐞𝐨𝐬 𝐛𝐲 𝐝𝐞𝐯𝐞𝐥𝐨𝐩𝐢𝐧𝐠 multiple tools to analyze color, sharpness, noise, auto- exposure settle time, and auto-white balance settle time.

➡️SGX Analysis The client, the world’s largest manufacturer of CPUs and semiconductors, was struggling to prove the benefits of SGX, due to the lacking impact analysis. • 𝐄𝐧𝐬𝐮𝐫𝐞𝐝 𝟏𝟎𝟎% 𝐩𝐫𝐨𝐨𝐟 𝐫𝐞𝐠𝐚𝐫𝐝𝐢𝐧𝐠 𝐭𝐡𝐞 𝐬𝐦𝐚𝐥𝐥 𝐢𝐦𝐩𝐚𝐜𝐭 𝐨𝐟 𝐒𝐨𝐟𝐭𝐰𝐚𝐫𝐞 𝐆𝐮𝐚𝐫𝐝 𝐄𝐱𝐭𝐞𝐧𝐬𝐢𝐨𝐧𝐬 𝐛𝐲 𝐝𝐞𝐯𝐞𝐥𝐨𝐩𝐢𝐧𝐠 a series of micro-benchmarks to run in the SGX enclave. • 𝐀𝐧𝐚𝐥𝐲𝐳𝐞𝐝 𝐭𝐡𝐞 𝐫𝐮𝐧𝐭𝐢𝐦𝐞 𝐚𝐧𝐝 𝐦𝐞𝐦𝐨𝐫𝐲 𝐮𝐬𝐚𝐠𝐞 𝐢𝐦𝐩𝐚𝐜𝐭 by using several profilers.

➡️Instrumentation Tools for Simics Simulator The client, a global leader in the semiconductor chip manufacturer market, was losing money, due to needed expensive servers for cloud benchmark characterization. • 𝐑𝐞𝐝𝐮𝐜𝐞𝐝 𝐭𝐡𝐞 𝐢𝐧𝐟𝐫𝐚𝐬𝐭𝐫𝐮𝐜𝐭𝐮𝐫𝐞 𝐜𝐨𝐬𝐭 𝐛𝐲 𝟓𝐗 by developing multiple instrumentation tools for Simics Simulator, a software and hardware simulator, to collect data required for cloud benchmark characterization.
