- Independently Crafted a Swift/SwiftUI-based iOS tool to detect code theft by comparing Mach-O symbol tables of two iOS apps, without source code access.- Wrote clear and modular, maintainable code by following the ‘SwiftStyle Guide’ and SOLID principles.- Enhanced the app's robustness by incorporating modern Swift error management and unit testing through the XCTest framework.- I implemented abstraction of network requests utilizing the Combine framework to facilitate event-driven programming and data stream management while simultaneously employing Swift's async/await to efficiently handle individual asynchronous tasks.- I facilitated technical recruitment by assessing candidates with pivotal Swift programming questions.

For a comprehensive visual insight into my career as an inventor, I invite you to view the two videos provided below.I have innovated an advanced e-bike model that offers users an affordable, car-independent lifestyle. My role extends beyond design; I have provided education and instruction to others in constructing this enhanced e-bike both remotely and on-site. This model boasts several key attributes that set it apart. It offers a significantly extended range, tripling the distance compared to standard e-bikes. It achieves this by incorporating a custom-designed battery pack with unique circuitry and charger, which not only enhances the e-bike's lifespan but also extends its range. Additionally, the user-friendly design prioritizes practicality and ease of repair, making it a durable and accessible choice for riders.Furthermore, my innovation introduces new travel dimensions with this electric bicycle, incorporating an electrically inflatable air mattress for comfort, a portable reverse osmosis water filtration system to ensure clean and safe drinking water during travel, and an expanded trunk size that revolutionizes camping e-bike trips by effortlessly carrying all essential gear and equipment.Furthermore, I have explored innovative electromagnetic mechanisms to advance energy storage capabilities.My passion lies in pioneering innovative designs in sustainable transportation and travel, aiming to revolutionize the way we move and explore.I also have developed a novel laundry appliance, 'The Vortex Clothes Dryer,' which exhibits the potential for enhanced energy efficiency. This advancement is pivotal in the context of the considerable annual spending on electricity for drying clothes, amounting to $11 billion in the United States. The dryer operates by creating a dynamic vortex of dry air, representing an innovative leap in the realm of energy-efficient domestic appliances.

- Completed ACIS Tour Manager training in January 2023, acquiring essential skills in tour logistics, emergency response, and cultural sensitivity to effectively lead educational tours.- Spearheaded the execution of educational tours for high school students, ensuring enriching and culturally immersive experiences.- Facilitated cultural exchanges and educational workshops, enhancing students' global awareness and appreciation for diverse cultures.- Fostered a safe and inclusive environment for all participants, prioritizing their well-being and ensuring compliance with all safety guidelines and regulations.- Handled emergency situations and unexpected changes efficiently, demonstrating strong problem-solving skills and a calm demeanor under pressure.- Continuously evaluated tour components for quality and educational value, providing feedback to ACIS for ongoing improvement and innovation in tour offerings.

- Refactored severals app from MVC to MVVM design architectural pattern to facilitate white box testing.- Implemented dynamic constraint(auto layout) from photoshop specifications in XIB/Storyboard.- Implemented key features across multiple apps, including math equation solving, image processing (with OpenCV), and VOIP recording, using Objective-C++ and Swift.- Enhanced application stability by resolving 207 bugs, integrating essential runtime validations, and substantially increasing code coverage.

I successfully achieved an 80-100-fold increase in return on investment over a period of six years. This notable growth was primarily driven by my expertise in algorithmic trading and leveraging cryptocurrency market data through web scraping techniques.Created a Python program to generate profits from the most volatile cryptocurrencies with algorithmic trading, by matching the Fibonacci Retracement Levels against the order book to provide transaction triggers at any given moment with yfinance and ccxt python library.I also developed a live predictive model that scrutinizes the top 50 influential cryptocurrency websites to ascertain the popularity trends of various digital tokens with the 'requests', 'sqlite3' & 'pandas' libraries.The user can then provide an accepted volatility level which the program maps against the Relative Strength Index and my live predictive model, to make risk-aware exchanges.I've also developed secure protocols for interaction between the trigger and transactional components of the system with the rpyc python library. I implemented safety features with Transaction Limits/Condition Checking/Timeouts/Fail-Safe Mechanisms to detect and avoid untenable financial positions, even during system anomalies, maintaining both asset protection and operational efficiency. 99.9% uptime was achieved with 99% unit testing code coverage and integration testing with the unittest library.

I spearheaded the development of both client and server components, rapidly achieving proficiency in Android development from scratch after just a few weeks of training. I developed an Android app using Kotlin and implemented the server-side in Golang, with MongoDB as the database. I have transitioned all user interface components from Relative Layout to Constraint Layout, ensuring optimal compatibility across a diverse range of screen sizes.I have conceptualized and implemented an application focused on ensuring the provision of top-quality water, coupled with an integral strategy to eliminate plastic waste. This was achieved by offering essential information about water dispenser machines in Thailand, including:- Providing water quality data with Total Dissolved Solids (TDS) values- Mapping water dispensers- User feedback and comments
