Work Experience

Software Developer at DateAnnotation

09/2024 - Present

Contract

  • Trained and evaluated AI coding LLM by developing programming challenges, assessing AI-generated code for accuracy and efficiency, and providing clear, well-documented solutions in many programming languages, with 100+ completed projects

Bussiness System Analyst at McMaster University - Systems

05/2022 - 09/2023

Full-time

  • Conducted Functional, Acceptance, Performance testing on McMaster awarding platforms. Automated testing process using Selenium and command-line scripting, optimized submission response time to under 2 seconds
  • Developed a RESTful API with PDF/DOCX parsing, integrating OpenAI GPT for skill extraction and semantic matching against award criteria, enabling a 5-point candidate evaluation system that reduced review time from 50+ reviewers over two weeks to a single reviewer in just two days
  • Perform data analysis/visualization on over 37,000 Applicant data using Python and Power BI to determine business strategy, saving 5+ hour monthly query runtime utilizing dataflows and DAX queries

Software Developer Co-op at BlueWave Technology

05/2021 - 12/2021

Full-time

  • Contributed to the development of Java/Linux-based enterprise-level DNS, DHCP, and IPAM (DDI) solution, collaborating with a team of developers on two major product releases
  • Collaborated with QA engineers to develop test cases, reproduce bugs, and validate fixes, ranked as the top co-op developer for resolving the highest number of bugs during every release cycle

Projects

Lidar room scanner

  • Created an embedded 3D environment measurement device which uses an VL53L1X time of flight sensor to determine the distance around it.
  • The sensor is attached to an stepper motor which spin 360 degree within a single vertical geometric y and z plane to measure distance.
  • All controled why a MSP432E401Y microcontroller from Texas Instruments.

Flask Webpage

Created a styled multi-page website for web blogging.

  • Create forms, accept user input, and implement validation to enhance the user experience.
  • Set up a database using Flask-SQLAlchemy, interact with it in an Object-Oriented manner, and transition to Postgres for deployment.
  • Add users to the database and implement a robust authentication system using flask-bcrypt and flask-login.

Biometric Security System

Developed a AI enabled home security device.

  • Achieved 90%+ accuracy in facial recognition and pedestrian detection using Dlib, OpenCV, and MediaPipe, using pre trained facial landmark detectors for extracting key facial features and applied a support vector machine classifier to recognize faces.
  • Improved interaction speed by 70% with a voice-enabled AI assistant using SpeechRecognition, spaCy, and gTTS.
  • Engineered a high-reliability door locking system using a PySerial-controlled stepper motor on an ESP32, enclosed in a 3D-printed casing modeled with AutoCAD. Achieved 100% reliability across 1,000+ test cycles
