Senior BSc Computer Science student in Univeristy of Wisconsin-Madison with experience in UI/UX design and software integration. I am very enthusiastic about learning to utilize new technologies to build projects that can solve real-world problems.

## Work Experience
### Software Engineer 1 @ LinkSquares
Jan 2025 – Present | Boston, MA
Implemented OAuth 2.0 authentication support for Ramp within an authentication micro service using a Rails service adapter pattern with custom access token extraction, refresh token logic, and REST endpoints for frontend authentication, status retrieval, and token revocation.

Constructed a Ramp webhook service layer utilizing a service class pattern to wrap API endpoints with preemptive access token refresh, orchestrating the full webhook lifecycle including challenge token verification and multiple webhook event support, unblocking 12 downstream integration projects.

Architected technical design of white labelling feature that leveraged the AWS API by integrating the SDK into existing controllers to apply email template customizations and generate DNS records to enable custom sending domains with DMARC compliance. The feature maintained critical app support and created 39 upsell opportunities.

### Associate Software Engineer @ LinkSquares
Jan 2023 – Jan 2025 | Boston, MA
Maximized product stickiness with custom integrations created on a workflow automation platform that utilizes the public API adhering to RESTful standard. Additionally, designed BI solutions that operate on Looker and are powered by Snowflake as the data warehouse which influenced millions of ARR and churn prevented

Expanded integration versatility by constructing a data streaming mechanism with Sidekiq and services classes to manage imported 3rd-party data that ensures data parity across platforms which led to a 4.4% increase in SOW conversion rates.

### API Engineer Intern @ DailyPay, Inc.
Jan 2022 – Jan 2022 | New York, NY
Enhanced observability and production readiness by profiling API endpoints using Datadog to generate latency distribution graphs and investigating latency issues using dashboards; documented findings in a RFC to provide a solution roadmap for a team of 10 engineers

Hasten investigation time by 10x by building monitors and alerts for requests going through AWS API gateway that trigger notifications in Slack and PagerDuty using Datadog to provide engineers insight into exceptional requests

Improved developer experience by designing a visibility feature using Rails that enhances abstraction which saves 200% of developer time; also updated swagger documentation using the OpenAPI spec

Optimized code reusability for controllers by leveraging Rails concerns design pattern to create a controller action that contains logging designs, along with corresponding logger tests in Minitest

### Software Integration Intern @ Morgridge Institute for Research
Jan 2021 – Jan 2022 | Madison, Wisconsin, United States
Enhanced continuous integration process by implementing a Dockerfile that uses build arguments as a GitHub Action to optimize Docker image build time when building all image configurations, saving 90% of deployment release time

Implemented improvements to performance bottlenecks in container build/push workflow by increasing key range and utilizing a temporary cache file resulting in a 20% performance increase

Developed a certificate name validation script in Python to identify invalid names and incorporated the script into a continuous integration pipeline using GitHub Actions

Remodeled Bash testing script to utilize internal integration testing package to improve test reliability

### Software Engineer Intern @ Superceed Universe Sdn. Bhd.
Jan 2020 – Jan 2021 | Kuala Lumpur, Federal Territory of Kuala Lumpur, Malaysia
Overhauled UI of AI powered chatbot flow software by utilizing ReactDOM and the component lifecycle with React.js and Typescript to improve UI consistency and reduce UI complexity

Researched on Slack and Telegram APIs to write JavaScript software that utilizes API calls and webhooks to
demonstrate usage and limitations, which provides an implementation strategy for a team of 5 engineers

Communicated with engineers to address UI issues and presented API integration research to the engineering team

### Grainger Catering @ Wisconsin Union
Jan 2020 – Jan 2020 | Madison, Wisconsin, United States
Worked with organizers and other caterers to set up and facilitate events held for customers.
