Software Engineer (Part-Time) at Quantum Tunnel Design
June 1, 2025 - September 10, 2025Contributed to the development of quantum simulation tools in an Agile Scrum environment, using Jira for project tracking and improving sprint velocity by 15%. Engineered a scalable AI-driven quantum simulation platform enabling real-time execution of algorithms on actual quantum devices and reducing simulation runtime by 30%. Automated quantum code generation using Python, OpenAI API, and Qiskit, cutting manual coding time by 60% and boosting research team productivity. Developed and deployed a full-stack web app with React, Next.js, and PostgreSQL to manage quantum experiments, enabling 100+ real-time executions weekly via Jupyter Kernel Gateway. Implemented robust workflow pipelines, increasing reliability and reproducibility of quantum computations to over 95% test success rate.
Intern Software Engineer at WSO2 Lanka (Pvt) Ltd
October 1, 2024 - September 10, 2025Developed a centralized AI evaluation framework with customized metrics, validating LLM outputs with 90%+ precision, directly improving Asgardeo’s AI features. Improved output accuracy by 25% and reduced hallucinations through actionable developer feedback. Automated evaluation with GitHub Actions in CI/CD pipelines on UNIX environments, reducing QA time by 30% and improving reliability for 50+ developers. Collaborated with the AI team to optimize validation processes, reducing model errors by 25% and strengthening robustness across AI-integrated services. Delivered reliable software components with senior engineers, achieving 100% on-time delivery and enhancing code quality through unit testing. Applied SDLC best practices, improving code coverage by 20% during iterative refinement cycles.
