“AI/software engineer with hands-on experience deploying an LLM-powered quiz generation platform for students, integrating Python services with Gemini APIs plus frontend and database components. Emphasizes production-grade reliability through observability, schema validation, async processing, and performance tuning under high concurrency, and has collaborated with product/operators (e.g., at Colombo AI) to translate real-world constraints into scalable technical solutions.”

“Unity gameplay engineer with experience shipping features for a multiplayer cricket title (RVG Cricket), including a high-impact replay system that records and replays full play sequences across all on-field entities. Also implemented Photon-based multiplayer and debugged host/client execution issues, and uses AI tools to speed up data enrichment workflows (e.g., generating/matching country ISO codes from JSON into ScriptableObjects).”

“Frontend/full-stack product builder who led SiteSnap (field documentation platform) end-to-end, including UX design, React/TypeScript architecture, and deployment. Built a complex Report Builder editor handling thousands of media assets with strong performance practices (virtualization, lazy loading) and a quality pipeline (Storybook, Playwright, Vercel previews), and shipped a smart PDF report generator under a tight demo deadline with gradual rollout.”

“Frontend engineer with experience across university and product companies (University of Montreal, Dopely, Takhfifan), owning React/TypeScript features end-to-end. Notably built a mathematically complex, multi-mode color wheel UI for designers and led quality practices at scale via conventions, RTL testing, and code reviews for junior developers, plus performance and reusability improvements in existing codebases.”

“Frontend developer who led the COC.ca (Canadian Opera Company) site end-to-end as the sole FE engineer on an AgilityCMS/.NET stack, owning master/page templates, modules, and quality. Emphasizes accessibility and responsive design, performing cross-browser/device testing with tools like JAWS, NVDA, Axe, Lighthouse, and Siteimprove; more recently built a Next.js/React/TypeScript video viewer with modal/video state management.”

“Frontend engineer (Zippia) who leads complex, form-heavy React + TypeScript workflows end-to-end, setting architecture conventions and improving performance at scale. Demonstrated strong production ownership by fixing a PDF migration issue and coordinating a recovery that regenerated PDFs for ~1700 impacted users while working closely with PM, design, QA, and a small founding team.”

“Frontend engineer in fintech who led a client onboarding platform end-to-end, building a scalable React/TypeScript architecture with Redux-driven multi-step verification workflows. Strong focus on quality at scale through UI automation/E2E testing and CI/CD (GitHub Actions + Docker), enabling faster releases (bi-weekly to daily) while staying stable despite evolving backend APIs.”

“Frontend engineer/team lead currently overseeing a 5-person team building an AI trading mobile application, using modular architecture and Jest-based testing to maintain quality as features scale. Also develops a trading/research platform in Next.js/React/TypeScript with Tailwind and Redux, including complex broker registration workflows and experience separating on-device AI components from core business logic.”

“Built and deployed a production AI-powered personalized learning platform (Django + FastAPI) featuring an LLM+RAG tutoring assistant and automated grading.
