Most codebases don't break overnight — they slow down, sprout edge cases, and turn shipping into guesswork. I trace the real bottlenecks, harden the foundations, and make releases boring again.

Five years of end-to-end ownership and measurable impact

  1. Senior Full-Stack Engineer @ Arbisoft

    2021 – Present

    Full-stack delivery across multiple production products — owning features from architecture through implementation, testing, and deployment while improving performance and developer workflows.

    • Cut API response times 30–70% by removing N+1 queries, reworking ORM patterns, and adding targeted DB indexes.
    • Built and scaled Celery pipelines for heavy background workloads including bulk PDF generation and scheduled reporting.
    • Built reporting and analytics systems managing 1000+ assets and surfaced operational metrics for internal teams and customers.
    • Reduced deployment time ~40% by reworking GitLab CI/CD with parallel jobs, caching, and automation.
    • Raised automated test coverage from ~10% to 60%+ with Jest, Cypress, and Vitest; enforced ESLint/Prettier/Husky quality gates.
    • Refactored frontend architecture to reduce re-renders ~30% and improve load times 20–30% via memoization, code-splitting, and cleaner state management.
    • Designed and maintained REST APIs in Django REST Framework with sensible serialization, pagination, and permission layers.
    • Owned integrations end-to-end: Stripe, SendGrid, Google Analytics, Looker BI, and real-time WebSockets.
    • Mentored engineers through code reviews and pairing; collaborated with product and design in Agile teams to ship reliably.
