Full-Stack Engineer with 5+ years of experience building and shipping production software across React and Next.js on the frontend and Django with PostgreSQL on the backend. I take features from first idea to live deployment, and I care about the parts users never see: fast queries, clean APIs, and pipelines that hold up under real load. Over the past few years I have cut API response times by 30 to 70 percent through query tuning and indexing, built asynchronous Celery pipelines that process heavy background workloads, lifted automated test coverage from roughly 10 percent to over 60 percent, and trimmed deployment time by 40 percent by reworking CI/CD pipelines. I am comfortable owning UI architecture, REST API design, database performance, and payment and real-time integrations, and I enjoy mentoring teammates and keeping delivery steady inside Agile teams. I am looking for senior full-stack roles, including remote positions with international teams, where I can own meaningful problems end to end.

2021 – 2026 Full-stack delivery across multiple production products

• Cut API response times by 30 to 70 percent across core endpoints by removing N+1 queries, reworking ORM access patterns, and adding the right database indexes on high-traffic paths.
• Built and scaled asynchronous job processing with Celery to handle heavy background workloads, including bulk PDF generation and scheduled reporting jobs.
• Built reporting and analytics systems that manage over 1000 assets, putting clear operational metrics in front of both internal teams and customers.
• Brought deployment time down by 40 percent by reworking GitLab CI/CD pipelines with parallel jobs, layer caching, and end-to-end build automation.
• Grew automated test coverage from around 10 percent to over 60 percent with Jest, Cypress, and Vitest, and set up quality gates with ESLint, Prettier, and Husky that cut production bugs by more than 25 percent.
• Reworked frontend architecture to cut unnecessary re-renders by about 30 percent and improve page load times by 20 to 30 percent through memoization, code-splitting, and cleaner state management.
• Designed and maintained REST APIs in Django REST Framework with sensible serialization, pagination, and permission layers used by several frontend clients.
• Owned integrations end to end, including Stripe payments, SendGrid email, Google Analytics, and Looker BI dashboards across multiple products.
• Added role-based access control and tightened authentication to protect sensitive endpoints and customer data.
• Mentored two engineers, getting one comfortable with Git workflows and the other up to speed on Django, through regular code reviews and pair-programming sessions.
• Worked closely with product and design in Agile ceremonies to scope features, estimate effort, and ship reliable releases on a predictable cadence.
• Delivered features from architecture through implementation, testing, and deployment, staying responsible for quality from the first commit to production.
