Full Stack Developer

Netpeak | (3+ years)

Progressed from a process automation specialist (Python) to a Full Stack Developer, independently designing and deploying the architecture of complex web applications.

Platform Design & Development (Laravel / Vue / Inertia):

  • Designed application architectures from scratch: DB design, process mapping, business logic, and functional requirements.
  • Ensured technical SEO and configured SSR for SPAs, guaranteeing 100% page indexation by search engines.
  • Optimized performance: configured database replication, utilized Redis for caching heavy queries and queue processing.
  • Integrated payment gateways (Stripe via Cashier) and authentication systems (Socialite).
  • DevOps tasks: containerized projects using Docker, configured Nginx, and deployed on Linux servers (Ubuntu). Set up CI/CD pipelines via GitHub Actions for seamless production rollouts.
  • Server administration: managed DNS via Cloudflare, deployed mail servers, and implemented multi-level daily backup systems (local and external storage).

Web Development & CMS (WordPress):

  • Built a network of 100+ high-performance blogs for PBN/Linkbuilding. Deep SEO optimization provided stable organic traffic and inbound B2B requests for publications.
  • Developed corporate websites and e-commerce stores using WordPress + WooCommerce.
  • Customized CMS logic, worked with WP databases, queues, and managed hosting and domain configurations.

Automation & Data Engineering (Python / Apps Script):
