Your backend architecture shouldn't be the bottleneck that stops your business from scaling. Clients typically bring me in when their existing platform is struggling under high transaction volumes, when complex third-party API integrations are failing, or when they need a seasoned developer to take full ownership of a product from the database layer up to the UI. I don't just take tickets and write code in a vacuum; I figure out exactly how your business logic works, catch the edge cases, and ship hardened, production-ready features. My core expertise is building scalable, secure backend systems and APIs using .NET Core and Node.js, backed by PostgreSQL and Redis. Whether I am architecting a clean layered structure for a new SaaS product, integrating complex payment gateways, or managing bare-metal Linux server environments and Proxmox setups, I handle the technical heavy lifting so you don't have to micromanage the process. On the frontend, I deliver responsive, high-performance web applications using modern React and Angular. I rely on concrete data and direct SQL queries rather than abstract assumptions to solve complex technical problems. Recently, I developed the database migration and audit logic for a large-scale educational management system, and I regularly configure fail2ban security rules, SSL certificates, and Nginx reverse proxies for institutional web platforms. I treat your infrastructure with the same rigor, utilizing modern workflows to identify and resolve vulnerabilities before they hit production. If you have a product and need a developer who can jump straight into the codebase, fix deep performance issues, and drive development end-to-end, let's talk about your roadmap.
