Bachelor of Computer EngineeringAbout me
Full-Stack Engineer focused on building production-grade using React, Next.js, Node.js, PostgreSQL, and modern cloud tooling. I specialize in designing secure and scalable backend systems, authentication workflows, subscription-based platforms, and performant web applications.
Full-Stack Web Development
Development of production-ready web applications using React, Next.js, Node.js, PostgreSQL, and MongoDB, including SaaS platforms, e-commerce marketplaces, and AI-powered applications with end-to-end architecture.
Backend Development & REST APIs
Design and implementation of scalable REST APIs and backend services with Node.js and Express.js, covering authentication, authorization, RBAC, subscription management, and recurring payment workflows.
Cloud & DevOps
Setup and management of CI/CD pipelines and containerized deployments using Docker, GitHub Actions, Vercel, Render, Supabase, and Cloudinary for reliable and scalable production environments.
Database Design & Optimization
Design and optimization of relational and non-relational databases using PostgreSQL and MongoDB, including query optimization, schema design, and performance tuning.
Security & API Hardening
Application of OWASP Top 10 security best practices, API security testing with Burp Suite and OWASP ZAP, JWT authentication, Zod validation, rate limiting, and role-based access control.
Frontend Technologies
Building responsive and performant user interfaces with React, Next.js, TypeScript, JavaScript, TanStack Query, Redux Toolkit, and Tailwind CSS.
IT Infrastructure & Systems Administration
Over 12 years of experience managing IT infrastructure, including Windows Server environments, Active Directory, firewalls, network devices, and workstation maintenance across large organizations.
Payment Integration
Integration of Stripe Checkout and webhooks for deposits, commission payments, and purchases, including transaction locking, duplicate-link prevention, webhook dead-letter queues, and payment audit trails.
AI Service Integration
Integration of AI services such as Groq Llama, Clipdrop, and Remove.bg into production platforms with fault-tolerant processing pipelines and file-processing workflows.
