About

Professional summary

I am a self-directed Fullstack Engineer with over two years of experience building and shipping web products end to end. I work across system architecture, database design, backend APIs, user flows, and responsive interfaces for desktop and mobile.

I build modern applications with Next.js, React, TypeScript, Node.js, PostgreSQL, Supabase, and cloud deployment platforms. I am experienced in creating secure and scalable REST and GraphQL APIs, implementing authentication and authorization, and maintaining clean, reusable frontend component systems.

I have independently delivered seven production applications across task management, job-search automation, travel booking, and property investment. I enjoy translating ambiguous business requirements into reliable, user-focused software products.

My backend experience includes Node.js, Express, NestJS, FastAPI, PostgreSQL, MongoDB, MySQL, DynamoDB, and ORM tools such as Prisma, Drizzle ORM, and Sequelize. I focus on schema design, query optimization, multi-tenant systems, microservices, and scalable data workflows.

I am comfortable automating deployment pipelines with GitHub Actions and deploying applications through Vercel, Render, Docker, and AWS services. I also have experience building AI-powered user workflows, chatbot automations, third-party API integrations, and native Windows wrappers for web applications.

I communicate fluently in written and spoken English and work effectively with high autonomy. I have also led a technical operations team, improving collaboration, service delivery, and project execution reliability.
