Project details

Looking to build or improve a PostgreSQL database that can handle large volumes of data with high performance and integrity? I specialize in designing scalable, relational data models and optimizing PostgreSQL for mission-critical applications—government systems, survey platforms, education records, and more.

With over 10 years of experience working on national-scale projects, I deliver not just a schema, but a solid foundation: normalized tables, foreign keys, advanced indexing, materialized views, and triggers—everything documented and production-ready.

Whether you’re starting from scratch or need to tune an existing system, I can help you eliminate bottlenecks, prepare for high concurrency, and scale with confidence. Every package is tailored to your project size, use case, and growth expectations.

Let’s build a PostgreSQL database that’s not only functional—but fast, secure, and future-proof.

I’m a full-stack developer and systems architect with 10+ years of experience building scalable, secure, and high-performance web and mobile applications. I specialize in modern technologies such as Angular, Node.js, GraphQL, PostgreSQL, MongoDB, Ionic, Express.js, and DevExpress, and have implemented solutions in both AWS and Google Cloud Platform (GCP) environments.

My background includes leading digital transformation projects for federal government institutions, political parties, financial institutions, and education systems. I’ve developed and maintained large-scale platforms, administrative dashboards, mobile apps, and real-time data systems aligned with strict compliance and high-availability requirements.

What I can help you with:
• Frontend & backend web applications (Angular + Node.js + GraphQL)
• Cross-platform mobile apps (Ionic for Android & iOS)
• Database modeling & migration (PostgreSQL, MySQL, Oracle, MongoDB)
• API development (REST & GraphQL with authentication and security best practices)
• Cloud deployment & architecture on GCP and AWS
• Agile project execution and technical documentation

I work with a strong focus on:
• Clean and maintainable code
• Transparent communication and timely delivery
• Understanding your business goals to provide real value

If you’re looking for a skilled professional who can bring your idea to life or enhance an existing system, let’s connect. I’m available up to 32 hours per week and open to both fixed-price and hourly projects.

Let’s build something great together.
