Work history

I build web products from backend architecture to user-facing interfaces.

I am a Full Stack developer focused on product platforms, APIs, integrations, performance and maintainable engineering.

My work sits between product requirements, backend architecture, frontend implementation and production reliability. I like systems where the code directly supports business processes, users, content, payments, integrations, analytics or internal operations.

I work across PHP, Python, JavaScript and TypeScript ecosystems: Phalcon, Laravel, Symfony, Django, Nuxt.js, Next.js, React, Vue, SCSS/Sass, Webpack, MySQL, PostgreSQL, MongoDB, Linux, Docker, Nginx and API integrations. I am also interested in web application security and tools such as Kali Linux and sqlmap, which helps me pay closer attention to input handling, database access and defensive backend design.

Where I add value

I try to be useful not only by writing code, but also by making implementation, architecture, integrations and delivery easier for a team to reason about.

Backend depth

Designing APIs, database structures, integrations and business logic that remain understandable as the product grows.

Full Stack context

Connecting backend decisions with frontend requirements, user flows, release constraints and real product usage.

Production mindset

Thinking about performance, deployment, support and maintainability before problems become expensive.

Security awareness

Keeping common web risks in mind: SQL injection, access control, unsafe input handling and fragile integrations.

Technology toolkit

The same core stack I use across product work: PHP and Python backend frameworks, modern JavaScript applications, databases, infrastructure, API design and practical security awareness.

Engineering principles

A few practical principles I value in day-to-day development, especially when a product needs to evolve without turning every release into a risky rewrite.

  1. Choose practical architecture that solves the current problem and leaves room for change.
  2. Make integrations explicit, testable and easy to reason about.
  3. Keep business logic readable, because product code usually outlives the first release.
  4. Improve legacy systems gradually when a full rewrite has no clear payoff.
  5. Prefer predictable delivery, clear communication and small reliable steps.
