Software Developer, SEO Expert & Founder MarWeb

About Me

Focused on one thing:
turning real business problems into scalable systems that deliver measurable results.

The background combines software engineering, technical SEO, and business, enabling a true end-to-end perspective — from architecture and performance to traffic, conversions, and financial impact.

Experience across 500+ projects in eCommerce, SaaS, B2B services, lead generation, and custom platforms means execution driven by outcomes, not experiments. Projects are handled from concept to production and continuous optimization, working directly with founders and decision-makers.


What makes the difference

  • Systems, not quick fixes
    Automating manual workflows, removing dependency on expensive tools, and optimizing infrastructure for real efficiency — not just theoretical best practices.

  • SEO treated as a product
    Architecture, indexing, performance, search intent, and conversion. SEO must support business goals, not just generate traffic.

  • Decisions driven by cost, scalability, and impact
    Thousands of euros saved monthly in operational costs and +60–170% growth in organic revenue through solid technical solutions.


Relevant experience

  • Custom platforms (eCommerce, marketplace, e-learning, SEO SaaS) built with Java Spring Boot, Next.js, Angular, PostgreSQL, and clean architectures (DDD, Clean Architecture).
  • Automation of critical flows: inventory, orders, shipping labels, transactional emails, content generation, and SEO reporting.
  • Moving websites from page 3–4 into Top 3 positions for high-intent commercial keywords.
  • Replacing Google Ads with profitable organic channels, reducing cost per lead by up to 50%.

Background

An initial background in business and accounting built a strong understanding of numbers, cash flow, and the real impact of technical decisions.
The transition into SEO and later engineering came naturally — many problems cannot be solved with tools alone, but require code, architecture, and automation.


Tech & Stack

  • Backend: Java (Spring Boot), Python, Node.js
  • Frontend: Next.js, Angular, React
  • Databases: PostgreSQL, MongoDB
  • Cloud & DevOps: AWS, Google Cloud, Docker, VPS
  • SEO & Analytics: Google Search Console, GA, GTM, Screaming Frog, Ahrefs
  • Integrations: Stripe, OpenAI, REST APIs

For projects where technology is expected to create real business impact, not just look good.
