Josip B.

I am a Data & Martech Engineer with extensive experience in designing and implementing scalable data pipelines, marketing technology solutions, and analytics platforms for both startups and enterprise clients. I specialize in bridging the gap between technical engineering and business outcomes, helping organizations turn complex data into actionable insights and measurable results. Over the years, I have developed deep expertise in Python, Google Cloud Platform (GCP), BigQuery, Airflow, Terraform, Azure, Retool, and Google Ads Scripts, as well as modern marketing automation platforms, BI reporting, and campaign optimization tools. My work consistently focuses on reducing manual effort, increasing operational efficiency, and enabling data-driven decision-making for marketing and business teams. In my role at SeekandHit, I designed and implemented a cloud-based data warehouse that centralized marketing insights for large e-commerce businesses, enabling long-term data retention, improved ad performance measurement, and automated reporting. I built custom connectors and ETL pipelines using Python and GCP Cloud Functions, integrated client reports via Cloud Pub/Sub, and implemented ad spend anomaly detection systems using Google Apps Script and Slack alerts — all at zero additional tooling cost. I also mentored colleagues, sharing knowledge about data engineering best practices and guiding the adoption of a newly established role within the company. Additionally, I collaborated closely with marketing teams, providing technical consulting, understanding operational challenges, and designing solutions that directly supported business objectives. At JobCloud, I focused on data warehouse optimization and infrastructure cost reduction, achieving savings of $1,000 per month through query optimization and storage improvements. I developed attribution and Marketing Mix Models (MMM), orchestrated pipelines using Cloud Workflows and Cloud Dataform, and created dashboards for BI reporting that empowered teams to make informed decisions. Beyond professional work, I have significant web development experience, designing and delivering applications for educational and social impact projects. I built a web app for children to map emotions and competencies (Erasmus+ funded) using HTML, CSS, and vanilla JavaScript, and developed custom web apps for NGOs to manage volunteers and donation campaigns, integrating front-end interfaces with backend systems. I have experience with React, Firebase, AngularJS, and PHP/Symfony for building both interactive and data-driven applications. Additionally, I have taught web development to high school students, delivering workshops, mentoring sessions, and project-based learning, helping students gain practical skills in JavaScript, HTML, CSS, React, and Firebase. I hold a degree from FESB, where I gained a solid foundation in computer science, data structures, algorithms, and software engineering principles. Throughout my career, I have combined this technical knowledge with practical engineering, project management, and mentoring experience, consistently delivering high-impact solutions that meet client needs. My strengths lie in problem-solving, cross-functional collaboration, and translating business requirements into technical solutions. I am passionate about creating systems that are efficient, scalable, and maintainable, and I thrive in dynamic environments where I can contribute both as a hands-on engineer and a strategic consultant. Whether you need custom ETL pipelines, marketing analytics platforms, web applications, or AI-powered solutions, I can deliver high-quality, reliable work that aligns with your objectives. I am meticulous in coding standards, thorough in testing, and focused on producing measurable results that drive business growth. Let’s connect. I am ready to help you unlock the full potential of your data, marketing technology, and web platforms, creating solutions that save time, reduce costs, and provide a competitive advantage.
