About Me

Senior Software Developer

Jan Mark Salarda

With over 18 years of experience in building scalable, web-based information systems, I bring deep expertise in PHP, MySQL, and full-cycle software development (SDLC). My career began at a university, where I led the design, development, and deployment of a comprehensive suite of Management Information Systems—including Enrollment, Student Information, Facilities Reservation, OPAC, Payroll, and Gradebook—built entirely in pure PHP without frameworks, demonstrating advanced skills in custom backend architecture, database optimization, and secure application development.

As an IT instructor, I delivered a broad curriculum spanning programming fundamentals, object-oriented programming (OOP), web application development, systems analysis and design, and office productivity tools. This academic foundation sharpened my ability to architect, document, and implement complex, user-focused software solutions.

I later joined an outsourcing firm, contributing to high-impact international projects for enterprise clients. Key achievements include developing process and request management systems for Fujitsu Australia's data centers, as well as building web applications for lead generation, intellectual property management, photo galleries, and job boards using PHP frameworks such as Yii and CodeIgniter, applying MVC design patterns, RESTful API integration, and agile development practices.

Continuously committed to learning and innovation, I have expanded into Python and Django, creating automation tools, data scrapers, and bots for Amazon, Shopify, Etsy, and Instagram. I also integrate business intelligence and workflow automation tools including Odoo (ERP/CRM), Metabase, ClickUp, Airtable, Baserow, and Make (Integromat).

I am now seeking opportunities to contribute to large-scale enterprise information systems, where I can leverage my expertise in software architecture, database engineering, API integrations, cloud-based deployments, and process automation to drive meaningful business transformation and digital innovation.
