Douglas Teixeira Fabricio

I'm a Fullstack Software Engineer focused on web applications and driving measurable business growth. My core expertise spans across robust backend and frontend environments, utilizing mainly JavaScript and PHP, with some experience in NodeJS, NestJS, and Laravel, alongside containerized infrastructure such as Docker. I am passionate about crafting resilient systems, managing relational databases like MySQL, and seamlessly integrating modern APIs to solve complex, real-world constraints. I have a proven track record of leading high-impact initiatives that directly enhance user experience and operational efficiency. Recently, I spearheaded the development of a newly architected invoicing system, successfully migrating over 30,000 users to the updated platform. This rollout introduced advanced reporting, pre- and post-issuance validations, and seamless POS integrations. Beyond core product architecture, I have actively driven revenue growth by engineering targeted marketing triggers for free-tier users, significantly boosting lead contact rates and trial-to-paid conversions. My versatility extends to integrating AI-driven cloud solutions into internal tooling. By implementing audio transcription capabilities using Amazon Transcribe and Whisper, I enabled full-text keyword searches across sales and onboarding calls, dramatically accelerating pitch analysis and streamlining feedback loops. Whether migrating legacy users or deploying complex integrations, I thrive on delivering software that scales sustainably and empowers both users and internal stakeholders.
