Mobile Developer at Umain.Eidra
I am an accomplished Software Engineer with over 25 years of experience building, deploying, and securing cutting-edge software. My expertise spans 12 years of Android development, 8 years of iOS development, and a strong foundation in full-stack web technologies and cloud infrastructure. Currently a Mobile Engineer at Umain.Eidra, my current technical focus is on mobile application security, penetration testing, and vulnerability research. By understanding how apps fail and how they are compromised, I help build inherently more secure systems. Throughout my career, I’ve believed in giving back to the dev community. I am a frequent international speaker and open-source contributor, having shared knowledge at stages including KotlinConf, CocoaHeads Stockholm, Latin Android Summit, PHP Brazil, and The Developer Conference. What I bring to a team: - End-to-End Delivery: Extensive experience in project planning, resource mapping, release management, and optimizing developer workflows. - Versatile Tech Stack: Deep mobile expertise (Native & Flutter) paired with solid backend capabilities (PHP/Laravel) and cloud infrastructure. - Security-First Mindset: Practical knowledge of cybersecurity best practices, use-case writing, and system design. Always open to networking with fellow engineers, security professionals, and tech enthusiasts.

SowCotton
July 1, 2020 – June 1, 2021
SOWCOTTON is a cotton screening software from the field using its own tag or canvas of the bale, with or without RFID technology. For feather bales, the system is the same, and it can be tracked by SAI label (bar code) or add an RFID tag with the same number as the SAI label. In this project, I optimized the entire deployment system from the repositories, added gitflow and a dynamic environment for each branch. Automated deployments for development and approval environments. Afterwards, a queuing system was implemented, for email notifications and real-time integrations with third parties.

Cultural Fit Analysis
The candidate's extensive experience across various companies and project types, including personal projects, demonstrates a broad interest in technology and a proactive approach to learning. Their roles as a speaker and coordinator at various conferences (PHP Conference, Wordcamp, The Developer's Conference) highlight a willingness to share knowledge and engage with the developer community. The certifications in AI and Scrum also show a commitment to continuous learning and process improvement. The diverse technical background, while strong, shows a significant amount of experience outside of pure mobile development, which could be a strength for cross-functional teams but might require focusing on the core Android domain for a specific Android role.
Soft Skills & Operational Fit
The candidate's experience as a Team Lead and Technical Training Coordinator, along with mentoring responsibilities, indicates strong leadership, communication, and collaboration skills. Their involvement in defining technical architecture and promoting TDD suggests a focus on quality and best practices. The diverse project background also points to adaptability and problem-solving capabilities.
