Hi, I’m Umair Ahmed, a senior software engineer with 8+ years of experience building scalable, high-performance web applications and cloud-native systems. I specialize in modern JavaScript frameworks (React, Angular, Vue) and backend technologies (.NET/C#, Node.js, Python), delivering secure and maintainable solutions across distributed architectures. I collaborate closely with cross-functional teams to translate business needs into technical outcomes, and I’m known for an analytical mindset, code quality, and mentoring others. I’m passionate about designing resilient architectures, improving team velocity, and shipping reliable software at scale. I’m authorized to work in the US for any employer. In my roles at Certus and ESTech Systems, I’ve led frontend and backend work, migrated services to Azure, built AI-powered chatbots, and helped teams adopt CI/CD practices. I enjoy mentoring engineers, pairing with UX and product teams, and turning complex requirements into actionable features such as course progress tracking, certification exams, hosted PBX, and secure access controls. I value security, performance, and user experience, and I’m always eager to learn, share knowledge, and push for better software outcomes.
