I have spent more than 8 years working remotely and I am comfortable delivering independently as well as within cross-functional teams. My core strength is solving complex technical problems and turning them into reliable, maintainable products. I have worked extensively with Java, Spring, Flutter, Android, JavaScript, and a wide range of backend, integration, and data-processing technologies. I have led and contributed to projects involving CMS platforms, mobile apps, OCR, facial recognition, fingerprint processing, resumable uploads, workflow engines, and low-code platform evaluations. I enjoy architecture, R&D, and hands-on implementation equally. Over the years, I have worked with distributed teams and clients in Pakistan, Malaysia, Thailand, Indonesia, and the UAE. I am used to adapting quickly to new stacks, business domains, and delivery expectations. I value clean engineering, performance, and practical solutions that scale. I have also trained teams, improved legacy systems, and helped modernize platforms by introducing better tools, patterns, and automation. I am open to opportunities where I can contribute as a senior engineer, technical lead, or architect, especially in roles that involve backend engineering, mobile development, platform modernization, or R&D-heavy problem solving. ##
