I'm a Software Developer with over 3 years of experience. Over the years, I've built mobile apps that actually make business operations smoother—mostly focusing on ERP, Sales Order management, and Business Automation.
It's never just about writing code. It's about figuring out how that code solves real bottlenecks for the company.
Here is what I usually do to help businesses run better:
Making apps feel good: I spend a lot of time optimizing performance. Whether it's fixing UI lag or implementing lazy-loading for massive datasets, I make sure the internal teams get a seamless experience.
Connecting the dots: I smooth out complex workflows and data syncs so that daily operations are faster and more reliable.
Hardware integration: I have hands-on experience connecting mobile apps with external devices, like thermal printers, and tying them securely to backend services.
AI integration: I've built apps that leverage AI features like face recognition and license plate recognition to automate manual processes and make data entry much faster.
My daily drivers are Flutter, Dart, REST APIs, and Firebase. Right now, I'm also developing with Spring Boot and Full-Stack JavaScript so I can build better, end-to-end solutions.
