What I'm looking for

I’m looking for a role where I can build high-performance mobile and web systems, mentor developers, and apply LLM optimization to real products—ideally with a team that values clean architecture, measurable improvements, and fast iteration.

I build cross-platform mobile and full-stack web solutions with an emphasis on performance, clean architecture, and practical developer outcomes. As a Flutter Developer & Instructor at FlutterBegin, I’ve architected and deployed Flutter/Dart applications while optimizing rendering performance and state management to reduce operational overhead by 25%.

I’m also focused on scalable backend delivery and secure API design. As a Fullstack Developer (freelance/contract), I engineered web applications using MERN/PERN stacks, improving API response latencies by 30% through database indexing and query optimizations, and I implemented OAuth/JWT authentication with resilient REST APIs for concurrent user traffic.

Beyond traditional development, I work on AI training and applied LLM optimization. As an AI Trainer at Postwork.ai, I evaluate, debug, and optimize advanced LLMs for high-accuracy source code generation across Python, C++, and JavaScript, and I author verification test cases and precise code corrections to strengthen reasoning and algorithmic efficiency.
