What I'm looking for

I am looking for a role that fosters innovation and collaboration, where I can contribute to impactful AI projects and continue to grow my skills.

I am an innovative and passionate AI Full-Stack Developer with extensive experience in designing, training, and deploying cutting-edge intelligent systems. My strong expertise in Deep Learning (DL) and Machine Learning (ML) is complemented by in-depth knowledge of model architectures, optimization techniques, and algorithmic foundations. I have a proven track record in Natural Language Processing (NLP), Computer Vision (CV), and Generative AI, including hands-on experience with image processing models and large-scale AI deployments.

Throughout my career, I have developed LLM-powered onboarding assistants, built dashboards to visualize real-time code health metrics, and designed CNN-based anomaly detection systems to flag security vulnerabilities. My commitment to lifelong learning drives me to stay at the forefront of AI advancements, ensuring that I can tackle complex real-world problems effectively. I thrive in dynamic environments where I can leverage my skills in Python, mathematical modeling, and performance tuning to deliver impactful solutions.
