About me
Intro
Java Backend Engineer | Spring Boot | Microservices | DevOps (Azure) | AI/ML Enthusiast I’m a Computer Science graduate and software engineer with hands-on experience in Java backend development, microservices architecture, and DevOps automation. My current focus is on designing scalable, secure, and event-driven systems using Spring Boot, RabbitMQ, PostgreSQL, and Docker. With a strong foundation in clean architecture and SOLID principles, I’ve implemented: -Microservices with RESTful APIs and message-driven communication using RabbitMQ -Containerized environments for PostgreSQL and messaging queues with Docker -CI/CD pipelines on Azure using GitHub Actions -Database migrations with Liquibase and caching via EhCache (L2 Cache) -Unit & Integration testing using JUnit and Mockito Previously, I worked on AI and Reinforcement Learning from Human Feedback (RLHF) with Outlier.ai, optimizing large language models through response ranking and feedback-driven fine-tuning. I also co-founded SmartQ, an AI-based startup recognized by NIC Sukkur (Cohort 5) for its innovation and real-world impact. I bring together backend engineering discipline, DevOps reliability, and a continued curiosity for AI-driven systems. Always eager to build systems that are not only functional but elegantly scalable.

As an AI enthusiast with hands-on experience in training SOTA large language models through RLHF, I have contributed extensively to the development and fine-tuning of cutting-edge AI systems. From Summer 2023 till today, I collaborated remotely with Outlier.ai, where I played a key role in tasks related to model training, response optimization, and data annotation. It was a remote responsibility but during my whole work experience, I worked on a variety of projects including coding, fixing AI model responses, and ranking correct answers to enhance model performance. I contributed to improving LLM outputs, providing valuable feedback, and ensuring AI models met high standards of accuracy and efficiency. My work in this space has deepened my expertise in AI, data science, and machine learning, and has strengthened my ability to work with complex datasets, as well as fine-tune AI models for optimal results. So yeah, My goal is to continue growing within the AI/ML field, applying my knowledge and skills to solve real-world problems and drive advancements in AI technology.
