What I'm looking for

I seek senior full-stack/AI engineering roles building scalable, real-time systems where I can apply ML, drive technical ownership, work in Agile teams, and deliver measurable operational impact.

I am a results-driven Full-Stack Developer and AI Engineer focused on building scalable, high-performance web and real-time systems that solve complex business problems.

I design and implement end-to-end solutions across e-commerce and public transportation, integrating modern frontends with robust backends and databases to deliver reliable platforms.

I have integrated AI/ML models for route optimization and demand prediction, implemented Celery for asynchronous processing, and led frontend efforts that reduced page load times by over 30% through optimization and lazy loading.

I thrive in cross-functional Agile teams, contribute to CI/CD and DevOps practices, and seek roles where I can combine machine learning with full-stack engineering to scale distributed systems and improve user experiences.
