What I'm looking for

I'm looking to build scalable, secure, and maintainable software that solves real business problems, contributing across backend engineering, cloud deployment, DevOps, AI/ML, and end-to-end technical delivery.

I've led the backend architecture, system design, and DevOps delivery for SocialKnocks, a multi-tenant digital marketing SaaS platform supporting online stores, AI-generated content, marketing campaigns, and customer portals.

I build production-ready platforms across logistics, travel, and e-commerce, including Courier Walay and a multi-portal travel agency management system. My work covers FastAPI, Node.js, MongoDB, REST APIs, role-based access control, payment workflows, database modeling, and third-party integrations.

I take projects from requirements and architecture through live deployment using AWS EC2, Docker, Nginx, SSL, and Ubuntu servers. I also coordinate teams, manage sprints, and translate complex client requirements into maintainable technical solutions.

I'm also interested in AI/ML and computer vision, having built facial recognition systems and contributed to a NASA Space Apps Hackathon exoplanet-detection project using Python, OpenCV, light-curve processing, and XGBoost.
