I can adapt to US time zones when needed. If you're looking for someone who understands both the technical and business side of AI, I’m ready to help.

I help companies build and scale backend systems that don’t break under pressure. I’m a Senior Software Engineer and Technical Lead with a track record of delivering production systems at scale. I’ve built an ads platform from scratch that handles 50M+ requests per day and processes gigabytes of data daily, so I’m comfortable operating in environments where performance, reliability, and clean architecture actually matter. My core expertise is in backend development using Laravel and Django, along with React on the frontend. I work extensively with PostgreSQL and Redis, focusing on API design, distributed systems, and queue-based architectures. I don’t just ship features, I design systems that remain stable and maintainable as your product grows. What you can expect working with me: - I move fast, but I don’t cut corners that will cost you later - I communicate clearly and proactively (async-friendly, minimal meetings) - I take ownership of problems, not just tickets - I push back when something doesn’t make technical or business sense I’m especially valuable for: - Scaling systems that are starting to struggle under load - Cleaning up messy architectures and reducing long-term tech debt - Building backend foundations for serious products (not prototypes that stay prototypes forever) I actively leverage AI tools (ChatGPT, Copilot, Kiro) to accelerate delivery while maintaining structure, clarity, and high engineering standards. I follow a Spec-Driven Development approach using Kiro. That means clear requirements, defined constraints, and structured execution before writing code. I don’t do “vibe coding” or guesswork; this reduces misalignment, avoids rework, and ensures what gets built actually matches business goals. I’m selective with projects. If you’re looking for the cheapest option, I’m not the right fit. If you want someone who can think, execute, and scale with your product long-term, we should talk.

I am a postdoctoral researcher and AI/ML engineer working on efficient sequence modeling using Reservoir Computing, especially Echo State Networks, for sign language recognition and human activity recognition. My work focuses on low-computation training, fast inference, and practical deployment on edge devices such as Jetson. I build end-to-end AI pipelines, including data preprocessing, modeling, evaluation, and deployment-focused analysis such as latency and memory usage. I am especially interested in Reservoir Computing, Edge AI, Time-Series Machine Learning, Human Activity Recognition, and Computer Vision. Alongside research and engineering, I help researchers and technical teams turn complex AI/ML work into clear, professional writing. My experience includes journal editing, grant writing, research reports, and technical documentation, as well as practical computer vision solutions such as CCTV analysis and face recognition for international clients. I am open to research collaborations, reviewing, talks, and part-time or remote engineering work related to AI systems.
