About
I'm a Full-Stack Engineer currently driving cross-platform mobile initiatives at Devnnova, where I manage end-to-end deployment pipelines and optimize client-server performance.
My work spans real-time engines with WebSockets, relational database performance, B2B SaaS integrations, and product interfaces that make complex workflows feel approachable. I've also lectured at Chrisland University, breaking down production ML workflows for the next generation of engineers.
Clear boundaries, maintainable APIs, and database decisions that survive real usage.
Interfaces with thoughtful states, responsive layouts, and practical interaction details.
CI/CD, release paths, observability habits, and handoffs that keep teams moving.
Services
I can plug in at the product, frontend, backend, or release layer, then keep the implementation practical enough for a team to own.
Cross-platform iOS and Android apps with React Native, fluid native animations, and bulletproof EAS release management.
Secure, scalable RESTful APIs and real-time systems using NestJS, Express, WebSockets, and optimized PostgreSQL.
Embedded B2B platforms, custom e-commerce cores, and high-volume merchant dashboards including Shopify Apps.
Containerized microservices with Docker/Kubernetes and rigorous CI/CD pipelines for deployment confidence.
Production-focused data engineering pipelines, feature extraction, and model evaluation workflows.
From concept to deployed production app — wireframes, architecture, API design, and frontend delivery.
