What I'm looking for

I seek senior engineering roles where I can lead architecture and teams, drive scalable systems, improve delivery pipelines, and foster a collaborative, quality-focused culture.

I am a Principal Software Engineer and Tech Lead with 9+ years building scalable, high-performance web and mobile applications across diverse industries. I specialize in transforming business requirements into secure, efficient technical solutions using RESTful APIs, serverless computing, and both monolith and microlith architectures.

I have led cross-functional teams, improved deployment pipelines, and delivered measurable improvements such as reducing deployment time, optimizing databases, and increasing delivery velocity. Key achievements include building a granular RBAC system, optimizing MongoDB for millions of records, standardizing CI/CD, and architecting microlith systems adopted at scale.

I emphasize clean code, modern design patterns, and engineering excellence while fostering collaboration and continuous improvement. I am proactive in product discussions, improving code quality with tools like ESLint and Husky, and driving operational reliability through containerization and cloud services.
