What I'm looking for

I want a fully remote role where I can build secure backend systems and lead AI-assisted development with strong quality gates, validation, and human-in-the-loop safety—working with modern architectures and distributed systems.

I’m a Senior Software Engineer with 10+ years building production backend systems, and in the last 18 months I’ve led practical adoption of AI-assisted development workflows across enterprise projects. I’m a daily user of Claude Code, Cursor IDE, GitHub Copilot, and Claude/OpenAI APIs to generate, refactor, test, and document code.

I focus on quality gates, prompt engineering, LLM-output validation, and the security/licensing trade-offs of AI-generated code. At DemandBridge, I designed and shipped an AI-assisted operations pipeline with human-in-the-loop checkpoints for production use across 50+ customer environments, including prompt patterns, validation gates, and reusable libraries for incident triage and root-cause hypothesis generation.

I’ve also led architecture and modernization work, migrating a Java JSF monolith to AWS-native microservices (Spring Boot + ECS Fargate + RDS + S3), and coached engineers through AWS adoption and AI-tool onboarding. I mentor across LATAM, India, and Europe teams, helping others trust what’s safe, verify what matters, and ship reliable software.
