What I'm looking for

I seek senior engineering roles where I can lead cloud-native, full‑stack projects, apply DevOps and AI workflows, own end‑to‑end delivery, and work in collaborative teams focused on reliability, automation, and measurable impact.

I’m a Senior Software Engineer with 6+ years of experience building and scaling cloud-native, full-stack applications across finance, telecom, and enterprise tech. I specialise in taking ideas from prototype to production — designing architecture, building scalable APIs, crafting performant front-end applications, and automating deployment pipelines.

My core stack spans React, Angular, Node.js, Golang, and GraphQL, backed by SQL/NoSQL databases like PostgreSQL, MongoDB, and DynamoDB. On the infrastructure side, I work deeply with AWS (Lambda, EC2, RDS, S3, DynamoDB, Bedrock), sst, Pulumi, Docker, Kubernetes, and CI/CD using GitHub Actions and Prometheus-driven observability.

I’m passionate about simplifying complexity — from designing event-driven architectures to integrating AI/ML workflows (LangChain + Bedrock) that make systems smarter and teams faster.

Recent highlights include:
• Building Deploy (https://deploy.onglx.io), a Go-based CLI that automates AWS infrastructure provisioning for developers.
• Creating Prude (https://prude.onglx.ai), an AI-powered triage platform using AWS Step Functions, Lambda, and Claude-based message classification.

I thrive at the intersection of engineering and product impact — bridging technical depth with clear business outcomes.

Always open to collaborating on high-scale, distributed systems and AI-driven applications.
