A zero-downtime cloud migration, 60+ nodes, two platforms

At Dhiway, I provisioned and operated a globally distributed network of over 60 nodes across AWS EC2 and GCP using Terraform. When the decision came to migrate fully to GCP, I executed the migration while production stayed live. Centralized observability with Prometheus ran across the entire network throughout. No incidents. No service disruption.

A performance problem that needed a real fix, not a workaround

At Codefy GmbH in Germany, a third-party Java microservice was adding over 3 seconds of latency to every API request. I read through the open-source codebase, understood exactly what it was doing, and rebuilt it from scratch in Rust (Axum) and PostgreSQL. API response times dropped to under 200 milliseconds under production load. That is a 15x improvement on a live system.

Linux infrastructure and operations from day one

At Trustforum in France, I managed Linux server environments for an early-stage platform: user permissions, package management, system updates, log rotation, and automated backups via Bash scripting. The kind of unglamorous work that keeps systems healthy and teams uninterrupted.

Most infrastructure problems are not technical problems. They are judgment problems. Knowing which tool to reach for. Knowing when a system is healthy versus quietly failing. Knowing that the migration plan that looks clean on paper will not survive contact with production unless you have tested every assumption.

I have operated infrastructure where things going wrong had real consequences. That shapes how I approach the work. I do not build fragile systems and hope nobody notices.

Security is part of how I think about infrastructure, not something added at the end. Earlier this year I reverse-engineered a multi-stage malware attack that targeted developers through a fake job interview. It used obfuscated JavaScript, custom XOR and base64 encoding, IP-locked payload delivery, and a modular framework designed to silently extract credentials from developer environments. Tracing that attack changed how I think about secrets management, container hardening, and what a compromised environment actually looks like from the inside.

Rust Clippy

Clippy is the official Rust linter used across the entire Rust ecosystem. I contributed lints directly to the project, which required working through the compiler internals and the review process with the Rust team.

I am available for remote infrastructure and DevOps work: Terraform provisioning on AWS and GCP, Linux server administration, observability stack setup with Prometheus and Loki, and cloud infrastructure operations. As my Kubernetes work matures, I am actively moving into platform engineering and container orchestration.

I have worked remotely for companies in Germany, France, and India. I deliver work without hand-holding, communicate clearly across time zones, and take operational responsibility seriously.

Open to full-time remote roles and serious freelance infrastructure engagements.
