Languages
Rust, Python, Bash
Systems
Linux (Debian, Fedora), Systemd, Nginx
Professional Experience
DevOps Engineer
Independent- Reverse-engineered a zero-click supply chain attack embedded in a VS Code configuration, isolating a multi-stage info-stealer and dismantling its IP-locked JWT delivery mechanism. Applied these threat intelligence insights to architect hardened CI/CD pipelines and infrastructure deployments with strict network egress controls.
Software Engineer
Codefy GmbH | Remote, Germany- Eliminated a critical performance bottleneck by replacing a third-party Java microservice with an in-house Rust service built with axum (Rust) and PostgreSQL. Analyzed the open-source Java codebase and replicated its behavior in Rust, reducing response times from 3+ seconds to under 200ms.
- Built document processing pipelines in Rust for automated legal workflows, including PDF editing, image transformation, and DOCX generation from Jinja template. Used lopdf and image libraries to handle format conversion, page-level image placement, and document compilation, reducing manual effort significantly.
- Engineered a Python web scraper to systematically extract and compile a comprehensive directory of German courts, automating the validation of 100,000 potential postal codes (PLZ) and associated cities (Ort) to aggregate the data into a structured CSV format.
Associate Software Engineer
Dhiway | Remote, India- Provisioned and managed a highly available AWS infrastructure of 60+ EC2 utilizing Terraform, implementing strict resource tagging and instance right-sizing to reduce monthly cloud compute expenditure by 28%.
- Deployed a centralized telemetry and log aggregation pipeline utilizing the Prometheus, Grafana, and Loki stack, configuring targeted alerting matrices that reduced Mean Time to Resolution (MTTR) for critical infrastructure incidents by over 35%.
Linux System Administrator
Trustforum | Remote, France- Managed and maintained Linux server environments, handling user permissions, package management, and system updates to ensure high availability for an early-stage community platform.
- Automated routine maintenance tasks, log rotation, and system backups using Bash shell scripting, reducing manual administrative overhead.
