Platform Engineer
Professional Summary
Platform Engineer with a strong foundation in Rust and Python, specializing in building secure, highly scalable cloud infrastructure and automated developer workflows. Proven expertise in Infrastructure as Code (Terraform), multi-cloud migrations (AWS/GCP), and containerized deployments.
Technical Skills
Infrastructure & Cloud
Docker, AWS, Terraform
Backend
Rust (axum, tokio), Python, REST API, gRPC API, WebSocket, PostgreSQL
SysAdmin
Linux (Debian, Fedora), Bash, Nginx
Professional Experience
Platform Engineer
Freelance- Architected and deployed containerized infrastructure for independent client applications, designing automated CI/CD pipelines to ensure zero-downtime releases.
- Reverse-engineered multi-stage malware, publishing technical research on attack vectors and payload delivery to drive DevSecOps and Operations Security best practices.
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- Developed systems components in Rust, including custom runtime modules, unit tests, and performance benchmarks for a high-throughput transaction processing system.
- Provisioned and managed a globally distributed network of **60+ nodes across AWS EC2 and GCP using Terraform, enabling reliable production infrastructure across multiple regions.
- Executed a full cloud migration from AWS to GCP, maintaining infrastructure parity while minimising service disruption.
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.
