DEVOPS ENGINEER | GO + PYTHON DEVELOPER | RELIABILITY ARCHITECT

I turn complex infrastructure into high-confidence delivery engines.

I'm Mohammad Shafighi from Mashhad, Iran. I build and operate systems where uptime, velocity, and safety are non-negotiable. From Linux and cluster operations to Go/Python backend engineering, I own the path from idea to stable production.

What I Bring To Engineering Teams

        

          

            
Operator Mindset

            

              I think in failure modes, rollback paths, and operational clarity.
              I build systems that are understandable at 3 AM, not just impressive
              in architecture diagrams.
            

          

          

            
Builder Mindset

            

              I write production code in Go and Python, so I can improve both
              infrastructure and application layers without handoff friction.
            

          

          

            
Ownership Mindset

            

              I do not stop at deployment. I stay for performance tuning,
              monitoring feedback loops, and continuous reliability improvement.

DevOps Engineer — Done

            
Mar 2025 - Present | Mashhad, Iran

            

              I run the platform like it is mission-critical infrastructure,
              because it is. I manage Kubernetes and Docker Swarm clusters,
              optimize Linux and Proxmox environments, and keep services stable
              through observability, CI/CD automation, and well-practiced backup
              and disaster recovery strategies.
            

          

          

            
DevOps Engineer — Chimzy

            
Mar 2025 - Present

            

              I owned delivery and operations pipelines end-to-end: from GitLab
              workflow design to running production data services. My focus was
              reducing release anxiety and making deployments boring, predictable,
              and recoverable.
            

          

          

            
Information Technology Specialist — Cantoos

            
Sep 2018 - Nov 2019 | Pazh Tower, Mashhad, Iran

            

              I modeled business processes with BPMN2, contributed to the
              Cantoos BPMS platform, and worked on the website frontend using
              the company's proprietary platform plus HTML, CSS, and JavaScript.
              I also supported content operations, including website maintenance
              and visual content production.
            

          

          

            
Software Engineer — ICT Org Mashhad Municipality

            
Sep 2024 - Present | Mashhad, Iran

            

              I rebuilt architecture foundations for the Shahreman platform,
              developed core microservices in Go and Python, and redesigned key
              flows like authentication, monitoring, and data reliability. I also
              delivered an AI recommendation system that moved from research to
              accepted implementation.
            

          

          

            
DevOps Engineer — Part Software Group

            
Oct 2023 - Sep 2024

            

              This role sharpened my operational discipline: Linux stability,
              Bash automation, IaC-first thinking, and CI/CD collaboration. I
              focused on creating repeatable engineering workflows instead of
              heroic one-off fixes.
            

          

          

            
Developer & System Administrator — AftabNetwork

            
Feb 2020 - Jan 2024

            

              I moved between backend development and system operations,
              delivering Go/Python services while managing databases, replication,
              and monitoring. This hybrid role built my full-stack infrastructure
              perspective.
            

          

        

      


      

        
Flagship Project: Memorandum

        

          

            
Memorandum - Sharded In-Memory Data Store (Go)

            open repository
          

          

            Memorandum is my open-source response to restrictive database
            licensing trends: a self-hosted, sharded in-memory key-value store
            written in Go with TTL, WAL durability, and clustering capabilities.
            It demonstrates my ability to design internals, build network
            interfaces, and think about real-world operational trade-offs.
