Platform Engineer
I am a Senior DevOps, SRE, and Platform Engineer with over a decade of experience building, scaling, and securing infrastructure for high-growth platforms. My career has evolved from a deep-rooted foundation in security analysis and software development into a specialized focus on DevOps and Site Reliability Engineering. This unique background allows me to bring a developer-centric mindset to every project, ensuring that infrastructure is not just a landing zone for code, but a highly automated, secure, and cost-efficient engine for growth. Throughout my career, I have specialized in transforming legacy environments into modern, cloud-native powerhouses. My expertise spans the full automation lifecycle—from architecting secure AWS/GCP environments with Terraform and Ansible to implementing GitOps workflows with ArgoCD and GitHub Actions. I am particularly passionate about cloud financial management and observability; I have a proven track record of reducing operational costs by up to 30% and deployment latency by 50% through strategic refactoring and the implementation of robust ELK and Prometheus/Grafana stacks. I thrive in both onsite and remote environments, maintaining a strict commitment to delivering scalable, high-quality solutions with minimal supervision. I am fueled by a self-driven curiosity for emerging technologies and continue to build Python-based applications to keep my development skills sharp and my infrastructure strategies innovative.

Cultural Fit Analysis
The candidate has a diverse background working in various tech companies, from startups to large enterprises, and across different domains (AI video analytics, travel, video streaming, messaging, event tech). This breadth of experience suggests adaptability to different organizational cultures and challenges. The early career role as a Security Analyst, combined with later security-focused initiatives in DevOps/SRE roles (AWS WAF, IAM, Google Cloud Armor, secret management), indicates a strong interest and foundational alignment with a Cybersecurity role. However, the majority of recent experience is heavily skewed towards DevOps/SRE, which, while having security components, is not a direct cultural fit for a pure Cybersecurity role without further validation of deep security expertise.
Soft Skills & Operational Fit
The candidate's experience descriptions highlight strong problem-solving skills, incident management, 24/7 on-call participation, and mentoring junior engineers. These indicate a proactive and collaborative operational fit. The ability to work in fast-paced, high-traffic environments (Traveloka, Vidio, BBM) suggests resilience and adaptability.
