Infrastructure & Site Reliability Engineer | M.Sc. Computer Science (8.92 CGPA)
Founding-team mentality @ Xeniaone. Bridging Full-Stack Dev with Mission-Critical Reliability.

• 🎓 Academic Excellence: Master's in Computer Science from St Joseph's University (8.92 CGPA). Class topper in Machine Learning (91%).
• 🛠️ Production Ownership: Currently leading the XOS Infra V2 rollout for a 20-person startup, collaborating directly with the CTO on architectural strategy.
• 🛡️ Reliability Innovator: Architected a high-availability environment from scratch, replacing manual runbooks with automated, human-centric DR consoles.
• 💻 Full-Stack Foundation: Deep experience in React.js, .NET, and PostgreSQL, enabling a developer-first approach to infrastructure.
• 🤖 AIOps Enthusiast: Exploring local LLM inference (LM Studio) and automated failure analysis patterns.
• 🇳🇱 Global Mindset: Actively learning Dutch (A1/A2) for a targeted 2027 relocation to the Netherlands/Germany.

• GitOps Orchestration: Authored and maintained 39 Helm templates delivering a full-stack enterprise app via ArgoCD (self-healing/auto-sync/prune).
• PostgreSQL High Availability (DBRE): Deployed PostgreSQL 17 HA using Percona Operator/Patroni (3-replica anti-affinity). Managed pgBackRest pipelines (4-hourly incrementals to S3) with PITR, achieving sub-minute WAL archiving.
• Human-Centric DR Console: Built an interactive TUI (Whiptail) recovery tool featuring an 8-step guided wizard, real-time log tailing, and state persistence to minimize cognitive load during restoration drills.
• Advanced Observability: Implemented 47+ alert rules using Google SRE multi-window burn-rate patterns. Configured tiered log retention (3–90 days) and custom Grafana dashboards for deep system health tracking.
• Security & Hardening: Enforced zero-trust networking with 30+ NetworkPolicies (default-deny) and hardened workloads using readOnlyRootFilesystem and runAsNonRoot baselines.

• Continue.dev Issue #6191: Debugged HTTP 401 auth regressions in Groq/OpenRouter providers. Provided the reference solution now used by the community. Endorsed by core maintainers.
• [Banking-Ledger MVP] (In Progress): A personal project demonstrating transactional idempotency, audit trails, and restore-verification drills for high-integrity financial systems.
• Bitnami Labs - PR#1901 Patched Helm chart Server-Side Apply (SSA) rejections by explicitly mapping TCP protocols, ensuring full compatibility with ArgoCD and Flux.
• Bitnami Labs - PR#1900 Mapped and documented global (--all-namespaces) vs. restricted namespace controller deployment architectures for enterprise-grade RBAC.
• Bitnami Labs - PR#1892 Resolved GKE Warden admission controller constraints, unblocking production deployments for modern GKE clusters (v1.32+).

• Contributor to Bitnami Labs/Sealed Secrets Documentation and bug fixes
• CKA (Certified Kubernetes Administrator): Currently in preparation.
• SRE Principles: Deep-diving into SLO/SLI engineering and error budget management.
• Dutch Language: Learning A1/A2 to facilitate 2027 relocation.
