Deployed a 10-service polyglot microservices platform (Go, Java, Node.js, Python, PHP) on a self-hosted bare-metal Kubernetes cluster using Helm and GitOps practices. Managed the entire cluster state declaratively with ArgoCD, enabling automated synchronization and self-healing drift remediation. Designed and implemented independent GitHub Actions CI/CD pipelines for all 10 services, where each pipeline built and tagged Docker images with the Git commit SHA, pushed images to Docker Hub, and automatically updated per-service image tag overrides in the GitOps repository for independent ArgoCD-driven deployments. Resolved multiple upstream build issues, including replacing the deprecated openjdk:8-jdk image with a multi-stage maven:3.8-eclipse-temurin-8 build and upgrading the Go dispatch service to fix a broken pprof dependency. Deployed and tuned the kube-prometheus-stack via ArgoCD for an 8GB VPS environment, created custom ServiceMonitors, and instrumented cart and payment services with prom-client metrics (counters, histograms), validating observability end-to-end in Grafana using PromQL queries.
LogSense — ML-Powered Log Intelligence System
Built an NLP-powered log intelligence and MLOps platform that reduced infrastructure MTTR by ~45% through automated anomaly detection, issue classification, and root-cause analysis on infrastructure logs. Designed the complete ML pipeline using MLflow, DVC, and Airflow, containerized FastAPI-based inference services, and integrated intelligent alert routing with Slack, Microsoft Teams, and PagerDuty to reduce alert fatigue and improve incident response efficiency while keeping all models self-hosted for cost optimization and data privacy.
Designed and provisioned Development, Staging, and Production environments during the migration from Node.js to Java Spring Boot; built and secured Ubuntu infrastructure with Java, Maven, Docker, PostgreSQL, Redis, Apache Kafka, Node.js, and NGINX

Mediatiz Foundation· EdTechOct 2025 — Apr 2026- Managed AWS infrastructure (ECS/Fargate, RDS, ALB, CloudFront, CloudWatch, SES, Route 53) for Mediatiz LMS and Khudi App serving 1M+ users with 20–30K concurrent requests at peak load; sustained 99.9% uptime
- Reduced AWS cloud costs by 30% through CloudWatch-driven auto-scaling, ECS task-definition tuning, and workload-aware right-sizing across staging and production clusters
- Built GitHub Actions CI/CD pipelines for Android (APK/AAB), Laravel LMS, Django, and Next.js admin dashboard with zero-downtime ECS rollouts, Slack deployment alerts, and Google Play Console automation; eliminated manual release-engineering overhead
- Architected and deployed PyBot – a Django + Ollama (Gemma 2B) local LLM tutor running on self-hosted infrastructure – eliminating external LLM API costs and addressing data-residency requirements for student PII
- Built serverless Slack-to-Google Sheets automation on AWS Lambda, API Gateway, EventBridge, and S3 for daily cross-departmental reporting across 8 departments; replaced a manual workflow
- Ran in-house security testing on lms.mediatiz.org (brute-force, SQL injection, CSRF) using Kali Linux, SQLMap, and SonarQube; validated WAF rules and produced remediation reports adopted by the development team
- Configured CloudFront + S3 origin for low-latency PDF lecture delivery (RoboVive LMS); integrated JazzCash and HBL Pay gateways and AWS SES (SMTP credential rotation, SPF/DKIM hardening) into production
- Authored the internal LMS DevOps Automation Roadmap and built CloudWatch dashboards covering ECS cluster health, RDS performance, and cost tracking

Poshmaal Technologies· Enterprise & SaaSDec 2023 — Oct 2025- Firefly.online – AWS to On-Premises Migration: Led end-to-end migration of an IoT SaaS platform (Node.js, React, PostgreSQL) from AWS to self-managed bare-metal infrastructure using a Blue–Green deployment strategy; replaced EC2, ECS, RDS, ALB, S3, CloudFront, Lambda, and Redis with fully self-hosted equivalents • Executed full data migration – PostgreSQL databases, Redis persistence, and object storage – with zero customer-facing downtime; reduced infrastructure spend by ∼60% while improving operational control and deployment flexibility
- Platform Rebuild & Production Infrastructure: Designed and provisioned Development, Staging, and Production environments during the migration from Node.js to Java Spring Boot; built and secured Ubuntu infrastructure with Java, Maven, Docker, PostgreSQL, Redis, Apache Kafka, Node.js, and NGINX • Built GitHub Actions + SonarQube CI/CD pipelines automating code-quality checks, Docker image builds, and environment-specific deployments; configured Nginx upstream load balancing for multiple backend instances • Deployed full-stack observability with Grafana, Prometheus, Loki, and Node Exporter for real-time monitoring, centralized logging, and alerting; hardened all environments with SSL/TLS (Let’s Encrypt), UFW, Fail2ban, and SSH key restrictions
- ERP Platform – Kubernetes GitOps Infrastructure (TransIP): Architected and deployed a production-ready K3s cluster on TransIP; provisioned servers, networking, and cluster resources for ERP workloads spanning C2B, B2C, and C2C business domains • Deployed and maintained 10+ microservices on K3s with environment isolation, ingress routing, scaling policies, and service-to-service networking; implemented Argo CD GitOps for automated, version-controlled deployments and consistent release management across environments
