Hi, I’m a senior DevOps engineer with 20+ years of experience deploying production-grade Kubernetes systems, including K3s single-node clusters and cloud migrations, with 1,500+ completed projects and a 5-star track record. I'll review your Helm charts, Dockerfiles, and GitHub Actions workflows, then set up a secure K3s cluster on your VPS with ingress-nginx, cert-manager, and metrics-server, hardening the firewall and API access. I’ll deploy all services as Kubernetes StatefulSets/Deployments with proper resource limits, probes, secrets, and internal networking, including MongoDB, Redis, and ChromaDB with persistent storage, while ensuring no public exposure of internal services. The GitHub Actions pipeline will use immutable image tags and production approval gates, with secrets managed via GitHub Actions secrets and Kubernetes Secrets—no hardcoded values. I’ll configure TLS certificates, MongoDB backups, and rollback procedures, then validate all endpoints before handing over runbooks and monitoring setups. I can start immediately after reviewing the repository and documentation.

Hi, I reviewed the project and the main requirement is to deliver a production-ready Kubernetes/K3s deployment path on a VPS for the full-stack AI real estate platform, including MongoDB, Redis, and AI services. I’ll implement this by refining Docker-based multi-service deployments on the VPS, normalizing Helm charts for a KSA production setup, and configuring ingress-nginx, cert-manager, and metrics-server. I’ll create secure Kubernetes Secrets, value files for VPS deployment, and a robust CI/CD flow with immutable tags. I’ll set up a StatefulSet for MongoDB, Redis as internal cache, and TLS via cert-manager, plus scheduled backups and web-portal health checks. You’ll get clear rollback commands, handover notes, monitoring, and a clean, repeatable process with easy management and fast incident response. Let’s discuss here now.

Day one I'd audit your existing Helm charts and Dockerfiles against K3s resource limits—32GB RAM across that many services means careful resource requests/limits tuning. I've done similar single-node production setups before, including a VPS build for an Australian company that went live in under 24 hours with KeyHelp, SSL, and custom firewall rules. I'd start with K3s install, ingress-nginx and cert-manager, then validate your current charts work with your actual service dependencies before touching CI/CD. If you can share SSH access to the VPS and repo access I can assess what needs refactoring versus what's already solid. Available to start whenever. More at ffulb.com.

Hi, I'd handle this using K3s with Helm because it keeps the setup lightweight and production-ready while avoiding cloud lock-in during the initial phase. The biggest improvement will come from isolating secrets, validating resource limits, and setting up immutable deployment gates before any migration. I worked on a similar platform where MongoDB StatefulSets and Redis cache needed fine-tuning for persistence, and the team had to adjust memory limits after load testing. The initial deployment stabilized after one rollback due to a misconfigured probe. Changes will be rolled out in isolated stages with GitHub Actions preview environments, and existing services will remain protected behind strict firewall rules and non-root Kubernetes access. Backups for MongoDB and ChromaDB will be automated and tested before going live. This setup ensures clean handover documentation, minimal downtime during rollbacks, and a smoother AWS migration later if needed. If the approach fits, I can review the existing setup and suggest the safest path forward. Thanks, Denis.

Hello, I will deliver a production-ready single node K3s deployment and CI/CD path for your full-stack real estate platform, validating Dockerfiles, Helm charts, GitHub Actions and deployment docs and implementing secure production runbooks. I migrated a multi service proptech stack from K3s to EKS for a client with 50k monthly active users. I will normalize and refactor Helm charts for KSA only deployment and update GitHub Actions to use immutable image tags, production approval gates and secure secrets handling. My secret management approach is to keep secrets only in GitHub Actions secrets and Kubernetes Secrets, rotate any exposed keys, and optionally use sealed secrets or an external secret manager for long term ops. Estimated timeline: 10 to 14 days for review, deploy, smoke tests and handover. My prelaunch security checklist includes firewall and SSH key only, restricted Kubernetes API access, RBAC and network policies, image scanning, cert manager TLS, rotated credentials, offsite MongoDB backups and documented rollback commands. If you sign the NDA and share repo access I will deliver a written list of deployment blockers, Helm/value fixes and a rollout checklist within 48 hours, free and no commitment. Happy to jump on a quick chat. Ali Zain

Hello, "single-node K3s" deployment on your VPS is the core of getting your real‑estate platform into production safely. I’ll refactor the Helm charts to use immutable image tags and a dedicated values file for the KSA‑only deployment, then configure ingress‑nginx, cert‑manager with Let’s Encrypt, and a hardened firewall – this ensures zero‑downtime rollouts and secure TLS for all public routes. My stack includes Docker, Kubernetes (K3s), CI/CD via GitHub Actions, and Linux hardening, so I can set up the StatefulSet for MongoDB, Redis cache, and persistent ChromaDB storage while keeping secrets in Kubernetes Secrets and GitHub Actions. Looking forward to working with you. Artur Giżycki

K3s on a single-node VPS for multi-service AI/real estate calls for early attention to cluster security and stateful resource persistence—especially with MongoDB and ChromaDB sitting on VPS storage. Helm charts, secret handling, rollback plans, and airtight CI/CD are where real risk sits. I put two complex SaaS stacks into production last quarter on Kubernetes (Helm-based): the most recent included Node, Python/AI, TLS/full GitHub Actions CI/CD, plus a MongoDB StatefulSet with automated offsite backups, cert-manager for auto-rotating SSL, and custom ingress rules—details on a call under NDA. My approach: I review all Dockerfiles, Helm values/templates, and GitHub workflows first—patch image versioning, tighten probes, standardize secrets in GitHub Actions/K8s, and check no secrets drift to Git. I document every firewall, SSH config, and RBAC permission, with handover scripts and rollback/runbooks tested against a clone environment. Do you already have a preferred offsite storage for MongoDB backup, or should I integrate an S3-compatible target? Pradeep
