I build the infrastructure production systems run on — and the services that run on it. 4+ years across AWS and Azure, including a live cross-cloud migration during the March 2026 Middle East regional outage with near-zero downtime. WHAT I DO ☁️ Cloud Infrastructure — AWS and Azure environments built from scratch. Reusable Terraform modules across dev/test/prod. Least-privilege IAM, private networking, and SOC 2 controls built in from day one rather than retrofitted before an audit. ☸️ Kubernetes & Delivery — EKS and AKS design, Helm charts, GitOps with Argo CD using App-of-Apps with auto-sync and self-healing. GitHub Actions pipelines with multi-arch builds and Trivy scanning inside the pipeline, not bolted on after. 📊 Observability — Full instrumentation, not just a dashboard. OpenTelemetry, distributed tracing with Jaeger, Prometheus with custom alert rules, Loki, and Grafana dashboards built for the questions your team actually asks at 3am. ⚙️ Backend & GenAI Pipelines — Python/FastAPI, Django, Node.js. Multi-tenant architecture with schema-per-tenant isolation. End-to-end LLM ingestion on Temporal — batch embedding, retry policies, vector databases — running unattended. 🌐 Networking & Production Firefighting — Routing protocols, VPC and Transit Gateway design, OpenVPN PKI, TLS termination, WAF, DNS, reverse proxies. When something is down and nobody knows why, this is the work I'm best at. 🚨 Backup, DR & Cross-Cloud Migration — Velero for cluster and persistent volume backups, database point-in-time recovery, geo-restore runbooks, and tested restore procedures. Live provider migration when it's needed. I've done this under real outage conditions, not just in a runbook. RESULTS - Migrated a client's full production workload from AWS to Azure with near-zero downtime during the March 2026 ME-CENTRAL-1 outage, while the region was unavailable and most teams in it were down for the better part of a day - Built complete backup and recovery for a production Kubernetes platform — Velero for cluster state and volumes, database PITR, and documented geo-restore runbooks, tested rather than assumed - Cut manual cloud operations ~95% with a serverless EC2 scheduling platform on Lambda, EventBridge Scheduler, and Terraform - Reduced order execution latency ~73% on a live automated trading system through Redis caching, async queue processing, and multi-broker integrations - Architected a multi-tenant SaaS platform on FastAPI and Keycloak SSO with schema-per-tenant PostgreSQL isolation and automated per-tenant provisioning - Reduced EKS attack surface ~90% with Calico micro-segmentation and Kyverno admission policies, and took the platform to full SOC 2 audit readiness - Eliminated ~90% of manual infrastructure setup and cut deployment time ~50% with standardized Terraform modules across AWS Organizations INDUSTRIES Fintech and algorithmic trading · Generative AI and document platforms · Healthcare (HIPAA identity infrastructure, 1M+ users) · Multi-tenant SaaS STACK Cloud: AWS, Azure · Terraform, Ansible Kubernetes: EKS, AKS, Helm, Argo CD, Istio, Calico, Velero CI/CD: GitHub Actions, GitLab CI, Jenkins Backend: Python, FastAPI, Django, Node.js, NestJS, Celery, Temporal Data: PostgreSQL, Redis, Elasticsearch, Qdrant Observability: OpenTelemetry, Prometheus, Grafana, Jaeger, Loki, EFK Security: Kyverno, Vanta, Trivy, SonarQube, Keycloak, WAF, OpenVPN Send me the problem rather than the job description — I'll tell you honestly whether I'm the right person for it, and what it will actually take.

What does an Apache Shirol specialist do?

An Apache Shirol specialist secures Java applications by implementing authentication, authorization, and session management with the Apache Shiro framework. This role focuses on configuring the SecurityManager to verify user identities and control access to protected resources. The specialist defines realms to connect application data sources with security logic and manages cryptographic operations for sensitive information. They integrate these components into the web request lifecycle so that permission checks occur automatically during user interactions.

  • Design and implement authentication flows that verify user credentials against defined data stores using Shiro realms. The specialist configures the SecurityManager to handle login attempts and manages the creation of Subject objects that represent current users. This process includes setting up password hashing and encryption strategies to protect stored credentials from unauthorized access or exposure.
  • Implement authorization rules that restrict application actions based on assigned roles and specific permissions. The specialist maps user identities to access controls and writes logic that checks these permissions before allowing execution of protected methods. This work ensures that only authenticated subjects with the correct privileges can view sensitive data or perform administrative tasks within the system.
  • Configure session management behaviors to track user state across multiple requests and maintain secure active sessions. The specialist selects and sets up a SessionDAO to store session data in memory, a database, or a distributed cache like Redis. They tune session timeouts and validation rules to balance security requirements with user experience while preventing session fixation attacks.

How to hire an Apache Shirol specialist on Upwork

Step 1: Post a job

Define your Java security requirements clearly to attract qualified candidates. Use the Job Post Generator powered by Uma™, Upwork's Mindful AI to draft a precise description in seconds. Describe your needs for authentication or session management, and Uma creates a tailored post. You can write a new post, update a saved draft, or reuse an existing post.

  • Specify whether you need help with SecurityManager configuration or Realm implementation for your application.
  • List required deliverables such as role-based authorization rules or custom SessionDAO setups.
  • Include details about your current Apache HTTP Server environment if integration is part of the scope.

Step 2: Evaluate candidates

Look for proof of hands-on experience with Apache Shiro components in Java applications. Uma can run instant video interviews and build shortlists with side-by-side comparisons to speed up this process.

  • Check portfolios for examples of implemented authentication flows using org.apache.shiro.subject.Subject.
  • Verify experience configuring CacheManager for session storage in high-traffic environments.
  • Review past work showing successful integration of cryptography features for sensitive data protection.

Step 3: Interview your top choices

Discuss technical approaches to security challenges specific to your project. Schedule and conduct interviews within Upwork Messages, which generates an immediate transcript and summary after each session.

  • Ask how they handle permission checks for protected resources within the application request cycle.
  • Discuss their strategy for managing session timeouts and storage persistence across server restarts.
  • Request examples of troubleshooting complex authorization failures in previous Shiro implementations.

Step 4: Agree on scope and begin work

Finalize deliverables like working authentication modules or documented configuration guides. Use Upwork Messages and the contract workroom for all communication and project management tasks. Identity verification, payment protection, hourly tracking, and project funds add security to every engagement.

  • Set milestones for completing Realm setup and testing authorization logic for key user roles.
  • Define acceptance criteria for session management behavior under concurrent user loads.
  • Agree on documentation standards for maintaining the Shiro security configuration post-launch.

Frequently asked questions

Is hiring an Apache Shirol specialist worth it?

For most businesses, yes: hiring an Apache Shirol specialist is worthwhile. This expert configures authentication and authorization rules directly within your Java application code. They manage session storage strategies to keep user data secure during active use. Their work prevents unauthorized access by enforcing strict permission checks on protected resources.

How do I evaluate Apache Shirol specialist candidates?

Evaluate candidates by asking them to explain how they configure a Realm to connect Shiro with your specific user database. A strong candidate describes how they wire the SecurityManager into web request handling so permission checks occur automatically during access. Look for examples where they defined role-based access controls for specific application actions.

What is the difference between Apache Shiro and Spring Security?

Apache Shiro offers a simpler API for authentication and authorization that works outside the Spring framework. Developers choose it when they need lightweight security integration without the heavy configuration overhead of Spring Security.

Can an Apache Shirol specialist handle session management?

Yes, this specialist configures the SessionDAO to define how Shiro stores and retrieves active user sessions. They set up caching strategies to improve performance while maintaining secure session timeouts for authenticated subjects.
