Summary of Top 10 Accomplishments

1. Complete Modernization:
     PHP 5 → PHP 7 Upgrade

executed a full refactor and modernization of a large, legacy PHP 5 codebase. This included compatibility remediation, removal of deprecated features, re-architecting brittle components, and laying the groundwork for long-term maintainability. The upgrade was accomplished while keeping the system fully operational for municipalities using it daily for licensing, taxation, and compliance workflows.

2. Migration from Rackspace to AWS

led the end-to-end cloud migration of the production environment to AWS. This included designing the target architecture, containerization and infrastructure re-creation, data migration, cutover planning, and establishing operational practices. The move delivered major gains in reliability, scalability, monitoring, and disaster recovery.

3. Re-architecture into a True
    Multi-Tenant SaaS Platform

Transformed system from a single-instance monolithic application into a multi-tenant platform serving numerous municipalities under a unified, configurable architecture.
Key achievements included:

• Designing tenant-aware business logic and data structures

• Building tenant-scoped configuration and workflow engines

• Creating multi-tenant onboarding tools and deployment pipelines
  This allowed rapid addition of new cities and states with minimal engineering overhead.

4. Automation of Government Business Processes and Notifications

Automated complex, municipality-specific processes, including business license renewals, tax filings, delinquency workflows, and compliance notifications.
Improvements included:

• Background batch processors for high-volume filings

• Automated emails, notices, and workflow triggers

• Scalable job queues supporting large state-level workloads
  These changes drastically reduced manual intervention for both city staff and GovOS operations personnel.

5. Vacation Rental Compliance & Data-Collection Automation

Built the project-product that performed automated screen-scraping of vacation-rental marketplaces (Airbnb, Vrbo, etc.), matched listings to taxpayer records, and initiated tax compliance workflows. This system enabled municipalities to detect unregistered rentals, enforce compliance, and increase tax revenue through automated, repeatable processes.

6. Major Security Enhancements for Municipal and State Requirements

Large municipalities and state-level agencies required strict security controls.
Delivered:

• MFA and identity-integration upgrades (including Okta)

• WAF integration and hardened AWS infrastructure

• Secure workflow validations, audit logs, and permission controls

• Remediation of legacy vulnerabilities uncovered during penetration tests
  These improvements elevated the system to an enterprise-grade security posture.

7. Onboarding of New Municipalities at Scale

Designed and built onboarding tools, UI flows, configuration systems, and repeatable processes that enabled GovOS to bring new cities online quickly.
This included:

• Automated data-import and cleansing routines

• Tenant provisioning scripts

• UI components for city configuration and workflow definition
  Over time, onboarding moved from a manual engineering activity to an efficient, semi-automated operation.

8. Establishment of Robust DevOps, Monitoring, and Operational Tooling

Sstrengthened production operations with:

• CloudWatch, SNS, and alerting workflows

• Scalable log processing and background task queues

• Automated cron jobs, batch processors, and health-check systems
  This reduced outages, improved response times, and allowed the system to support large-scale state deployments such as Colorado SUTS.

9. Broad Architecture, Codebase, and QA Improvements

Across hundreds of engineering entries, the team delivered ongoing improvements including:

• Refactoring legacy workflows

• Building reusable common code modules

• Improving validator, form, and workflow engines

• Strengthening test coverage and QA processes
  These changes improved system stability and increased development velocity over time.

10. Training, Managing, and Transitioning to Off-Shore Engineering Teams

After the acquisition, the parent company required off-shoring engineering services.
We:

• Trained the offshore teams on the full codebase

• Built documentation, onboarding guides, and architectural reference materials

• Oversaw code reviews and development processes

• Stabilized delivery quality until the teams were capable of running development independently
  This ensured continuity of the platform and protected institutional knowledge during the transition.

Deliverables:

The Table Notification System suite includes

• PHP7 modernization and architecture
• AWS cloud migration framework
• Multi-tenant SaaS platform design
• Municipal licensing and permitting automation
• Tax filing and compliance engine
• Vacation-rental compliance data system
• Enterprise security and MFA upgrades
• AWS monitoring and DevOps tooling
• High-volume batch processing infrastructure
• Municipal onboarding and data automation
• Validation tooling and QA enhancements
• Offshore engineering knowledge transfer

Outcome:

Over more than four years, E7 Systems operated and evolved the platform to keep the company at the forefront of its industry, successfully supporting a rigorous acquisition review and managing the system through the transition and into the acquirer’s long-term operational model. The platform helped boost city revenues through faster, more certain collections, enabled governments to realize revenue that was previously unobtainable through manual enforcement, and strengthened the overall financial health of hundreds of cities and state agencies.
