Obsolete Runtimes & Security Vulnerabilities
Running End-of-Life PHP 5.6 or 7.x versions leaves production systems exposed to unpatched CVEs, breaks modern TLS compliance, and prevents cloud containerization.
Enterprise PHP Modernization
Modernize Legacy PHP Monoliths Without The Risky Rewrite.
Senior architectural refactoring for mature PHP systems. We isolate technical debt, upgrade runtime environments to PHP 8.x, refactor monolithic bottlenecks into resilient services, and ensure zero-downtime production migrations.
Target Audience: CTOs, VP Engineering, and Product Leaders running revenue-critical PHP backends • Principal Architect Oversight
The Operational Reality
Critical production bottlenecks that degrade reliability, inflate infrastructure spend, and stall engineering velocity.
Tight Coupling & Regression Paralysis
CodeIgniter 2/3 or home-grown procedural frameworks interweave SQL queries directly into presentation templates, making every bug fix a high-risk release.
Unbounded Memory Leaks & Scaling Ceilings
Legacy session management, synchronous batch workers, and lack of connection pooling exhaust Apache/Nginx worker pools under minor traffic surges.
Senior Engineering Methodology
Guaranteed by a principal software architect who intervenes only by exception, powered by autonomous delivery.
Phase 01
Dependency & Call-Graph Topology Audit
Automated AST parsing and runtime tracing to construct a complete map of database interactions, third-party APIs, and tightly coupled business rules.
Phase 02
Hermetic Contract-Driven Verification
Establish automated characterization test suites capturing existing production behavior before touching a single line of application code.
Phase 03
Strangler Fig Decoupling & PHP 8.x Upgrade
Incrementally carve out legacy domains into typed, modular services running on modern PHP 8.3 with JIT compilation, strict types, and robust dependency injection.
Phase 04
Zero-Downtime Migration & Edge Offload
Dual-write schema migrations, shadow traffic verification, and CDN/edge caching with Cloudflare Workers to eliminate origin database load.
Technical Scope & Production Deliverables
Every engagement is bounded by verifiable architectural criteria and production deployment verification.
PHP 8.3 Runtime & Static Typing Refactor
Systematic migration from deprecated procedural extensions (mysql_*, mcrypt) to modern PDO, strict typing, typed properties, and Composer autoloading.
Framework Decoupling (CodeIgniter / Custom -> Modern)
Refactoring spaghetti controllers and direct SQL queries into decoupled domain services, clean repositories, and PSR-standard HTTP middleware.
Zero-Downtime Database Schema & Query Optimization
Eliminating table locks, migrating schema with online DDL tools, adding compound indexing, and implementing read-write query separation.
Containerized CI/CD & Reproducible Staging
Dockerizing legacy applications to replace fragile pet-servers with immutable container images and automated testing pipelines.

Review Full Technical ResourceFrequently Asked Architectural Questions
Clear answers regarding scoping, pricing, confidentiality, and our written-first engagement model.
Why modernize rather than complete a full rewrite from scratch?
Total rewrites fail over 70% of the time due to hidden business rules, lost edge cases, and continuous scope creep. Modernizing via the Strangler Fig pattern preserves revenue and business continuity while delivering incremental improvements in production every sprint.
Can you work inside a proprietary, custom-built PHP framework with zero documentation?
Yes. Over the past 15 years, SazM has modernized dozens of undocumented PHP applications across e-commerce, ERPs, and custom enterprise portals. We use automated AST call graph extraction and characterization testing to reverse-engineer business logic safely.
How do you guarantee zero downtime during database migrations?
We use expand-and-contract migration patterns: creating new non-blocking columns/tables, deploying dual-write application logic, backfilling historical records in bounded batches, and swapping read queries only after verifying data integrity.
What is the engagement process and how do we start?
We work strictly in writing with zero sales pressure. Submit your project brief or repository details through our Project Discovery flow (/start). A principal software architect will review your stack and return a concrete architectural assessment, fixed scope, and timeline.
