High-Scale Database & Backend Latency Optimization Sprint

Eliminate database timeouts, slash endpoint latency, and cut cloud compute costs before throwing more hardware at the problem.

$1,200 – $2,200
Flat Fee
The Problem

Slow queries, spike-induced connection pool exhaustion, unindexed join tables, and silent N+1 hydration loops that bog down your application and spike database CPU under load.

The Solution

Deep diagnostic utilizing automated query plan parsers and slow query log analysis, paired with my 15+ years of system architecture expertise to deliver copy-paste index patches, ORM rewrites, and caching blueprints.

Guaranteed Deliverables:

✓ Prioritized Performance Remediation Report ranked by latency impact
✓ Production-ready SQL migration patches (composite, covering, & partial indexes)
✓ ORM & query refactor blueprints eliminating N+1 memory hydration bottlenecks
✓ Concurrency deadlock & row-locking contention risk assessment
✓ Redis / In-Memory caching & cache-stampede mitigation strategy
Ideal For: High-traffic SaaS, e-commerce stores, and high-throughput APIs on MySQL or PostgreSQL.

02 TURNKEY QUALITY · 3 – 4 Business Days

In-Depth Codebase Health Audit & Turnkey CI/CD Quality Engineering

Expose hidden architectural debt, eliminate regression anxiety, and install enterprise-grade automated quality gates in your repository.

$1,500 – $2,800
One-Time
The Problem

Teams ship code without automated safety nets. Hidden type errors, circular dependencies, security vulnerabilities, and brittle manual deploys slow down velocity and cause production outages.

The Solution

A comprehensive static analysis health audit combined with a drop-in, zero-friction GitHub Actions CI/CD setup enforcing strict typing, automated testing, security scanning, and code styling on every PR.

Guaranteed Deliverables:

✓ Deep-scan static analysis audit (PHPStan Level 8 / Psalm / TypeScript strict)
✓ Architectural & SOLID compliance review (god-objects, boundary violations)
✓ Dead code & cyclomatic complexity mapping to reduce cognitive load
✓ Security vulnerability & CVE dependency exposure audit
✓ Production-ready GitHub Actions CI/CD workflows with caching & parallel test execution
✓ Custom baseline configuration allowing strict rules on new code without breaking legacy
✓ Actionable Markdown/PDF remediation roadmap to pay down technical debt
Ideal For: Engineering teams taking over legacy repositories, preparing for due diligence, or leveling up team engineering standards.

03 ZERO-UI AUTOMATION · 5 – 7 Business Days

Conversational AI & WhatsApp / Voice-to-App Automation Suite

Turn WhatsApp and voice notes into an interactive, zero-friction interface for your application.

$1,800 – $3,200 setup + $250/mo
Setup + Retainer
The Problem

Users and field teams avoid using complex software dashboards for routine updates. Data entry is delayed, operations lack real-time visibility, and customer engagement across external channels requires expensive custom mobile app development.

The Solution

A production-ready webhook and AI pipeline connecting WhatsApp directly to your backend APIs and databases. Non-technical users send voice notes, images, or chat messages; LLM structured-output schemas parse the intent, validate the data, and execute backend actions or return instant conversational answers.

Guaranteed Deliverables:

✓ Resilient, queued webhook engine (Laravel / Node.js) connected to Meta WhatsApp Cloud API or Twilio
✓ Speech-to-Text pipeline paired with deterministic LLM JSON schemas for structured data logging (expenses, leads, work logs)
✓ Conversational database query bot to query metrics and trigger backend jobs via chat
✓ Interactive action cards with native 1-click WhatsApp buttons for manager approvals (refunds, sign-offs)
✓ Multi-modal document & receipt OCR pipeline extracting key-value pairs from photos and PDFs
✓ Failover queues and human-in-the-loop fallback alerting for ambiguous requests
Ideal For: B2B SaaS, field operations, logistics, agencies, and companies seeking zero-dashboard workflows.

04 STRANGLER PATTERN · 3 – 5 Days per module

Legacy System Modernization, Modularization & API Decoupling

De-risk your legacy migration. Transform monolithic controllers into clean, documented, modern API modules.

$1,800 – $3,000 / module
Per Module
The Problem

Monolithic legacy applications (Core PHP, CodeIgniter, older Java/Laravel versions) block new mobile apps, React/Vue frontends, and third-party integrations. Full rewrites take too long and fail frequently.

The Solution

AST-assisted code migration and schema extraction to extract business logic into decoupled OpenAPI 3.0 specs, strict Data Transfer Objects (DTOs), and modern Laravel 13 API endpoints using the Strangler Fig pattern.

Guaranteed Deliverables:

✓ Domain boundary & dependency isolation separating database logic from presentation layers
✓ OpenAPI 3.0 (Swagger) interactive contract specifications as the single source of truth
✓ Type-safe DTOs and validation layers ensuring clean input/output boundaries
✓ Production Laravel 13 API resource stubs with controllers, middleware, and auth wrappers
✓ Strangler migration & zero-downtime traffic cutover plan with rollback safety
Ideal For: Businesses modernizing monolithic platforms while keeping active revenue-generating features running.

05 ONGOING RETAINER · Ongoing Monthly Retainer

Fractional Principal Architect & Async Engineering Quality Partner

Enterprise-grade architectural leadership and automated code quality guardrails for your engineering team.

$1,500 – $2,500 / month
Monthly Retainer
The Problem

Fast-moving startups lack a senior technical voice to prevent fatal architectural mistakes, unscalable database designs, or security vulnerabilities, but cannot justify a $250k+/year full-time Principal Engineer salary.

The Solution

An automated, custom-tuned PR agent that continuously audits incoming pull requests for strict architectural compliance, paired with weekly human architectural reviews, schema vetting, and async mentoring directly from me.

Guaranteed Deliverables:

✓ Custom-tuned automated PR review agent enforcing your team's architectural, SOLID, and security rules
✓ Weekly human architectural risk & database schema audit on critical pull requests
✓ Async technical RFC & system design reviews for upcoming complex features
✓ Direct Slack / GitHub technical triage on high-severity vulnerabilities & scaling questions
✓ Monthly prioritized technical debt roadmap to protect engineering sprint velocity
Ideal For: Seed to Series B startups with 3–15 engineers that need senior technical guidance and PR guardrails.

The Process

How sprints work from scoping to deployment.

Step 01

NDA & Scoping

I sign a mutual NDA, review your repository or query logs under isolated access, and lock down exact sprint objectives and timelines in writing.

Step 02

Deep Diagnostic & Implementation

I profile your queries, trace the bottlenecks, and manually engineer every index patch, refactor, or pipeline myself.

Step 03

PR Handover & Verification

You receive ready-to-merge GitHub pull requests, executable migration scripts, clear documentation, and a personal async walkthrough from me.

FAQ

Frequently Asked Questions

Why choose fixed-scope sprints over hourly consulting?

Fixed-price sprints align incentives for speed, quality, and guaranteed outcomes. You work directly with me—a Senior System Architect with 15+ years of experience, not an agency account manager or junior developers. You get clearly defined deliverables, concrete code artifacts, and explicit turnaround times without runaway hourly billing.

How is my codebase, data, and intellectual property kept secure?

I sign a mutual Non-Disclosure Agreement (NDA) before any repository or system access. All profiling and analysis run in isolated, zero-retention environments. Your code is never shared, stored elsewhere, or used for external model training.

What tech stacks and frameworks do you support?

My primary backend specialization includes PHP/Laravel, PostgreSQL, MySQL, Node.js, Python, Rust, and AWS cloud infrastructure (Lambda, RDS, EC2, SQS, Redis). I also support legacy platforms including CodeIgniter, Core PHP, and monolithic decouplings.

What happens after the sprint deliverable is completed?

Every deliverable includes ready-to-merge GitHub pull requests, executable SQL migration scripts, thorough documentation, and an async walkthrough video. I also provide a post-delivery QA review window to ensure smooth production deployment.

How quickly can we kick off a sprint?

Diagnostic sprints (Database & Codebase audits) can typically begin within 24 to 48 hours of initial scoping and repository access. Bespoke automation builds kick off within 3 business days.
