Architecture Consulting + AI-Augmented APIs

Quality. Efficiency. Integrity. Let’s build the right solution—before writing code.
I’m an API & Solutions Architect with 14 years of backend and integration experience, helping startups and established businesses design secure, scalable, and maintainable systems.
Over the years, I’ve worked extensively on API-driven platforms, SaaS integrations, and complex backend systems, where early architectural decisions directly impacted scalability, performance, and long-term cost. My focus is on helping clients make the right technical choices early, reduce risk, and avoid costly rework later.
I don’t just connect APIs—I design how systems should communicate, handle authentication, manage data flow, scale under load, and remain flexible as business needs evolve.
Clients typically work with me when they:
- Are planning a new API or integration
- Need to redesign or stabilize an existing system
- Are facing data sync, scalability, or reliability issues
- Want a second opinion before committing to development
- Need guidance choosing between custom builds vs automation tools (Zapier, Make, etc.)

My role is to analyze the problem, design the architecture, and guide implementation decisions—not just write code blindly.
API & Integration Architecture
- REST APIs, webhooks, and event-driven systems
- Bi-directional data synchronization
- Data mapping, transformation, and consistency
- Rate limits, retries, and fault tolerance

Authentication & Security
- OAuth 2.0, tokens, scopes
- Secure API access design
- Multi-system authentication flows

SaaS & Platform Integrations
- Zoho CRM / Zoho Creator
- Xero
- DocuSign
- Google APIs
- Keap (Infusionsoft)

My architectural work is backed by strong hands-on experience in:
- PHP & Python backend development
- Laravel framework
- Linux-based environments
- Custom business logic for CRM / ERP systems

Work Highlights
- Designed and integrated Zoho CRM with Xero, reducing manual data entry by 80%
- Automated DocuSign workflows using Python, saving 15+ hours per week for a legal firm
- Led the architecture and development of a Laravel-based ERP system with Zoho Creator integration for a manufacturing client

What You’ll Get When Working With Me
- Clear understanding of the best technical approach
- Architecture decisions explained in plain language
- Identification of risks and trade-offs early
- Practical recommendations you can act on immediately
- Clean, maintainable solutions aligned with your business goals

Whether you need architecture guidance, a consultation, or hands-on implementation, I focus on delivering outcomes—not just tasks.
If you’re planning an API integration, redesigning an existing system, or want clarity before development begins, I’d be happy to help.
Let’s focus on building the right solution first.
