About Dejan Rudić Vranić

WordPress Systems Integration Architect

After over 10 years building WordPress solutions for clients across three continents, the focus has narrowed to what delivers the most value: complex systems integration that requires deep technical expertise and production-ready architecture.

Dejan specializes in connecting enterprise systems like Salesforce, payment gateways, and custom CRMs to WordPress – the backend integration work that most WordPress developers avoid due to complexity.

Professional Background

From Civil Engineering to Digital Systems

Education:
MSc in Civil Engineering, University of Novi Sad

The civil engineering background provided valuable training in approaching complex systems methodically, anticipating failure points, and building solutions that maintain integrity under real-world conditions. These principles translate directly to software architecture.

Career Evolution

2010-2017: Foundation
Transition from civil engineering to web development began in 2010 as network and web administrator for the Heritage Protection Institute in Subotica. This period established fundamental technical skills and understanding of complex organizational systems.

2017-2020: WordPress Specialization
WordPress Developer at Better Collective, working on sports betting affiliate sites. This role involved scaling WordPress for high-traffic international audiences and complex content management requirements.

2020-2022: Integration Breakthrough
Lead Developer at Kroon Studio for teamsuisse.ch (now sporthilfe.ch). This project became the turning point – a complex platform connecting Salesforce, a custom Java CRM, payment gateways, and WordPress into one cohesive system for funding young Swiss athletes.

This project demonstrated where specialized expertise adds the most value: not in building generic WordPress sites, but in architecting integrations that handle real business complexity.

2022-2023: Corporate Infrastructure
Web Developer at Helium 10, maintaining and developing corporate website infrastructure. Experience working within larger organizational structures and enterprise-level requirements.

2023-2025: Agency & Technical Consulting
Backend Developer and Technical Consultant at DigitalSilk (US agency). This role involved client-facing technical sales, translating between business requirements and technical implementation, and delivering complex integration projects for agency clients.

2025: Innovation & Crypto
Innovation Team Member at Twognation, developing SEO-enhancing plugins and API integrations within the cryptocurrency domain.

2022-Present: Studio Agnis
Founded with Elena Vasić Petrović as professional structure for independent consulting practice.

Technical Specialization

Why This Expertise Matters

Most WordPress developers focus on themes, plugins, and standard implementations. The specialization here is different:

Complex Integration Architecture

• API integrations with business-critical importance
• Legacy system modernization (connecting older enterprise systems with modern platforms)
• High-reliability implementations where “mostly working” isn’t acceptable
• Custom business logic that doesn’t fit within standard plugin frameworks

Production-Ready Systems

• Understanding the difference between demonstration functionality and production reliability
• Implementing proper error handling, logging, and monitoring
• Designing for edge cases and real-world complexity
• Building systems that operate reliably 24/7 without constant intervention

Technical & Business Bridge

• Translating between technical implementation and business requirements
• Assessing risk and communicating it clearly to non-technical stakeholders
• Setting realistic expectations without technical jargon
• Knowing when to say “this approach won’t work” before implementation begins

Technical Capabilities

Platform Expertise:

• WordPress/WooCommerce core architecture
• PHP backend development
• JavaScript and REST API integration
• MySQL database optimization

Integration Experience:

• Salesforce (REST API, SOAP API, Bulk API)
• Payment processors (Stripe, PayPal, Payrexx, Authorize.net)
• CRM systems (HubSpot, ActiveCampaign, Pipedrive, custom platforms)
• Custom API development and third-party service integration

Architecture Patterns:

• Bidirectional data synchronization
• Webhook-based real-time updates
• Queue management for bulk operations
• OAuth2 and secure authentication
• Rate limiting and caching strategies
• Comprehensive error handling and retry logic

Working Methodology

Direct Specialist Access

Studio Agnis operates through a direct-access model. Clients work directly with Dejan from discovery through deployment and ongoing support. This structure ensures:

• Direct communication without intermediary layers
• Consistent quality with personal code review
• Complete project context and accumulated knowledge
• Personal accountability and reputation-based relationships

A selective client base (2-3 retainer clients plus 1-2 active projects) is maintained intentionally to ensure each client receives proper technical depth and attention.

Communication Approach

Geographic & Timezone:

• Based in Niš, Serbia
• Central European Time (CET)
• Overlap hours with US East Coast mornings and European afternoons
• Serving clients across US, EU, and Switzerland

Work Style: Primary communication is asynchronous (detailed written updates, Slack/email, Loom video explanations) with scheduled video calls for key discussions and alignment. This approach provides:

• Better documentation (everything written and reviewable)
• More productive deep work (fewer interruptions)
• Timezone flexibility (no requirement for middle-of-night calls)
• Clearer communication (ability to review and digest information thoroughly)

Urgent issues are addressed through pre-arranged communication channels when immediate response is required.

Honest Assessment Philosophy

Professional reputation is built on realistic expectations, not optimistic promises:

• Unrealistic timelines are identified and discussed upfront
• Lack of specific platform experience is disclosed immediately
• Complexity underestimation is addressed before project commitment
• Projects that aren’t a good fit result in referrals to appropriate specialists

Professional Experience Summary

10+ Years WordPress development experience
50+ Projects across three continents
Enterprise Systems Salesforce, custom CRMs, ERP platforms
Payment Integration Multiple processors and subscription systems
Industries Non-profit, e-commerce, government, cultural heritage
Languages English (fluent), Serbian (native)

Personal Background

Age: 43 years old
Family: Married to Elena, father of five children

The family situation provides practical understanding of:

• Managing complex schedules and deadlines
• Valuing reliability and systems that actually work
• Time management efficiency learned through necessity
• Long-term thinking and sustainable solutions

Outside Work:
Woodworking provides creative fulfillment and relaxation. The parallel between woodworking and software development is strong: both require careful planning, understanding of materials/systems, anticipating how pieces fit together, patience, precision, and pride in craftsmanship.
