15+ Years of Building Technical Solutions

The Challenge

Client needed to migrate a large product catalog from WordPress/WooCommerce to Shopify. Initial assessment revealed thousands of data quality issues across product descriptions, pricing, categories, and metadata. Manual correction would have required months of work and significant labor costs.

Technical Approach

• Data Extraction: Built custom scripts to extract all product data, metadata, and relationships from WordPress database
• Transformation Pipeline: Created automated ETL process to transform WordPress data structure to Shopify format while preserving business logic
• Quality Detection: Developed data mining algorithms to automatically identify quality issues across entire dataset (missing data, formatting problems, broken references, pricing inconsistencies)
• Automated Correction: Built intelligent correction scripts that could fix common patterns of errors without human intervention
• Validation: Implemented comprehensive validation to ensure data integrity before and after migration

Technical Challenges Solved

• Handled complex product variations and nested category structures
• Preserved SEO-critical data during platform transition
• Automated detection of edge cases that would break imports
• Built preview system so client could verify transformations before going live

Business Outcome

Technologies Used

Python, MySQL, Shopify API, WordPress/WooCommerce database structures, ETL processes, automated testing, data validation

The Challenge

Enterprise recruiting platform (ApplicantStack) serving 1000+ companies needed DocuSign-like electronic signature functionality. External solutions were too expensive at scale and created dependencies on third-party services. Required legally-compliant solution with full audit trails.

Technical Approach

• PDF Generation: Built system to dynamically generate employment documents from templates with client-specific data
• Signature Workflow: Created multi-party signature workflows supporting sequential and parallel signing patterns
• Security: Implemented cryptographic signatures and tamper-evident sealing of signed documents
• Audit Trail: Complete logging of all document events (viewed, signed, declined, modified) with timestamps and IP addresses
• Integration: Seamless integration with existing ATS workflows and notification systems

Technical Challenges Solved

• PDF manipulation at scale (millions of documents)
• Ensuring legal compliance with electronic signature laws (ESIGN Act, UETA)
• Handling complex multi-party workflows (employer, employee, witnesses)
• Performance optimization for large document volumes
• Mobile-responsive signature capture

Business Outcome

Technologies Used

PHP, MySQL, PDF generation libraries (FPDF/TCPDF), cryptographic signatures, document workflow engines, email integration, mobile-responsive web interfaces

The Challenge

Land investment business (Schaefer Land Holdings) needed to reach property owners at scale across multiple channels. Existing marketing platforms couldn't handle required volume, didn't support all needed channels, and were prohibitively expensive at millions of touches per year.

Technical Approach

• Custom Email Engine: Built from-scratch email system handling high-volume campaigns with sophisticated deliverability management
• Multi-Channel Orchestration: Unified system managing email, SMS, ringless voicemail (RVM), and physical direct mail campaigns
• Campaign Intelligence: Smart sequencing based on recipient actions (opens, clicks, responses)
• Deliverability Optimization: IP warming, domain reputation management, bounce handling, spam complaint processing
• Integration Hub: Connected to external APIs for SMS (Twilio), RVM, and direct mail fulfillment
• Analytics: Real-time campaign performance tracking and ROI analysis

Technical Challenges Solved

• Maintaining high deliverability rates at millions of emails per month
• Rate limiting and throttling across multiple external APIs
• Handling failures and retries gracefully across channels
• Cost optimization (finding lowest-cost providers for each channel)
• Legal compliance (CAN-SPAM, TCPA, state regulations)

Business Outcome

Technologies Used

PHP, MySQL, Custom SMTP implementation, Twilio API, RVM APIs, Direct mail APIs, Campaign analytics, Queue systems, Rate limiting, Deliverability monitoring

The Challenge

Hardware company with innovative sensor technology needed mobile application to allow customers to view real-time sensor data, configure devices, and receive alerts. Company had firmware and ML expertise but no mobile development capability.

Technical Approach

• Mobile Framework: Using Flutter/Dart for cross-platform iOS and Android development
• Real-Time Sync: Building WebSocket connections for live sensor data streaming
• Device Integration: Connecting to backend API that aggregates data from distributed sensor network
• User Experience: Creating intuitive visualizations of complex sensor data
• Offline Support: Handling connectivity issues gracefully with local caching

Technical Challenges

• Learning Flutter/Dart ecosystem (demonstrates ability to rapidly adopt new technologies)
• Efficient handling of high-frequency real-time data updates
• Balance between feature richness and battery/data usage
• Integration with proprietary backend systems

Business Outcome

Technologies Used

Flutter, Dart, WebSocket/real-time data, REST APIs, Mobile UI/UX, Cross-platform development, IoT device integration

The Challenge

Enterprise recruiting platform needed sophisticated task management system to automate workflows and ensure critical tasks weren't missed. Required intelligent task generation, assignment, scheduling, and escalation.

Technical Implementation
