ZENN — Digital Signature Platform, UIH

Architected and delivered a PKI-based digital signature platform that lets organizations sign, send, and manage legally-binding electronic documents through a developer-friendly API, compliant with Thailand's ETDA standards for trustworthy electronic signatures.

• PKI & HSM Security: Built the signing core on Public Key Infrastructure with Hardware Security Module (HSM)-backed certificate and key storage for enterprise-grade protection.
• Regulatory Compliance: Delivered ETDA Recommendation 23-2563 Type 2 e-signatures with E-KYC identity verification; platform certified to ISO/IEC 27001 and ISO/IEC 29110.
• API-Driven Workflows: Designed API-based signature positioning and both sequential and non-sequential signing flows with unlimited approvers, integrated with workflow systems such as BNG SmartFLOW.
• Multi-Industry Reach: Served government, banking & finance, insurance, and retail / e-commerce clients requiring compliant document workflows.

SmartTax - e-Tax Invoice / e-Receipt, UIH

Designed the platform that turns an organization's day-to-day transactions into legally-valid electronic tax documents — generating, signing, delivering, and archiving e-Tax Invoices and e-Receipts for submission to Thailand's Revenue Department.

• Standards-Compliant Document Engine: Built the e-File pipeline that converts business transaction data into XML conforming to ETDA standard ขมธอ. 3-2560 for Revenue Department submission, and into PDF/A-3 with the XML embedded for delivery to buyers and service recipients.
• Trusted Digital Signing: Signed every document with digital certificates and electronic signatures on the same PKI / HSM foundation as ZENN, so authenticity and integrity hold up to Revenue Department and audit scrutiny.
• Enterprise Integration: Exposed both REST API and SFTP ingestion so customer ERP and transaction systems could feed documents in real time or in bulk batches without changing their existing accounting workflow.
• Service Provider: Operated as a Revenue Department-registered Service Provider, submitting signed documents to the RD directly on the customer's behalf — so clients never had to build or certify their own RD submission channel.
• Host to Host (H2H): Shipped an H2H module offering the same RD submission capability under the customer's own credentials, letting organizations file directly with the Revenue Department in-house and avoid per-document service provider fees.
• Cloud Archive & Retrieval: Stored documents on standards-compliant cloud storage with Thai and English full-text search and role-based access, covering the full lifecycle from issuance through tax filing and statutory retention.
• Multi-Industry Reach: Deployed for retail & e-commerce, banking & finance, tourism & hospitality, and healthcare clients issuing invoices and receipts at high volume.

Hotel Search API, Agoda

Core API team member responsible for architecting and delivering a high-performance hotel inventory and availability platform serving full-year advance allotment and pricing data at global scale.

• Microservices & Event-Driven Architecture: Implemented a database-per-service pattern and integrated Apache Kafka for asynchronous data synchronization across multiple backend systems.
• Multi-DC Data Replication: Reduced cross-datacenter synchronization latency by 98% — from 5 minutes down to 5 seconds.
• Global Scalability: Scaled the system architecture from 3 to 5 Data Centers to support international expansion.
• High Throughput: Maintained high availability and resilience under sustained production traffic of 500 TPS.

Customer Dialogue Manager, FICO (Fair Isaac Thailand)

Contributed to FICO's marketing decision management platform that shifts organizations from product-centric campaigns to customer-centric engagement — orchestrating personalized, real-time offers across the customer lifecycle and every touchpoint.

• Technology Stack Build with Java EE, Primefaces, PostgreSQL as a config database and Vertica as a Data Warehouse & Big Data Platform.
• Interactive Dialogue & Decisioning: Built customer journey flows that drive both batch campaigns and real-time interactive conversations through an integrated decision engine.
• Omni-Channel Orchestration: Connected web, mobile, ATM, kiosk, social, email, and direct mail channels via pre-built and custom APIs for consistent cross-channel engagement.
• Real-Time Learning & Optimization: Applied adaptive control and A/B testing with predictive propensity models and contact / channel optimization to continuously refine offers.
• High-Performance Customer Data: Consolidated profile, account, transaction, and interaction data into columnar databases for low-latency decisioning at scale.
