Building production AI agents
and enterprise tools.
Technology leader with 10+ years moving from hands-on engineering into technical leadership, building systems and teams across software, cloud infrastructure, enterprise operations, observability, and applied AI. I think in systems, not features - and I ship.
In my current role, I lead IT and applied R&D at Duoc Vuong Pharmaceutical, where my recent work focuses on turning messy operational workflows into reliable systems: ERP, HRM, LMS, CRM, BI/reporting, internal automation, and production AI agents. In parallel, I support Ecolab's enterprise observability and automation stack across the US, EU, Asia, and Greater China.
Interested in CTO, CIO, Head of IT, Solution Architect, or Technical Product Owner roles, especially where AI agents, enterprise automation, data platforms, and business systems connect directly with real operations. Open to remote and Hanoi-based opportunities.
Production patterns for making AI agents safer, more persistent, and more useful inside real operations.
Designed multi-agent and cross-session memory workflows that handle context-window limits, durable knowledge, hallucination control, data-security boundaries, secret handling, and prompt-injection risk in production-facing tools.

Cut manual quote latency from 42s to 4s by combining a TF-IDF prefilter, deterministic waterfall pricing logic, and Bot Framework proactive messaging. Production at Duoc Vuong.
AI and automation across ERP, HRM, CRM, eCommerce, reporting, and internal operations.
Connected previously separate business systems into a more coherent operating layer, where AI workflows can share context, trigger actions, support human teams, and reduce manual handoffs.
Business operating systems for purchasing, sales, accounting, inventory, logistics, people, and training workflows.
Built and rolled out enterprise systems that connect core operating flows across departments. ERP supports purchase-to-pay, order-to-cash, accounting, inventory, and logistics processes; HRM/LMS standardize employee records, approvals, onboarding, training assignments, and completion tracking.
Metabase dashboards and reporting marts for executive and finance operations.
Migrated Power BI-style reporting workflows into Metabase dashboards backed by PostgreSQL reporting marts, materialized views, freshness tracking, and filter-performance improvements across large ERP datasets. ClickHouse/dbt/Airflow pilot in progress.

Thang has played an important role in Duoc Vuong's digital transformation and technology foundation. He works professionally, takes strong ownership, and understands how to turn business requirements into reliable systems. His contributions to ERP, reporting, internal automation, and technology planning have helped improve operational visibility and efficiency across the company. I highly appreciate his structured thinking, responsiveness, and commitment to creating real business value.
Thang is an extremely talented technician. He indirectly reported to me at Ecolab during his time as a consultant with FPT. He was excellent to work with, very professional, and picked up new skills fast. His primary role was to help my team develop and deploy an enterprise application monitoring solution using AppDynamics. Despite being new to AppDynamics he quickly became a subject matter expert, which combined with his strong developer skills, made him a very valuable employee. I highly recommend Thang for future positions.
