Solving Complex Problems.
Building Scalable Systems.
Hi, I'm Asher (Le Thanh Trung), a Senior Software Engineer with 6+ years of experience with scalable, production-grade distributed systems in Go, Python, Rust, C, C++, and C#, taking ownership from system architecture to Kubernetes deployments and deep observability.
Professional History
Fullstack Software Engineer
- Engineered an AI Seller Chatbot (Python, LangChain, MongoDB, Go) with RAG architecture, cutting customer support ticket volume by 63%.
- Spearheaded a Warehouse-as-a-Service transformation abstracting logistics systems into standardized Go REST APIs, driving 48 Billion VND in combined partner revenue.
- Developed high-performance backend microservices and real-time data pipelines in Go and Rust, deploying on Kubernetes with OpenTelemetry observability.
- Integrated legacy ticketing platforms with internal IAM systems to automate criteria-based ticket routing and eliminate manual overhead.
Software Engineer & Senior Technical Support Engineer
- Identified critical memory leaks and established OpenTelemetry distributed tracing across microservices, dropping production incidents by 84%.
- Architected Go-based backend services and REST APIs connecting internal platforms with major enterprise distribution partners.
- Containerized services with Docker on Kubernetes (GKE), optimized high-volume PostgreSQL schemas/queries, and automated operations with Bash & PowerShell.
- Spearheaded full-cycle engineering practices to isolate recurring defects, hardening authentication flows via OAuth 2.0, JWT, and Microsoft Entra ID.
Technical Support Lead
- Led a team of 12 escalation engineers, architecting high-availability clustering (Windows Server Failover Clustering, MS SQL Always On) for tier-1 international banking clients.
- Built automated application health monitoring pipelines in Python and PowerShell to accelerate incident acknowledgement and response.
- Conducted deep-level code debugging for C/C++ and .NET services using WinDbg, ETW, and memory dump analysis to resolve root causes.
Technical Support Engineer
- Diagnosed and resolved complex server infrastructure, storage, and networking incidents for enterprise customers.
- Validated RESTful APIs and .NET Web services using Postman and custom automation scripts, cutting resolution times.
- Configured proactive observability dashboards and alerting with Prometheus, Grafana, and the ELK Stack while troubleshooting hybrid cloud TCP/IP networks.
