Duy Dy Pham.

Principal Software Engineer · Hands-on Technical Lead

Over 10 years building, modernizing, and operating production software. During around five years at Money Forward, I have connected Ruby/Rails, platform engineering, and reliability with delivery ownership — from design and implementation to developing team capabilities.

Core expertise

From system design
to production operations.

I combine backend development with cloud engineering, distributed systems, and production reliability. My work spans hands-on implementation, integration coordination, release readiness, and enabling teams to operate their systems.

Architecture & Backend

System design, microservices, multi-tenancy, APIs, and Kafka / CDC integration. Ruby on Rails, Go, Python, and React.

Cloud & Reliability

AWS, Docker, Kubernetes, Terraform, CI/CD, Datadog, and k6. Migration, performance analysis, capacity planning, and recovery strategies.

Technical Leadership

Understand business needs, design solutions, plan development, and commit to timelines. Coordinate developers, QA, SRE, and database teams; establish workflows, mentor engineers, and teach production operations.

AI Engineering

OpenAI API, RAG, and LLM workflows. Apply Copilot, Claude, and Codex to planning, implementation, and PR review with organized context.

Education & certification

From an idea to a system
that runs effectively.

Four ways I work with clients and engineering teams. Scope and deliverables are agreed for each project.

01 / BUILD

Build systems from the ground up

From business requirements to architecture, development, and deployment. Consider cost and operational needs from the earliest design decisions.

Deliverables: working system, deployment configuration, and operations documentation.
02 / AUDIT & OPTIMIZE

System audit & cost optimization

Review architecture, infrastructure, and operations. Identify bottlenecks, develop a roadmap, and implement improvements to operating efficiency and cost.

Deliverables: assessment report, prioritized improvements, and implemented solutions.
03 / AGENT INTEGRATION

Customer support agent integration

Design agent-assisted customer support workflows, connect system knowledge and tools, and establish handoff to the responsible person.

Deliverables: integrated agent workflows and quality control procedures.
04 / TEAM ENABLEMENT

Development & operations training

Training grounded in real systems: software development, deployment, monitoring, and incident response. Combine hands-on practice with knowledge transfer.

Deliverables: workshops, documentation, and team operations guides.
03 / Projects
