Yuri Zhang.

Physical systems.
Useful intelligence.

I lead broadband EMC power-amplifier development, working hands-on across hardware, firmware and system integration.

I also build local AI workspaces that connect engineering knowledge, production records and the tools teams use to get work done.

Engineering in context.

RF LAMBDA / PROJECT LEAD

Broadband EMC
power amplifiers.

From design to validation.

I lead technical development and execution, working with the team across RF hardware, firmware architecture, integration and performance validation.

ENGINEERING IN PRACTICE

Design & integration

RF chains, circuit analysis, firmware architecture, and thermal and mechanical integration.

Test & troubleshooting

PA and LNA characterization, board-level repair, fault isolation, tuning and verification after rework.

Control & bias

Investigated unstable bias through control behavior and measurements; verified the change with RF checks.

Thermal behavior

Used temperature-controlled measurements to investigate how mounting and thermal contact affected performance.

Intermittent faults

Reproduced a delayed power fault, traced the supply circuitry and verified board-level rework through extended-load checks.

RF LAMBDA / PLATFORM DEVELOPMENT

Local AI for
engineering teams.

Connect technical knowledge with the work happening across engineering and production.

At RF Lambda, I design and build an on-premises platform that brings engineering documents, test data and SAP production records into shared workflows—from finding evidence to tracking assignments and reviewing completed work.

BUILT AROUND DAILY WORK

Knowledge & evidence

Connect Confluence documentation, test records and unit context. Keep supporting sources available for engineering review.

Production workflows

Develop SAP record synchronization, work assignments, milestones, morning summaries and team-lead review flows.

Work history & collaboration

Bring personal tasks, work timelines, team communication and notifications into the same workspace.

Deployment & maintenance

Maintain local model services, role-based access, release updates and recovery workflows. Refine the platform with feedback from the people using it.

Tools with a point of view.

Built around evidence, clear decisions
and the people doing the work.

RF LAMBDA / RELEASED MVP

Design-change
intelligence.

Built an engineering change impact analyzer that compares product configurations, surfaces potentially affected units and presents the supporting evidence for review.

Configuration comparisonUnit traceabilityEngineering review
How the review works

Connect the change to its context

Compare schematic and component changes against product configurations and associated units.

Keep uncertainty visible

Separate potential impact, missing documentation and installed-version checks so an engineer can assess the evidence before deciding what to change.

INDEPENDENT PROJECT / CODEX SKILL

Coordinated
agent teams.

I built a reusable Codex skill that organizes development through CTO, product manager and engineer roles. Structured handoffs, configurable model routing and evidence-based review help coordinate parallel work with clear responsibility for delivery.

Task ownershipModel routingDelivery review
Inside the workflow

Define the handoff

Specify deliverables, acceptance criteria and one writer for each shared resource.

Choose and review

Python helpers prepare model-routing decisions and maintain team records. PMs review engineer results; the CTO coordinates across teams and handles final delivery.

Closer to the work.

Practical software for the bench
and the manufacturing floor.

MANUFACTURING / DATACON

Drawings to machine programs

Turn DXF geometry into reviewable dispensing paths and PCL programs, with visual editing and playback.

Project details

Developed coordinate extraction, dispensing-path planning, graphical route editing, rotation, history and whole-unit PCL export. Added existing-program editing and conversion back to drawings for review. Trialed generated paths and relative coordinates with the manufacturing team; reference selection and machine/process validation remain part of the engineering workflow.

MEASUREMENT DATA

RF test-data comparison

Find measurement records and compare S-parameters and production curves in a shared, read-only workflow.

Project details

Developed measurement previews, curve overlays and comparison markers. Improved file identification and metadata quality with feedback from the test team.

BENCH WORKFLOWS

Engineering Toolbox

Reusable RF calculations, link budgets, measurement-file organization and formatted reports.

Project details

Turned repeated bench calculations into utilities, demonstrated them to the team and incorporated requested improvements. Connected raw measurement parsing with reporting.

TEAM CONTRIBUTION

Computer vision for chip QA

Contributed to a team workflow for visual inspection during hands-on manufacturing training.

RF Lambda Internship

Electrical engineering internship with experience in digital circuit design and power amplifiers.

Across disciplines.

I’m an RF and microwave engineer with a background in electrical engineering and operations research. My work spans physical systems, industrial AI and the software that connects engineering teams.

I like following a problem from the bench into the workflow: understanding the signal or circuit, finding the right evidence, and building a tool people can use. That same approach shapes my work on manufacturing automation and coordinated AI agent teams.
