Independent applicant portfolio · Hadrian

Forward Deployed
Engineer

Customer-facing software for shipyard operations, production systems, and aerospace engineering.

I work with stakeholders to turn operational requirements into deployed software, connecting the people, data, and physical systems needed to get work done. My experience spans full-stack planning tools, embedded controls, and automated engineering analysis.

Why I want to build at Hadrian

I want to strengthen America’s ability to manufacture the systems it depends on. Hadrian’s mission connects that ambition to work I want to own: learning a customer’s production reality, building what is missing, and improving the software as people use it. I want to grow my engineering career alongside the operators and engineers making American industrial capacity more capable and dependable.

My public LinkedIn is unavailable during a current contract. This portfolio brings together my engineering experience, implementation details, and résumé.

Shipyard Operations Software

Software Engineer

Make a disrupted production plan actionable.

Built and deployed a planning application around installation dependencies, parts, personnel, and shared resources. Planners can trace what a disruption affects and evaluate schedules against the constraints of the work.

ImplementationReact · TypeScript · Rust · Python · FastAPI · PostgreSQL · OR-Tools CP-SAT · Docker

Operational result
O3 and its defense-industry partners began using the planning model as a framework for organizing upcoming shipyards and distributed shipbuilding.
Relevant to Hadrian’s FDE role
Customer discovery, full-stack implementation, operational data models, and iteration based on planner feedback.
How the work came together
Understand the operating model
An installation requires parts to be available, workers and shared resources to be assigned, and prerequisite work to be complete. I represented those relationships in a shared ontology so scheduling could account for more than calendar dates.
Build the application with AI assistance
Used agentic coding tools to implement a React/TypeScript interface and Rust/Python services backed by PostgreSQL. I owned requirements, scheduling logic, historical-replay validation, and deployment.
Respond to changing requirements
When planners needed late deliveries and unavailable equipment reflected in schedules, I extended the dependency model and scheduler to propagate the consequences through affected work.
Validate and deliver
Replayed historical schedule delays to validate revised behavior before release. Docker packaging, role-based access, event history, and audit records supported deployment and review.

Production Workflows & Robotic Controls

Embedded Systems Engineer · Disney contract

Turn creative requirements into reliable physical operation.

Worked directly with production stakeholders to deliver a multi-axis robotic control system, from custom electronics and firmware through integration and crew training. Alongside the controls, I built AWS-backed asset and resource-management workflows.

ImplementationC · ARM Cortex-M · CAN · AWS · Unreal Engine · Logic-analyzer debugging

Operational result
Delivered integrated systems under a fixed production deadline, with operating procedures and training for a nontechnical crew.
Relevant to Hadrian’s FDE role
Hardware/software integration, product judgment, communication with end users, and responsibility through deployment.
How the work came together
Translate the requirement
Producers supplied creative intent and production constraints. I turned those into coordinated motion using custom control boards, embedded firmware, CAN-connected actuators, and registration with digital models.
Choose the right resource model
An idle timer alone could interrupt work that was still in use. I designed cleanup and shutdown around asset ownership and active sessions, then tested both active and inactive scenarios.
Resolve an integration fault
Used a logic analyzer to isolate intermittent control latency to a control-loop deadline overrun. Moved scheduling to a fixed-rate timer interrupt and revalidated the motion sequence.
Make the system usable
Explained technical constraints to producers, documented operating procedures, and trained the production crew. Delivery included the people operating the system, not only its hardware and software.

AEROS: AI-Assisted Aircraft Design

Software Engineer · Aircraft Design & Analysis

Evaluate coupled airframe tradeoffs with engineering evidence.

Built a Python analysis workflow alongside aerospace engineers for a blended-wing-body aircraft program. The integrated wing and fuselage make geometry, structural mass, aerodynamic loads, and aeroelastic behavior interdependent.

ImplementationPython · NumPy · SciPy · OpenVSP · CalculiX · Automated analysis

Operational result
Screened hundreds of payload-specific variants, advanced three finalists to higher-fidelity analysis, and identified a trade-study design with approximately 24% lower structural mass than baseline.
Relevant to Hadrian’s FDE role
Aerospace domain learning, automated engineering workflows, technical judgment, and collaboration with specialists.
How the work came together
Learn the coupled problem
Worked with aerospace engineers to understand why changing structural weight also changes how the airframe carries loads and behaves aeroelastically. The software had to connect those analyses rather than optimize them independently.
Connect the analysis stages
Linked geometry, aerodynamic and structural solvers, and flutter assessment in a repeatable workflow for payload-specific design comparisons.
Preserve the basis for review
Retained solver outputs and validation records, checked results against published references, and flagged uncertainty so engineers could assess design changes with supporting evidence.

Pharmaceutical Workflow Software

Automation Lead

Support operational work with controlled, traceable data.

Built and supported a computer-vision and Swift iOS workflow for pharmaceutical identification and disposal, deployed across hospitals in a HIPAA-compliant environment.

ImplementationSwift · Java · SQL · Computer vision · Secure APIs · Access controls

Operational result
Delivered software used in pharmaceutical workflows, with validation and audit records supporting review of sensitive operational data.
Relevant to Hadrian’s FDE role
Production application development, organizational deployment, operational scheduling, and sustained support.
How the work came together
Implement operational rules
Translated requirements into Java application logic, SQL validation, authorization controls, protected data handling, and audit logging. Conflicting information was surfaced for review.
Support scheduling
Connected facilities, drivers, and pickup windows with route-cost prediction and constrained planning to support operational scheduling.

and repeatable testing.

Saddleback Robotics · 06/2021 - 06/2023

Co-Software Lead

Co-led a ROS 2 rover stack through field trials. Built React/TypeScript and Foxglove interfaces for telemetry and waypoint commands, and connected navigation to STM32 motor hardware through an asynchronous Rust driver.

Simulation, recorded-run replay, and Docker supported regression testing without requiring the vehicle for every change.

Field Research & Development

Conducted Apple AR/LiDAR research across field sites, configuring sensors, validating captures, and developing C software and repeatable collection protocols throughout a travel-based engagement.

Why Hadrian

Build what the
program needs.

The opportunity to configure and integrate Opus, build applications where a customer program needs more, and help useful solutions become reusable platform capabilities is why this role stands out to me. These examples show the experience I would bring to that responsibility.

Own discovery through deployment

I turned installation knowledge into a planning application, then changed its dependency model and scheduler when users needed delays reflected in their plans.

Build across the stack

React and TypeScript interfaces connect to Rust and Python services, PostgreSQL operational data, and constraint-based scheduling.

Use AI in implementation

I used agentic coding tools to implement the shipyard application while retaining responsibility for requirements, scheduling logic, historical-replay validation, and deployment.

Make product decisions with operational context

Resource cleanup needed to respect ownership and active sessions. An idle timer alone could interrupt work still in use, so the operating model shaped the implementation.

Communicate with the people operating the system

Production stakeholders supplied creative intent and constraints. I translated them into control requirements, explained technical limitations, and trained the crew.

Learn the domain deeply enough to build

AEROS required understanding the coupling between geometry, aerodynamic loads, structural mass, and flutter alongside aerospace engineers.
