Sergio Miranda La Hera

Designed and built a tail-sitter copter to stabilize an inherently unstable lift configuration. Developed a servo-actuated adaptive controller to control lift instability and implemented the embedded control logic. Produced and assembled the airframe from a precision CAD (CATIA) design to support flight-testing and validation.

Contributed to planning documentation and technical analyses for a satellite project. Authored a change and configuration management proposal defining the technical baseline and the change-control approach. Supported the team’s configuration governance required for project execution and engineering consistency.

Designed a spin-stabilized mini-satellite concept using optimal control methods for motion control. Built onboard image capture and wireless telemetry data transfer, and performed structural design validation using FEA. Developed a ground-station interface for payload data and telemetry as a basis for mission-operations style architectures.

Provided independent data engineering, DevOps/CI-CD, cloud architecture, and applied machine learning services across multiple client engagements. Built containerized CI/CD workflows and automated testing/deployment using Docker and Git-based practices. Implemented infrastructure-as-code for reproducible cloud environments with Terraform, Ansible, and CloudFormation on AWS and GCP, and delivered end-to-end data pipelines from ingestion to evaluation. Prototyped ML/computer-vision solutions using PyTorch, TensorFlow, and OpenCV, and developed ROS/ROS2 robotics software for sensor integration and control-node communication.

Owned the Euclid mission Level 3 data model used across the satellite science processing chain, representing CosmoStat-CEA Saclay within an international consortium. Advanced the data model architecture through multiple versions and ensured architectural consistency across 24+ Level III data products. Designed standards-compliant data structure definitions (FITS/XML/XSD) aligned with ECSS requirements and implemented CI/CD for the data model repository. Built supporting documentation and tools in Python, including a DPDD auto-generated from the data model for traceability and user reference.

Developed and analyzed railway surveying software as part of a scale-up to a multi-developer engineering team. Implemented core application components for Gedo Rec and Gedo Track using C++ and supported reliable releases through unit testing. Contributed to project planning by assessing scope and preparing a development plan aligned with team expansion needs.

Programmed C++ applications in support of the Unipin machine, focusing on the HMI layer and integration into an embedded processing platform. Implemented system integration work for new machine components and processing modules, including profiling, cutting, and gluing. Managed version control and issue tracking, and maintained automated test suites using Linux/Windows development workflows and Qt testing toolchains.

Developed real-time embedded software to bridge slower PC-based measurement workflows with higher-end oscilloscope-class DAQ instruments. Engineered measurement algorithms and delivered client-specific application variants aligned with instrument standards. Worked across C/C++ codebases with Linux/Windows tooling, using Git-based workflows and Qt-based development environments.

Built closed-loop motion control systems for a double-acting cylinder, combining embedded control logic with reliable actuator performance. Implemented operator interfaces and added hardware security features through dongle-based mechanisms for the electronics. Also handled supporting IT and server administration tasks, integrating web and tooling components across Windows Server and virtualization environments.

Provided technical support for preventive security measures across Linux, Windows, and macOS environments. Assisted with implementation and validation of security-system readiness activities, focusing on practical operational support. Supported troubleshooting and technical documentation related to the secured systems in use by the organization.

Contributed to designing a new company database framework and supported database verification processes. Assisted with data control tasks to improve reliability and correctness of stored information. Worked alongside engineering staff to implement and validate the new database approach during the internship period.
