Work Experience

Backend Software Engineer

@

Unyte Health

Jan 2025 – Apr 2025

  • Maintained a serverless AWS backend (Lambda, API Gateway), PostgreSQL, CI/CD, and integrations (Stripe, HubSpot, TalentLMS) in partnership with engineers and PMs.
  • Designed an event‑processing layer to convert raw events into high‑level business events with a plug‑in registry for easy extension and backfilling; optimized for low latency.
  • Built a backfill framework that replays historical system events through existing event definitions, eliminating custom backfill scripts and reducing engineering effort to near zero.
  • Implemented two backfill modes: (1) exact synchronous replay for 100% accuracy; (2) dependency-aware replay using developer-provided relationships to infer correct event order, enabling much faster bulk backfills (processed ~4M events in ~2–3 hours on a small AWS EC2 instance; the synchronous approach would have taken days).
  • Introduced and repaired 10+ business event types, increasing tracked user interactions by ~30% and improving report accuracy for product and marketing.

Systems Engineer

@

AtkinsRéalis (formerly SNC‑Lavalin)

Sep 2023 – Sep 2024

  • Assisted the systems engineering team in managing documents, drawings, specifications, and requirements for the Eglinton Crosstown LRT project.
  • Built a PoC combining Neo4j with RAG (Sentence Transformers + SciPy) to query and trace requirements; enabled semantic search that returns relevant requirements in seconds; presented to the asset management team, director, and VP.
  • Trained a PyTorch model on the LTPP database to predict IRI (road quality), improving accuracy by 15.3% over baseline in cross-validated tests; presented to New Brunswick OM&R team.
  • Developed a Python package that abstracts and wraps the DOORS REST API, standardizing common operations and reducing boilerplate.

Robot Builder

@

Clearpath Robotics

Jan 2023 – Apr 2023

  • Assembled, tested, and calibrated robotic pallet stackers, performing mechanical and electrical assembly, software provisioning, and sensor calibration (LiDAR, encoders).
  • Contributed to a team output of approximately 3 units per week, ensuring robots met strict quality and performance standards before shipment.

Projects

Real-Time Operating System for STM32F4

|

Rust, C, Assembly, I2C, SPI, UART

github.com/levirogalla/rust-stm32-rtos

  • Preemptive multitasking RTOS for STM32F4 with ARM Cortex-M4 processor, implemented first in C and re-implemented in Rust; includes round-robin scheduling, context switching, and basic synchronization primitives.

Project Manager CLI

|

Rust, GitHub CI/CD

github.com/levirogalla/donna-cli

  • Rust CLI that bootstraps projects, organizes repositories via symbolic links, and standardizes CI with GitHub Actions; saves ~5 min on project creation and ~2 min to open/find projects in my workflow.

Truss Analysis

|

Python, PyTorch

github.com/levirogalla/truss-analysis

  • Python package to compute truss internal forces and optimize member dimensions using PyTorch autograd for gradient-based optimization under applied loads.
