Projects

Infra tooling, automation, and cloud-native systems.

Flume

github ↗

Flagship · Infra-aware workflow engine

Go-based orchestration engine that runs cloud-native workflows as DAGs. Integrates with AWS and Terraform to plan, apply, and coordinate infrastructure-aware pipelines. This website's deployment is orchestrated via flume.

Cloud script runner

Flask + Vue platform for uploading Python scripts, chaining them into pipelines, and executing workloads in the cloud on EC2 with S3-backed storage. This was my capstone project for Bachelor's degree. It was awarded a perfect score.

EC2 Scheduler

Cost-optimization tool for Hilton

Lambda and S3 based scheduler that starts and stops EC2 instances based on user-defined windows to reduce non-prod compute costs.

Cloud Engineering Intern

Hilton

Jun 2024 — Jun 2025

Built internal automation tooling for AWS environments, including EC2 cost-optimization, observability integrations, and infra-as-code workflows.

Utilized Boto3 to develop an API that provided temporary AWS credentials via Ping Federate and a SAML assertion
Built a Python-based automation tool that tracks and versions project releases across environments, integrating with Datadog and Confluence for end-to-end visibility
Created a Terraform-managed EC2 scheduler with Lambda and S3 to automate instance uptime to cut EC2 costs
Developed and managed diverse range of services utilizing terraform, while keeping IaC clean and modular

Research Assistant

Tufts University

Summer 2023

Supported research projects with data processing and scripting abilities

Created an image analysis application that could perform operations on two images to create a redoxed output
Manipulated data through NumPy, normalized and correlated large matrices of data
Created a GUI using PyQT6 that allowed .TIF rendering within frame

HackHarvard, HackBrown & SBUHack Winner

Hackathons

2022 — 2023

Built award-winning full-stack systems across AI, hardware, IoT, and backend automation—delivering production-style prototypes under 24–36 hour deadlines.

Developed Steno (HackBrown Winner), an AI-powered meeting assistant using Whisper + GPT-3 for real-time transcription, multi-session summarization, and a Python/Flask API integrated with a live Discord voice listener.
Built Xeri (SBUHack Winner), a custom therapeutic input glove using ESP32, analog sensors, and gyroscope data to translate fine-motor hand movements into computer commands—focused on accessibility and low-cost rehabilitation.
Created HomeNet (HackHarvard Winner), a modular IoT home-automation system with facial recognition, voice command detection, an optimized Python hub server, and a device SDK enabling new IoT devices in ~10 lines of code.
Worked on backend architecture, hardware integration, and API development across all projects, rapidly learning new frameworks (OpenCV, hardware libraries, AngularJS, Whisper) under tight time constraints.

About

Cloud engineer with a CS degree and math minor. I build tools that make cloud infrastructure easier to work with. Most of my time goes into automation, Terraform, and writing code that other engineers won't hate me for.

Go + AWS + Terraform is my usual stack. I care about good logging and pipelines that actually work. Sometimes I build frontends too, like this site.

outside work

I lift regularly and play volleyball when I can find a court. Big reader of history, especially ancient Greek and Roman. Dual U.S.–Greek citizen, so I spend time around the Mediterranean when possible. The photo is from Samothrace.

I also write small scripts and tools for fun. Automating random stuff is basically a hobby at this point.
