Backend & Systems Engineer  ·  Founding Engineer @ Nover

About

"I build the unglamorous half of a product."

Backend & Systems Engineer. Final-year Electrical Engineering — Electronics & Communications student at Alexandria University, building production infrastructure now instead of waiting on graduation.

The APIs nobody sees. The queues that don't drop messages. The GPU pipelines that don't fall over at 3am. The schemas that survive the next migration. Production engineering and DevOps are where I'm strongest — AI infra, robotics, and embedded all lean on the same systems instincts.

Frontend isn't my specialty. I can put a working UI over my own APIs, but pair me with a real frontend engineer for anything design-heavy.

Where I've Been

Today — Founding Engineer & Tech Lead at Nover. I own the production backend for our AI image generation platform: fine-tuning diffusion models on H100s, serving inference through ComfyUI on AWS, and wiring it together with a custom WebSocket API that holds up under real traffic. Pre-seed in progress.

Recently — Software Engineer at RankUp (EU, remote). Built the topical map update system — an automated keyword research → clustering pipeline using SBERT embeddings and DataForSEO. Backend-and-data work, end to end.

Before — 1.5 years as a Software Engineer at a US neuromodulation research company. Built a real-time EEG digital twin pipeline: streaming brainwave data off OpenBCI hardware, running Hilbert transforms on the wire, and feeding it into coupled oscillator models. Authored a research paper on Kuramoto-based EEG synchronization along the way.

On the side — Led Mind Cloud (70+ engineers) from a 9th-place ERC finish to 2nd and 3rd at UGVC, and migrated the entire stack to ROS 2 — a distributed systems problem dressed up as a robotics one.


Core Stack — Backend & Systems

This is what I reach for first, and where most of my production work lives. Hover any icon for a tooltip.

Backend & APIs

FastAPI Django Flask Spring Boot Node.js Express.js GraphQL gRPC WebSockets REST

Patterns I ship: REST · gRPC · WebSocket systems · long-lived streaming connections · idempotent task APIs.

Distributed Systems & Architecture

Redis Apache Kafka PostgreSQL MongoDB Apache Cassandra Apache Flink Apache Airflow RabbitMQ

Architecture focus: microservices · event-driven backends · queue-based workloads · atomic task distribution · real-time stream processing · ETL pipelines · structured logging.

Production Engineering & DevOps

AWS Docker Kubernetes Terraform GitHub Actions Nginx Linux Bash Prometheus Grafana Cloudflare

What I actually do in production:

  • Cloud architecture on AWS — ECS, S3, RDS, GPU instances for inference
  • Container orchestration and reproducible Docker / Kubernetes pipelines
  • Infrastructure-as-code with Terraform — repeatable, reviewable, rollback-friendly
  • CI/CD with GitHub Actions — build, test, deploy, with rollback discipline
  • Observability with Prometheus + Grafana — live dashboards, alerts, real traffic visibility
  • GPU-backed service operation (H100s for diffusion) — cost, throughput, failure recovery
  • Linux administration, shell tooling, and the boring glue that keeps systems alive

Languages I Reach For

Python Go Rust TypeScript JavaScript C++ C Java MATLAB Bash

Tools & Editors

Git GitHub Vim VS Code


Supporting Stack

I lean on these when the system needs them — not the headline, but I've shipped real things with each.

AI Engineering & MLOps — diffusion models, GPU inference, LoRA fine-tuning

PyTorch TensorFlow scikit-learn CUDA Hugging Face Modal ComfyUI LangChain

Treated as an infrastructure problem: model deployment, inference serving, GPU workloads, visual generation systems.

Frontend (basic — not my specialty) — enough to put a working UI over my own APIs

HTML5 CSS3 Next.js React Tailwind CSS

Honest about scope: I can ship a usable Next.js / React surface over an API I built, but I'm not a frontend engineer. For anything design-heavy, polished, or accessibility-critical, pair me with someone who specializes in it. Backend is where I optimize.

Robotics & Embedded Systems — SLAM, autonomous navigation, low-level I/O

Arduino Raspberry Pi C++ ROS 2 ESP8266 Embedded C

SLAM · autonomous navigation · LiDAR perception · robot control · TF2 · UART · I2C.

Numerical & Analytics — when data needs shape before it ships

MATLAB Pandas NumPy SciPy

Analytics workflows, DataForSEO integrations, signal processing for the EEG pipeline.
