signal acquired

Jimrox

Building distributed systems, infrastructure, and the developer tools that sit underneath both.

About

I work across distributed systems engineering, fintech infrastructure, and AI developer tooling. Most of what holds my attention is the same shape of problem wearing different clothes: what happens when a node fails, when a clock drifts, when a signal looks almost right but isn't.

Alongside engineering work with Minas Tech and Minas AI, I'm building Pigra Labs, a database infrastructure and developer platform aimed at African markets, and finishing an MSc thesis on software-defined radio and deep learning-based anomaly detection in LTE signals.

Experience

Pigra Labs · Founder

  • Designing a database infrastructure and developer platform for African markets, evolved from an early Postgres control plane for fintechs into a broader Supabase-style platform
  • Scoping integrations with African payment rails (Paystack, Flutterwave, MTN MoMo) and SMS gateways
  • Positioning around data sovereignty as a core product requirement, not an afterthought

Minas Tech & Minas AI · Engineering

  • Built a customer support and security monitoring system spanning Gmail ingestion, phishing detection, and Bybit API integration, surfaced through a Retool dashboard
  • Shipped Guardian, a crypto exchange account security monitor in Python (CCXT, FastAPI, WebSockets, SQLite) with encrypted key storage and a polling-based diff engine
  • Produced technical and brand deliverables for Minas AI, including a programmatically generated slide deck on AI agents

MSc Thesis · SDR & Deep Learning

  • Researching software-defined radio and deep learning-based anomaly detection for LTE signals
  • Built the capture environment on an RTL-SDR Blog V4 and a PyTorch convolutional autoencoder pipeline for anomaly detection

Projects

dbfailsimactive

Distributed failure simulator

A five-node cluster with a Raft-lite coordinator and pluggable failure scenarios — replica lag, split brain, network partitions, partial failures — for testing distributed systems theory against something that actually breaks.

Database infra for African markets

A developer platform built around a managed Postgres control plane, with local payment rail and SMS gateway integrations and data sovereignty as a first-class concern.

Exchange security monitor

Tracks crypto exchange accounts for suspicious activity with encrypted API key storage and a polling-based diff engine, drawing on prior withdrawal-tracking and phishing monitoring work.

LTE anomaly detection

A convolutional autoencoder pipeline over signal captured with an RTL-SDR Blog V4, learning what a clean LTE signal looks like well enough to flag what isn't.
