Engineering the systems
behind great software

I'm Nehemiah I build scalable backend systems and the platforms that run them. From APIs and distributed services to CI/CD, infrastructure, and observability, I engineer systems designed for reliability, performance, and scale.

Backend Designing scalable APIs and distributed services
Platform Building tooling and infrastructure that accelerates development
Cloud Automating deployments and operating reliable production systems

Forge

Integrity

A self-hosted CI/CD platform and artifact registry that provides a secure, reproducible software delivery pipeline. By combining kernel-level build isolation, deterministic dependency resolution, and semantic versioned artifacts, it protects the software supply chain against compromised build environments, dependency tampering, and package spoofing while ensuring reproducible builds.

ObserveX

Visibility

An enterprise-grade observability platform built on the LGTM stack that unifies metrics, logs, and traces into a single reliability workflow. It replaces fragmented monitoring with a self-service framework for SLO management, DORA analytics, and automated error budget alerting, enabling engineering teams to detect regressions, measure service health, and improve software delivery with confidence.

SwiftDeploy

Automation

A policy-driven, declarative deployment engine and CLI that generates runtime configurations, orchestrates container deployments, and enforces automated safety gates using Open Policy Agent (OPA) and Prometheus metrics. By treating a single YAML manifest as the source of truth, it eliminates configuration drift and prevents unsafe deployments through automated pre-deployment and promotion policy enforcement.

RBAC System

Security

An enterprise-grade identity platform providing secure authentication, role-based authorization, and asynchronous background processing. It combines rotating short-lived tokens, automated brute-force protection, and zero-disk memory streaming to harden application security, while moving email delivery and media processing off the HTTP request path to reduce latency and improve system throughput.

EnergyIQ

  • Designed, built, and operate CI/CD pipelines that automate software delivery, enabling reliable and repeatable deployments.
  • Reduced CI/CD pipeline execution time by 40% through dependency caching, parallel job execution, and elimination of redundant workflow stages.
  • Migrated manually provisioned AWS infrastructure to reusable Terraform modules, establishing version-controlled, reproducible infrastructure provisioning
  • Designed and implemented an observability platform introducing SLOs, SLIs, and error budgets to guide reliability engineering.
  • Standardized deployment runbooks, operational documentation, and incident response procedures

Why Your Kubernetes Readiness Probes Are Lying to You

A deep dive into the subtle misconfiguration that silently routes traffic to pods that aren't ready — and how to fix it properly.

GitOps Is Not a Deployment Strategy — It's a Discipline

The difference between teams that adopt ArgoCD as a tool and teams that actually practice GitOps. Spoiler: it's mostly cultural.

The Runbook Is a Love Letter to Your 3am Self

How I learned to write runbooks that actually help during incidents, not just check a compliance box.
