Akash Dubey

Linux, DevOps & Blockchain Infrastructure Engineer

I operate production Linux infrastructure and blockchain nodes - validator, RPC, full and archive node fleets across 60+ networks at RapidNode and 16+ networks at InfStones - and build the automation, monitoring and recovery tooling that keeps them running. I am a SysAdmin of ALG (Arka Linux GUI), an Arch-based Linux distribution.

Engineering snapshot

Four areas that show up repeatedly across my work - from a single Linux host to validator fleets and the distribution build pipeline behind them.

/01systems

Linux Infrastructure

Production Linux fleets, services and storage kept healthy and current.

  • Arch, Debian, Ubuntu and RHEL systems
  • systemd service management and package maintenance
  • ext4, Btrfs and LVM storage; filesystem and disk troubleshooting
/02nodes

Blockchain Infrastructure

Validator, operator and RPC infrastructure operated across many networks.

  • Validator & operator nodes, RPC, full, archive and light nodes
  • Ethereum, Cosmos SDK and Solana ecosystems
  • Synchronization, snapshots, pruning, upgrades and recovery
/03operations

DevOps & SRE

Automation and reliability work around the infrastructure.

  • AWS (EC2, ECS, S3), Docker, Ansible, Jenkins and GitHub Actions
  • Bash and Python automation for provisioning, health checks and recovery
  • Monitoring, alerting, incident response, on-call and runbooks
/04community

Open Source

Maintaining Linux distribution and build/release engineering.

  • SysAdmin of ALG (Arka Linux GUI)
  • Arch packaging, PKGBUILDs, repositories and ISO builds
  • Calamares installer configuration and release automation

How I work

01

Automate the repeatable

Node provisioning, health checks and recovery are scripts and services - not manual steps.

02

Observe before changing

Sync state, peer count, resource use and service health are watched before acting.

03

Make it reproducible

Package builds, ISO profiles and repositories are scripted, versioned and repeatable.

04

Keep operations simple

Boring, reliable tooling and clear runbooks beat clever one-off fixes.

02

Experience

Production and open-source roles. Expand an entry for responsibilities and the tools involved.

Blockchain SRE

Featured projects

Two Linux distribution projects I have designed, packaged and shipped - including the build and release infrastructure around them.

01

Open-source Arch-based Linux distribution

ALG - Arka Linux GUI

A maintained Arch Linux distribution with a graphical installer and its own build infrastructure.

SysAdminFeb 2023 – Present

Problem

Arch Linux is powerful but demanding to install and configure. ALG layers a guided installation and a consistent, themed desktop experience on top of Arch.

What I built

  • Maintain Arch packages and PKGBUILDs, keeping the distribution's repositories signed and current.
  • Own ISO builds for the KDE Plasma, XFCE and GNOME editions and the Calamares installer configuration.
  • Maintain Bash build/release tooling and GitHub Actions for package builds, repository database updates and release validation.
  • Test applications and resolve packaging, installation and hardware issues, shipping bug fixes and improvements.

Stack

  • Arch Linux
  • PKGBUILD
  • Bash
  • archiso
  • Calamares
  • GitHub Actions
  • GPG

Open-source Arch-based Linux distribution for college communities

TCET Linux

A distribution forked from ALG and maintained end-to-end, from PKGBUILDs to a signed package repository.

Developer & MaintainerApr 2023 – Sep 2024

Problem

The project needed a Linux distribution students could install and use, with a package repository that avoided manual release work.

What I built

  • Developed and maintained the distribution with XFCE and GNOME editions on a rolling-release model with automated package updates.
  • Managed the signed package repository on GitHub Pages - PKGBUILDs plus Bash automation for version bumps, builds, signing and repository database updates.
  • Built selective and bulk rebuild automation and troubleshot build and repository failures to keep releases reliable.

Open source

Open-source maintenance is a large part of my work. I am a SysAdmin of ALG (Arka Linux GUI) and work across its packaging, build and release tooling.
