Staff / Lead Systems & Platform Engineer

Ronny Arvelo

I turn ambiguous, high-stakes engineering problems into reliable production systems. Across fintech, data, and enterprise environments, I combine distributed-systems architecture, hands-on implementation, and cross-team delivery with clear ownership—using agentic workflows when they make execution faster, more consistent, and easier to verify. Based in Buenos Aires, I work fluently in English and native Spanish.

What is VulcanByte?

VulcanByte represents a philosophy of software engineering that marries rigorous foundational systems design with modern, agent-assisted execution. It stands for building resilient distributed infrastructure, maintaining strict quality guardrails, and turning complex constraints into production capability.

  • Resilient Systems Architecture

    Designing distributed, event-driven platforms designed around failure modes, explicit interfaces, and long-term maintainability.

  • Disciplined Agentic Engineering

    Leveraging AI agents, custom skills, and MCP tools within bounded execution workflows, strict human oversight, and automated testing.

  • End-to-End Ownership

    Taking complex engineering initiatives from high-level ambiguity through specification, parallelized build, and verified production delivery.

How I deliver

  1. 01

    Shape the work

    Turn ambiguous goals into an approved specification with explicit constraints, interfaces, conventions, and acceptance criteria.

  2. 02

    Parallelize deliberately

    I’ve used Codex, Claude Code, and GitHub Copilot—alongside Orca and Conductor when orchestration is valuable—to delegate bounded work across subagents and MCP-enabled tools.

  3. 03

    Verify and encode

    Review integrated results against tests, project conventions, and guardrails, then capture reusable guidance in plugins, skills, and AGENTS.md files.

What I bring to the work

  • Systems and platform architecture

    Distributed, event-driven, and integration-heavy systems designed around failure modes, observability, operational constraints, and long-term change.

  • From ambiguity to production

    Discovery, proof of concept, implementation, rollout, and the coordination required to land complex work across team boundaries.

  • Hands-on technical leadership

    Architectural guidance, clear conventions, mentoring, and delivery ownership without stepping away from implementation.

Technical writing

I’m developing practical writing on distributed systems, platform engineering, and agentic delivery. Until the first pieces are ready, Experience is the best place to see the work behind those subjects.
