I'm Juliano Sig, an AI Engineer focused on agent infrastructure, browser automation and full-stack products. Founder of Shimpz and creator of easi.run.
My work connects the agent to the real application: browser sessions, APIs, permissions, persistent state, files and the interface a person uses to step in. I work across Rust systems, Python backends and TypeScript interfaces, from the underlying service to the product people use.
Self-hosted Chrome sessions for people and AI agents. An open-source project that brings browser control, live viewing and human takeover into one workflow.
| Engineering problem | What I built in easi.run |
|---|---|
| An agent needs to use a real browser | MCP and REST tools, plus optional CDP access for existing automation |
| A login needs a person | Live viewing and control handoff that pauses agent actions |
| Work must survive the next session | Encrypted saved browser profiles and permissions per agent token |
| Browser access needs boundaries | Container separation, restricted network egress and a documented security model |
| People need to see what happened | An action timeline, session recording and replay |
| Remote interaction needs to feel responsive | A Rust compositor and streaming pipeline, with reproducible benchmarks |

In the published headless benchmark, text scrolling used 1,862 kbit/s versus 16,433 kbit/s for KasmVNC, with SSIM of 0.990 versus 0.977. Typing input-to-draw p50 was 28 ms versus 69 ms. These are laboratory measurements from 2026-10-21; the case study includes conditions, missed targets and resource tradeoffs.
| Project | Focus | Stack |
|---|---|---|
| pyhouse | A Python query-building library for ClickHouse, with entities, filters, joins, aggregation and pagination | Python · ClickHouse |
| cryptoarbs-front | Application frontend with authentication, account settings, exchange credentials and subscription screens | SvelteKit · TypeScript · Tailwind CSS |
These repositories show different stages of my work, including experiments and earlier implementations. Read the experience notes → for scope and technical context.
Agent infrastructure — MCP tools, browser runtimes, persistent sessions, human control and API integrations.
Backend & data systems — Python, Django, REST APIs, WebSockets, PostgreSQL, Redis and ClickHouse.
Product & systems engineering — Rust, TypeScript, Svelte, Docker, Linux, CI, technical documentation and interfaces that make complex systems usable.
Alongside open source, my private project work includes data collection, backend services, market-data integrations and payment workflows. I describe that experience without publishing private source code or internal project details.
I'm interested in AI engineering, agent infrastructure and product engineering opportunities. If your team needs someone who can connect the systems work to the user experience, let's talk.
I share what I'm building on X @jul1anodev. Follow along for browser agents, engineering decisions and new releases.
