Last position:
Fullstack Developer at PLANT-MY-TREE
PLANT-MY-TREE®-per-order
The application enables Shopify merchants to automatically place tree-planting orders for every incoming order. By integrating ecological contributions directly into the purchase process, the manual effort for tracking and billing reforestation initiatives is eliminated. The system increases transparency for end customers through real-time visualizations of the ecological impact directly in the storefront. The architecture is based on a modular monolith with Spring Boot in the backend and an integrated React app inside the Shopify admin area. The solution uses webhooks to capture order data in an event-driven way and integrates the weclapp ERP system for automated monthly invoicing. An app proxy mechanism provides dynamic statistics such as CO2 compensation and planted trees without any performance loss for the merchant shop.
Tasks:
- Design of the modular software architecture based on Spring Modulith to ensure high maintainability
- Development of the event-driven business logic for evaluating Shopify orders via webhooks
- Implementation of automated invoicing by connecting the weclapp REST API
- Building the frontend using React Router and Shopify App Bridge for native integration
- Design of the database model and implementation of the persistence layer with JPA/Hibernate and Prisma
- Integration of internationalization processes for global use in the frontend and email communication
- Automation of deployment processes using Docker and GitLab CI/CD
Project skills: Java 25, Spring Boot, Spring Security, Spring Modulith, Hibernate, JPA, REST API, PostgreSQL, Maven, Liquibase, React, TypeScript, React Router, Vite, Node.js, Prisma, Zod, Docker, Docker Compose, GitLab CI/CD, Shopify CLI, Shopify App Bridge, Polaris, weclapp, i18next, Lombok, Vitest

About the technology
Async Rust runtime
Tokio is the async runtime most Rust teams use to handle concurrent work without blocking threads. It powers services that need fast I/O, low latency, and careful resource use. Companies bring in Tokio specialists when they need stable async code, not just working code.
What it builds
- Network services and APIs
- Background workers and schedulers
- Message-driven systems and stream processors
- Gateways, proxies, and other I/O-heavy services
Tokio fits backend products that spend their time waiting on sockets, files, queues, or timers. It is also common in Rust systems that must stay responsive under load.
Core ecosystem
Tokio often appears with tokio::spawn, channels, timers, TCP and UDP sockets, and async file I/O. Strong specialists also know how it works with libraries like Axum, Hyper, Tower, and tracing. They choose the right runtime pieces for the workload instead of forcing a one-size-fits-all setup.
When to bring in help
Companies usually look for Tokio expertise when a Rust service becomes hard to tune, tasks pile up, or async code starts mixing with blocking work. It also helps when a team is moving from synchronous Rust to async Rust and needs a clean structure. In Germany, this is common in product teams that want remote support while keeping technical discussions in English.
What strong specialists do
- Separate blocking and non-blocking work clearly
- Design task flows, channels, and cancellation paths
- Prevent deadlocks, starvation, and noisy retries
- Add observability with logs, metrics, and traces
Good Tokio professionals write code that stays predictable under pressure. They reason about runtime behavior, backpressure, and failure handling, not only API design.
Review and handover
A solid Tokio engagement ends with readable async boundaries, tests around tricky timing, and clear notes on runtime choices. That makes it easier for the next Rust specialist to extend the service without re-learning the architecture. It also reduces the risk of hidden blocking calls and brittle concurrency.
Frequently asked questions
Key details about Tokio, drawn from the questions we get asked most.
Tokio is used to build async Rust systems that do network and I/O work efficiently. Teams use it for APIs, workers, gateways, and services that must handle many tasks at once without blocking. It is a strong fit when concurrency matters more than raw single-thread logic.
Tokio is the most common choice when a Rust project needs a mature async runtime and a broad ecosystem. Compared with async-std, it is often preferred for server work, networking, and library support. Compared with plain threads, it gives finer control over I/O-heavy workloads and task scheduling.
A strong Tokio specialist usually knows async Rust well, including Future, Send, lifetimes, and ownership in concurrent code. Useful adjacent tools are Axum or Hyper for web services, Tower for middleware, and tracing for observability. Familiarity with testing timing-sensitive code is also valuable.
A small internal service may only need a Tokio expert for a focused review or a short implementation task. A production system with many async boundaries, message queues, or network protocols usually needs deeper experience. The harder the concurrency and error handling, the more valuable a specialist becomes.
Bring in a Tokio freelancer when the team needs focused help on async architecture, performance tuning, or a difficult bug. It is also useful when the in-house team knows Rust but has limited experience with runtime behavior and cancellation. Short engagements work well for reviews, refactors, and delivery spikes.
Yes, Tokio work fits remote collaboration well because most of the discussion is about code, tests, and system behavior. For teams in Germany, remote support is common, while workshops or handover sessions can happen on-site if needed. English is often enough for technical delivery, especially in mixed teams.
Look for someone who can explain why a task should run on the runtime, when blocking work must be isolated, and how backpressure is handled. A good Tokio specialist writes clear async boundaries, adds tests for timing issues, and uses tracing or logs to make problems visible. Clean failure handling matters as much as speed.
Typical outputs from a Tokio engagement include async service code, refactored task orchestration, reviews of blocking calls, and guidance on runtime setup. You should also expect notes that explain the chosen patterns and any risks left for later work. That makes the codebase easier to maintain after handover.
