- Mapped requirements and drafted BPMN process workflows for a commercial appraisal platform.
- Built a mobile CRM for motorcycle rental shops in Vietnam using Flutter and Firebase, replacing paper logs.
- Built a script to extract 15,000+ address records by inspecting web traffic and mapping an undocumented API with DevTools.
- Wrote a Python tool connecting Siemens TIA Portal to Google Sheets, letting colleagues run PLC automated test cases directly from a spreadsheet.
- Contributing to open-source Web3 projects, protocol adapters, and tooling to verify on-chain state.
Evgenii Zinner
Full-Stack Engineer & Troubleshooter
Engineer
Maintained telecom infrastructure, then moved into industrial automation—building HMI dispatch screens, tracing packet bugs with Wireshark, and digging into legacy source code to build firmware repair tools.
Manager
Managed an industrial automation branch during COVID supply crunches, bringing in clients stuck without Siemens hardware and migrating them to domestic controllers. Later built out a physical coworking space from renovation to daily operations.
Now
Full-stack engineer and troubleshooter. Continuously mastering modern tools and technologies, solving practical engineering challenges, and building dependable, high-leverage software.
Diagnostics & State Failures
Tracing broken logic, silent packet drops, state corruption, memory leaks, and undocumented APIs where standard answers fail.
Edge & Serverless
Cloudflare Workers, D1 SQLite, KV, WebSocket and webhook pipelines, RESTful backends, and low-latency distributed state.
Autonomous Agents
Multi-agent orchestration, automated code generation, and validation loops using Jules API, Google AI Studio, and Antigravity CLI.
Languages & Runtimes
TypeScript, JavaScript, Dart, Python, Bash / Shell, SQL. Quick to internalize and operate in new language ecosystems.
Experience
- Launched and operated an independent coworking space: did hands-on physical buildout from empty premises to opening day.
- Evaluated and configured existing booking, access, and CRM tools to automate reservations and prevent double-bookings.
- Managed daily operations and budgets, and trained front-desk staff.
- Worked with freelance content creators for Instagram to build local presence and attract members.
- Managed branch operations and a team of two, coordinating equipment deliveries, technical support, and contracts.
- When COVID disrupted European hardware supplies, migrated client systems to domestic controllers so production didn’t stall.
- Handled contract negotiations, resolved supplier delays, and kept key industrial accounts running during pandemic shortages.
- Built an in-house flashing tool cutting controller repairs to minutes, and resolved legacy UDP/TCP socket drops with Wireshark to prevent production line downtime.
- Engineered HMI dispatch screens with real-time telemetry, eliminated sensor database bloat, and maintained office servers and network switches.
- Installed and configured enterprise PBX/VOIP systems, server racks, and network switches across client sites—testing optical/copper lines and maintaining rack topology.
