Core developer on Hawke, a cloud-native EV charger management platform delivering real-time monitoring, remote diagnostics, and operational control across a distributed fleet of field devices.

• 01Develop and maintain the platform end to end — React / Next.js and TypeScript on the front, FastAPI / Python and PostgreSQL on the back — streaming live data over persistent WebSocket (OCPP) connections from ~150 field devices across ~21 sites.
• 02Fixed a database bottleneck that had a server pinned at 99% CPU, adding targeted indexes that made the slowest queries up to 70x faster with identical results.
• 03Improved reliability and monitoring: traced a service opening ~5,000 needless database connections an hour and replaced it with proper pooling, and built centralised logging, Grafana dashboards, and recovery tooling behind >99% device uptime.
• 04Led the platform's AI initiative: built an MCP server that lets AI assistants query live fleet, session, and payment data, plus an in-app assistant — with rate limiting and safety guardrails.
• 05Built a Chrome extension that captures page delete and restore events the vendor's own API never exposed, intercepting internal API traffic and reporting it to a Node.js service.
• 06Developed internal warehouse and procurement platforms (Next.js, React, Node.js, Redis, BullMQ in a Turborepo monorepo) for manufacturing, delivery logistics, inventory control, and scheduling.
• 07Delivered the touchscreen interfaces that run on the devices themselves in Flutter, and integrated a new embedded Linux (Yocto) platform.
• 08Automated build, test, and deployment with Docker and GitLab CI/CD, and built a simulator reproducing real device traffic so the full stack can be tested without hardware.
• 09Implemented payment, invoicing, and e-invoicing compliance flows for a multi-country network — contactless payments, pre-authorisation, tax-ID validation against government APIs, and refund and receipt endpoints.

Full-stack and industrial software for 3D-printing hardware — from a cross-platform app to the operation interface driving the machine.

• 01Delivered a cross-platform full-stack application in Flutter, owning major parts of development, testing, and release preparation.
• 02Built an industrial machine-operation interface in Python and GTK for controlling 3D-printing hardware in production-like environments.
• 03Optimized hardware-to-GUI communication for responsiveness and reliability during real-time machine operation.
• 04Supported code quality through reviews, debugging, and maintainable software patterns.

Planning, procurement, and quality-control workflows on large-scale construction projects.

• 01Supported planning, procurement, and QC workflows for large-scale projects.
• 02Used Primavera P6 for scheduling, resource planning, and coordination.
