From Feb 2020
Senior PHP Developer · TCB Hard + Software
Built and maintained PHP applications for a digital media platform, with a focus on product development, reliability and long-term maintenance.
Summary
Full-stack engineer with more than 10 years of commercial PHP experience across the Laravel, Lumen and Symfony ecosystems, including Symfony microframework work. I also build with Vue.js, JavaScript and TypeScript, modernising web products, APIs and databases. I use AI tools across research, implementation and review, and can contribute as a developer or take technical ownership of a team and its architecture.
Experienced in building systems that must operate reliably under real-world constraints: high load, distributed devices, unstable networks, long lifecycle products, and evolving business requirements.
Strong at:
- turning chaotic systems into clean, maintainable architectures
- building developer-friendly platforms and workflows
- leading technical direction without micromanagement
- owning the whole lifecycle: idea → architecture → implementation → production
- integrating security and reliability into architecture from day one
I work across application code, infrastructure and connected devices, and I enjoy learning the tools a problem calls for.
Distributed video platform: Contributed to a distributed media platform spanning applications and connected devices, with a focus on reliable playback and remote operations.

BREADTH THROUGH CONCRETE WORK
My engineering experience, in context
My commercial foundation is PHP and full-stack development. My wider engineering work connects web products with infrastructure, connected devices, local AI tools and specialised applications. The examples below span professional work, independent products and active prototypes.
Commercial foundation
Web products & platform modernisation
More than 10 years of commercial PHP experience across Laravel, Lumen, Symfony and the MediaWiki / BlueSpice ecosystem. Work spans APIs, data models, multi-tenant platforms, Vue interfaces and legacy modernisation.
The connecting skill is working through an existing system, understanding its constraints and improving it across frontend, backend and operations.
Professional platform work
Digital signage & media playback
Developed and maintained digital media products, combining web applications with connected devices.
Focused on reliable operation, usability and long-term support.
Infrastructure & operations
Linux, networks & device lifecycle
Experience with production infrastructure, Linux operations, monitoring, networking and remote support.
Built practical tooling to help teams keep services and devices maintainable.
Developer tooling & integration
Local AI & engineering automation
Developed local AI and developer tools across C++ and Python, including model integration and workflow automation.
AI supports implementation, tests and reviews. Tabula / Punchenko NNL explores experimental language and model workflows; research results remain under evaluation.
Product projects
Commerce, data migration & back offices
Fermershop combines a storefront with operational tools. I worked on the catalog, product data and dependable delivery.
Other commerce work includes the 6 Moments / Shop Jewel storefront and OpenCart extension packaging.
Practical tools
Desktop utilities & browser tools
Desktop utilities built with Rust and Tauri include an Excel workflow tool and a macOS device-management interface.
TidyDrive is an active cross-device prototype; Frequent Tab is a local Chrome extension. Hardware validation of the new TidyDrive flow is ongoing.
Product integration
Telegram, catalogues & business workflows
Rezar combines a Python Telegram bot, a mobile catalogue, search and filtering, vehicle detail pages, enquiry handling and a catalogue administration interface.
The broader project portfolio also covers task marketplaces, family coordination interfaces, video utilities and tattoo-concept workflows. The common theme is taking a specific user task through to an operational product flow.
Device integration
Embedded systems & physical prototyping
Hands-on work with ESP32, ESPHome, Home Assistant, UART, RS-485 and CAN: device integration, firmware configuration, local web controls, OTA workflows and electronics debugging.
Projects connect physical hardware with software interfaces, including air-conditioner integration and climate-control interfaces. Soldering, connector work and 3D-printed enclosure prototyping complement the software work.
Independent projects
Games, interaction & creative production
Neon Crown explores gameplay and world systems with Unreal Engine and C++, including interaction, HUDs, scene integration and build/release tooling. MythicBoost is a Lua-based World of Warcraft add-on with a configurable HUD and gameplay analysis.
Electronic music production as Techno Punch adds composition, sound, artwork and video presentation. These projects show an interest in the full experience a person sees, hears and interacts with.
AI-NATIVE ENGINEERING
Agentic Engineering & AI-Assisted SDLC
I design AI-native engineering workflows where AI agents support the full delivery loop: problem framing, planning, implementation, testing, code review, deployment, monitoring, and support — with human ownership, validation, and production reliability.
Role positioning
- AI-Native Software Architect
- Agentic Engineering Lead
- AI Platform & Automation Engineer
What I build
- Agentic workflows for repeatable engineering and operations
- AI-assisted SDLC loops with review, testing, observability, and rollback
- Tool-using agents connected to APIs, repositories, CI/CD, and internal systems
From requirements to reviewed implementation
- Capture requests in Linear and clarify the requirements.
- Structure tasks and context with Claude.
- Coordinate implementation incrementally across multiple agents.
- Review the result against the original task, identify missing logic and direct the next iteration.
I keep the customer request, task specification and delivered result connected. My contribution includes problem framing, coordination and hands-on review of the implementation.
