Architecture and execution of the largest Irish public-sector CMS migration to date: 200,000+ pages, multi-department editorial workflows, structured content models, zero-downtime cutover. Now serving Irish citizens with sub-200ms responses at scale.
Client-side generator with entropy display, ambiguous-character exclusion, and a visual strength meter. Nothing leaves your browser.
Format, validate, minify JSON in-browser with syntax-highlighted output, clear error reporting, and character/line stats.
Live regex testing with capture-group breakdown, flag toggles (g, i, m, s, u), and a built-in cheat sheet.
Decode JWTs in-browser. Parses header, payload, and signature with human-readable timestamps and expiry badges.
Encode/decode text or binary data. URL-safe mode, file input, entirely client-side.
Cryptographically secure SECRET_KEY values for Django settings. Configurable, with ready-to-use code snippets.
Redis backend setup, per-view + template fragment caching, the low-level API, ORM patterns, invalidation, and stampede protection — every layer covered.
Move beyond bolt-on AI. Design Django apps where intelligence is a load-bearing layer — async queues, token budgets, prompt registries, RAG, model routing, human-in-the-loop.
Fast code isn't always green code. Measure CPU energy with pyRAPL, track CO₂ with CodeCarbon, fix the Django patterns silently burning the most power.
Lazy imports, frozendict, comprehension unpacking, Tachyon profiler, sentinel type — everything landing in Python 3.15.
Hardware costs, labour savings, hidden costs, and a Python break-even calculator. Honest look at when ag robots pay for themselves.
GPS waypoint missions over MQTT, TFLite weed detection on Pi, variable-rate sprayer control, nightly Claude crop advisor.
LLM mental models, token arithmetic, prompts, structured output, tool use, embeddings, RAG, streaming, production patterns.
342 US occupations scored for AI exposure by an LLM pipeline. What the data says about software devs, and how to build the scoring loop in Python.
Extend the Wagtail admin with snippets, SnippetViewSet, custom menu items, admin views, lifecycle hooks, dashboard panels.

Most recently at GlobalLogic, I led the migration of a 200,000+ page public-sector website to Wagtail CMS. I work across the full lifecycle: architecture, APIs, CMS platforms, CI/CD, and team mentorship.
I loved working with Rizwan at DIT. His skills and professionalism as a smart, self-organising, focused developer were matched by his fantastic team spirit and a kind, patient, modest nature. A great addition to any team.
Riz is an excellent Python developer and problem solver. Experienced in CMS systems and server-side logic. An integral member of my team always keen to offer solutions and take responsibility for a range of challenges.
Rizwan took a leading role on backend development of the SILVA CMS and successfully stepped up as acting manager, showing excellent management skills to meet critical business targets. A popular figure, always professional.
Strong ownership and driving for results all the time. Sees and addresses everything from the big picture to the details. Creative, energetic, solutions-oriented, motivated. An asset to any company.
