Services

Ten directions across three tiers. All grounded in durable, maintainable software.

Core architecture & build

01

Architecture review

Independent audit of an existing system. Deliverable: a written report with prioritised risks and concrete refactor paths.

  • Top 5 architectural risks identified
  • Concrete, actionable refactor plans
  • Effort estimate per direction
Start an audit →
02

Greenfield architecture & stack selection

System design for new products: technology choices, naming conventions, build-pipeline scaffolding.

  • Justified stack decision
  • Module boundaries and responsibilities
  • Build and deploy pipeline draft
Start planning →
03

Full-stack development

Node.js, Hapi.js, MongoDB, Elasticsearch, Google Cloud, and a deliberately framework-free front end. Mid-to-long engagements only.

  • Maintainable, well-documented code
  • Smooth integration into mixed teams
  • Code-quality audits in flight
Get in touch →
04

Cloud & DevOps

Primarily Google Cloud (Cloud Functions, GCS, Firebase, Cloud SQL, Pub/Sub). AWS familiarity (Aurora, DynamoDB) for migration scenarios.

  • GCP-native architecture draft
  • Cost-optimised infrastructure
  • Migration strategy when needed

Specialist domains

05

AI-agentic enablement

Adopt AI coding agents without trading away maintainability. I structure codebases so agents work effectively, build the guardrails that keep their output reviewable, and keep a human hands-on at the keyboard - assisted coding, not vibe coding.

  • Codebase structured for effective agent use
  • Guardrails for maintainable, reviewable AI output
  • An AI-assisted, quality-first team workflow

06

IoT / sensor & hardware-software systems

Hardware-software integration and sensor/IoT data pipelines, backed by a dual computer-science and mechanical-engineering foundation. Industrial monitoring, wireless sensor networks, digital signage.

  • Reliable device-to-cloud data pipelines
  • Hardware/software integration that holds up in the field
  • Architecture for variable, high-volume sensor data

07

Geo / mapping systems

Map-centric web apps and location search across Google, Bing, and Mapbox, with high-performance geo-clustering for large datasets. Built for proptech, logistics, and anything that lives on a map.

  • Fast map UIs over large datasets
  • Geo-clustering and spatial search
  • A provider-agnostic mapping layer
Map it out →
08

Performance & scale rescue

Diagnose and fix systems that have slowed to a crawl or stalled in delivery. Track record: search times cut by an order of magnitude, and a flagship product stuck for years shipped in weeks.

  • Root-cause diagnosis of the real bottleneck
  • Order-of-magnitude performance gains where they exist
  • A stalled delivery unblocked
Get unstuck →

Advisory & people

09

Code review & mentoring

Code-quality audits; one-on-one or team mentoring; SDLC + Agile process coaching.

  • Concrete code-review report with action items
  • Faster junior/mid-level developer growth
  • Team-level best-practices document
Start mentoring →
10

Fractional CTO / advisory

Recurring sessions for founders and technical leads who need senior input - without a full-time CTO hire.

  • Weekly or biweekly cadence
  • Strategy, hiring, technical decisions
  • Independent, honest opinion
Start advisory →
