Custom business tools that
actually work

I design and build production software tailored to your business — custom internal tools, workflow automation, and AI integration. No templates, no throwaway prototypes. Systems your teams actually adopt — shipped in weeks, not quarters.

Use Cases

Solutions for your
real problems

Whether you need AI-powered automation or a custom business tool — I build what your team actually needs.

Data · Research
Turn Research Into Decisions
Your team spends hours gathering data from scattered sources and still can't tell what's missing. I build systems that automate research, score data completeness, and surface gaps — so you make decisions with confidence, not guesswork.

Custom Tools for Your Business
Off-the-shelf software doesn't fit your workflow. I build tailored tools — financial calculators, collaboration platforms, asset managers, operational dashboards — designed around how your team actually works.

Content at Scale Without Losing Quality
You need to produce, translate, or manage content across languages and formats — but manual processes don't scale. I build AI-assisted pipelines with human oversight, so quality stays high as volume grows.

Automate the Workflow, Not Just the Task
One-off scripts break. I build coordinated automation systems where each step validates the last — with full traceability so your team can trust the output and intervene when needed.

Editorial Intelligence Platform

A publishing team needed structured research content across hundreds of entities in multiple languages. Manual process: 4+ hours per article. Now: under 45 minutes with higher consistency.

  • Replaced a 4-hour manual research process with automated, source-cited intelligence gathering
  • Quantified data completeness for the first time — team sees exactly what's missing across 500+ entities
  • Full audit trail on every data point — critical for editorial credibility
  • Platform keeps working even when AI services go down — no single point of failure

6 modules, 1 platform

Multi-Module Business Platform

A fast-growing brand needed rock-solid tools for their entire operation — financial modelling, design collaboration, media management, and AI-assisted content. 6 integrated modules, one platform, running in production.

  • Custom financial calculator — pricing, margins, break-even, multi-channel sales modelling
  • AI design studio — extracts design DNA from references, generates blueprints, renders photorealistic variations with natural language refinement
  • AI-powered knowledge base with writing assistance — cut content production time by 60%+
  • Full observability across all modules — usage analytics, cost tracking, performance monitoring

Before / After

Editorial Intelligence

Producing structured research content for a 500-entity knowledge base.

Before
Manual process
~0hours / article
  • Manual research across dozens of sources
  • Copy-paste into documents, inconsistent formatting
  • No way to measure data completeness
  • Translation outsourced, weeks of delay
After
Integrated AI workflow
~0min / article
  • Automated research pulls from a synced knowledge base — no more tab-switching across dozens of sources
  • AI-assisted drafting with built-in writing, editing, and translation — one interface, not five
  • Automated completeness scoring tells you exactly what's missing before you publish
  • Same-pipeline translation — minutes instead of weeks of outsourced delay

AI Design Studio

From weeks of external designer back-and-forth to same-day AI-assisted iteration.

Before
External design agency
~0weeks / design cycle
  • External designers with multi-day feedback loops
  • Expensive per-revision pricing — teams hesitate to iterate
  • Vision gets lost in translation between briefs and deliverables
  • No connection to brand guidelines or existing design assets
After
AI-assisted in-house
~0day / design cycle
  • AI extracts design DNA from reference images and generates production-ready variations
  • Natural language refinement — "make the dial darker" — no design skills needed
  • Every output grounded in your brand guidelines via connected knowledge base
  • Unlimited iterations at fixed cost — experiment freely

Process

A clear process,
predictable results

No surprises. Here's exactly how we go from problem to production.

1
Discovery
I audit your actual workflows — not what the org chart says. Bottlenecks, manual steps, integration gaps. You get clarity before a single line of code.
Process map + opportunity report
2
Prototype
A working proof-of-concept on real data, tested with your team. Not a slide deck. Not a mockup. Software you can click.
Functional POC + validation report
3
Deployment
Production integration — APIs, auth, monitoring, error handling, documentation. Built to run, not to demo.
Production system + runbook
4
Optimisation
Metrics tell the story. I track KPIs, tune performance, and train your team until the system runs without me.
KPI dashboard + knowledge transfer
About
Portrait of Benjamin, senior freelance engineer
>

Senior engineer, not an agency.

15+ years of software engineering, from startups to enterprise. I don't sell shiny demos — I deliver systems that run in production, with security, monitoring, documentation, and audit trails.

My approach: understand your business first, choose the technology second. AI isn't an end in itself — it's a lever when well-integrated into your existing workflows and tools.

Recent work: a 6-module business platform spanning financial modelling, design collaboration, media management, and AI-powered editorial workflows — all running in production. Whether the solution needs AI or not, I ship tools that teams rely on daily.

FAQ

Common questions

Custom business tools, AI-powered workflow automation, internal platforms, and data pipelines. If your team has a process that doesn't scale or software that doesn't fit, I build the solution from scratch — designed around how you actually work.

No. AI is a powerful lever when it fits, but many of the tools I build don't use AI at all — financial calculators, collaboration platforms, operational dashboards. I choose the technology that solves the problem, not the other way around.

Four phases: Discovery (audit processes, define KPIs), Prototype (working POC validated with your team), Deployment (integration, security, monitoring), and Optimisation (metrics tracking, adjustments, training). You get a free initial analysis before any commitment.

It means the software ships with security hardening, monitoring, documentation, error handling, and audit trails. No throwaway prototypes — systems your teams can rely on daily, with resilience built in from day one.

Primarily TypeScript, Next.js, React, Node.js, and Python for AI/ML workflows. Databases include PostgreSQL, SQLite, and Redis. But the stack is always chosen to fit the problem — not the other way around.
