Goal: Build a full recruitment platform from scratch that automates the entire hiring pipeline, from candidate sourcing through to placement and invoicing, replacing manual processes with AI-driven workflows.
Outcome: A production SaaS platform serving 300,000+ users, running 24/7 with 99.9% uptime. Thousands of automated processes orchestrated across the platform handle everything from candidate matching and outreach to compliance checks, CRM synchronisation, content publishing and financial reporting. Reduced time-to-shortlist by over 80% and replaced three separate tools (CRM, finance, communications) with a single integrated system.
AI Candidate Matching
Recruiters were manually reviewing hundreds of CVs per role. Built a multi-dimensional matching engine that scores candidates across salary, location, seniority, skills and availability, then auto-grades and ranks them. Cut shortlisting time from days to minutes.
CV Processing & Anonymisation
Hiring bias was affecting candidate outcomes. Built an automated anonymisation pipeline that strips identifying information from CVs, replacing real names, companies and universities with generic labels to enable blind screening. Processes CVs in seconds with no manual intervention.
Email & Campaign Automation
The team was sending outreach manually, one email at a time. Built a multi-channel campaign engine covering email, SMS and WhatsApp with personalisation, scheduling and deduplication. Thousands of targeted communications go out weekly with full delivery tracking.
Ada: Conversational AI Recruiter
Candidate engagement was bottlenecked by human availability. Built an autonomous AI recruiter that handles onboarding conversations, collects video introductions, negotiates salary expectations and manages data requests across email, SMS and Slack. Runs 24/7 without human input.
Performance & Gamification
Needed to drive measurable performance across recruitment teams and candidates. Built league tables, progression systems, KPI dashboards and goal tracking into every surface. Team and individual performance is visible in real time, driving accountability and competitive output.
HR Operations & Compliance
Candidate onboarding involved manual checklists and compliance gaps. Automated the full pipeline: multi-step onboarding, right-to-work verification, video screening, GDPR-compliant data erasure, and live CRM synchronisation. Compliance is enforced by the system, not by people remembering.
Finance Hub & Analytics
Finance was scattered across spreadsheets and manual tracking. Built a full invoicing, commission and P&L system with automated PDF generation, payment collection, placement tracking and team commission splits. Replaced the need for a separate finance tool entirely.
Enterprise Security
A platform handling sensitive candidate data needed production-grade security from day one. Implemented 2FA, role-based access control, OWASP Top 10 compliance, automated bot detection, rate limiting and real-time error monitoring. Enterprise-grade security, built and maintained by one engineer.
SEO & Generative Engine Optimisation
Organic traffic was near zero with no search visibility. Built a full SEO and GEO strategy: structured data (JSON-LD) for job postings, server-rendered pages for crawlability, automated sitemap generation, Google Indexing API integration, and content optimisation for AI search engines. Drove job listing impressions towards a 1M/month target.
R&D Innovation
OHUB's matching engine required solving problems where no off-the-shelf solution existed. Novel approaches to constraint extraction and entity resolution were engineered from first principles, qualifying for HMRC R&D tax relief. The platform scores candidates across seniority, salary trajectory, geographic constraints and clearance requirements simultaneously, something no existing recruitment tool offered.
