Frequently Asked Questions from Technical Decision-Makers
Direct, transparent answers regarding governance, code quality, and engineering engagement models.
Why choose a London engineering boutique over a large consultancy like Thoughtworks or Accenture?
Tier-1 consultancies charge £1,200–£2,000/day per junior developer and bill for months of bureaucratic discovery. As a senior-led London engineering boutique, Xharvoc deploys senior systems architects directly to your codebase, operating 40–55% lower blended sprint costs, delivering working software every two weeks with zero junior overhead.
How does Xharvoc protect client intellectual property and code ownership?
We provide 100% intellectual property (IP) assignment upon commercial milestone settlement. All Git repositories, Docker configurations, database schemas, and architectural blueprints belong entirely to your company from day one.
What security and regulatory standards govern your London software development builds?
Our software engineering lifecycle follows ISO/IEC 27001:2022-aligned ISMS controls and operates on Tier-1 SOC 2 Type II certified cloud infrastructure (AWS Frankfurt, Supabase, Cloudflare). For regulated clients, we build under the UK Data Protection Act 2018 (UK GDPR), FCA Open Banking protocols, and NHS DTAC frameworks.
Can your London team conduct on-site discovery and architecture sessions?
Yes. Our senior solutions architects are based in London and conduct on-site discovery workshops, data modeling sessions, and security audits at your offices in the City, Canary Wharf, Mayfair, or our registered office in Covent Garden (WC2H).
