Doug Silkstone - Full-Stack Engineering

Doug Silkstone is a British full-stack engineer and three-time exit founder operating as a solo consultant from Prague, Czech Republic. He works on greenfield projects and early-stage startups, handling everything from research and design through engineering, growth, and team building. His track record includes 81 products launched, over $20M raised by clients, and more than 1 billion product sessions across his work. He's rated 5.0 on Clutch (verified) and holds a Top 1% ranking on Contra.

Services and capabilities

Silkstone offers full-stack engineering across web, mobile, and desktop platforms. His work spans interface design, AI systems integration, real-time data pipelines, reinforcement learning, growth and acquisition strategy, analytics, and founder mentorship. He's worked with generative AI tools including Anthropic's Claude Code and OpenRouter, and builds production systems in TypeScript, React, Node.js, Python, C, and Rust. Recent projects show depth in niche areas: he built a real-time telemetry system for sim racing (PitGPT for iRacing and ACC), a live data visualization tool for Bungie's Marathon shooter, and a reinforcement learning lab for Counter-Strike 2 bots. He also developed a Chrome extension for Contra that crowdsourced five million job opportunities and reached #1 Product of the Day on Product Hunt without scraping infrastructure.

Beyond individual features, Silkstone takes on 0-to-1 product launches. He built a social casino game studio from zero to one million players in ninety days using React and TypeScript, and shipped a community dining platform (Dinners with Friends) with event listings, venue partnerships, and booking in Next.js. He's designed conversational AI chat interfaces for lead generation matching companies to enterprise solutions, and built serverless video pipelines that process recordings into captioned, auto-cut clips in twenty seconds using WebCodecs and LLM-driven editing.

Notable work

Clients span gaming, fintech, e-commerce, and media. For Bungie, he created live shot-and-death telemetry visualization for the Marathon game. For Contra, he developed the Chrome extension that fed five million opportunities into their freelancer marketplace. He worked with Sky, Groupon, The Motley Fool, MIT, and Reach Robotics. His work includes VoucherCloud's programmatic PPC system (which helped lead to a Groupon acquisition), a benchmarking report analyzing the UK's top 200 e-commerce brands in a four-week sprint, and a solution that recovered 15% average margin across 500+ stores by stopping discount extensions from hijacking checkout flows.

He's also contributed to MIT's GenAI research and built educational products: an eight-week LLM course interface that received an Awwwards Honorable Mention, and Helix.ai, a landing page for an LLM research lab using cinematic scroll and data-driven animations.

How they work

Silkstone operates as a solo consultant available for "open slots" booked via calendar. He replies within a day to inquiries and offers quick chats or full project briefs. His website includes an OpenAPI endpoint (/.well-known/agent.json) for AI agents to fetch project briefs and plan handoffs. Engagement is direct—email preferred and typically answered same day. There is no mention of fixed pricing; engagements appear to be negotiated per project.

Team and credentials

This is a solo operation: one engineer with three prior exits. Silkstone holds verified 5.0-star ratings on both Clutch and Contra (Top 1%). He's a MIT GenAI contributor. No formal certifications (ISO, SOC 2) are mentioned. His technology affiliations include Google Cloud and Cloudflare infrastructure.
