Most software teams don't fail at the code. They go quiet halfway through, miss the date they committed to, and hand over something that breaks the first week it meets real users. Eleven years on this platform. 100% on time. 100% on budget. Preferred Freelancer. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHAT WE BUILD ▪️...Most software teams don't fail at the code. They go quiet halfway through, miss the date they committed to, and hand over something that breaks the first week it meets real users. Eleven years on this platform. 100% on time. 100% on budget. Preferred Freelancer. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHAT WE BUILD ▪️ AI AGENTS AND LLM SYSTEMS IN PRODUCTION RAG assistants over private document sets, scoring and classification engines, voice systems. OpenAI, Claude, LangChain, vector databases. Working systems with real users behind them, not demos. ▪️ OPERATIONS DASHBOARDS FROM MESSY DATA A nightly SFTP file drop turned into a live call-centre leaderboard. Two live dashboards on the ServiceTitan API pulling job and campaign data for home-services contractors. Real-time panels nobody has to rebuild by hand. ▪️ COMMISSION, PAYROLL AND PAYOUT ENGINES A broker commission and HR platform with multi-tier splits. An automated payroll system that replaced manual reporting. Here the business rules are the build — clawbacks, mid-month leavers, tiered splits, the edge cases nobody wrote down. ▪️ SAAS PLATFORMS TAKEN TO PRODUCTION Next.js, Node, Python, Postgres, Supabase, Stripe. Security review, documentation, staged delivery. Our most recent client on this platform wrote: "worked through the project in stages, accommodating various customisations and changes as the project developed." ▪️ WORKFLOW AND API INTEGRATION Connecting systems a business already runs — CRMs, funder portals, payment providers, third-party APIs. Automation that lives in code you own, not a no-code tool you rent. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ HOW WE WORK ✅ Milestones, always. Funded before work starts. ✅ Weekly demos on anything substantial — you watch it run, you don't read about it. ✅ Scope in writing, re-confirmed at every milestone. ✅ A change is a new milestone, never a silent absorb. If you have a process someone rebuilds by hand every week, or two systems that should talk to each other and don't, that's the conversation worth having. less
