# Software Development & AI Services Fixed-price engagements. Measurable ROI in 90 days. Four service lines built around the operations challenges enterprise teams and founders actually face. ## What services does Code and Trust offer? Code and Trust offers four core service lines: AI implementation (replacing manual workflows with AI-powered systems), AI workflow automation (custom pipelines that eliminate data entry), legacy system modernization (zero-downtime migrations to modern code), and custom software development (full-stack apps built to spec). Every engagement is fixed-price with 90-day post-launch support. ## AI Implementation 30–60% cost reduction in 90 days We map your manual workflows, identify where AI creates the highest leverage, and implement the systems — LLM pipelines, RAG systems, AI decision routing — directly into your operations. You see ROI within 90 days or we keep working. - Pre-build workflow audit included on every engagement - LLM pipeline integration (OpenAI, Anthropic, Gemini) - RAG systems over your proprietary data - AI decision routing into existing tools and databases - Working prototype delivered at week 4 ## AI Workflow Automation Eliminate manual data entry and cross-system copying We build custom automation pipelines using n8n, Zapier, Python, and AI — connecting your tools, automating repetitive tasks, and eliminating the hours your team spends copying data between systems. Average 15–20 hours saved per employee per week. - n8n and Zapier workflow design and build - Python automation scripts and scheduled jobs - API integrations between any combination of tools - AI-augmented workflows (classification, extraction, summarization) - Monitoring and alerting on automation health ## Legacy System Modernization Zero-downtime migration from outdated to maintainable We replace outdated software with modern, maintainable code — without stopping your operations. Our parallel-run migration approach means both systems run simultaneously until the new one is validated, then we cut over. No surprises, no downtime. - Parallel-run migration (old and new system run simultaneously) - Full data migration with integrity verification - Modern stack: Next.js, Python, PostgreSQL, TypeScript - Documentation and internal handoff training - Post-launch support for 90 days minimum ## Custom Software Development Full-stack apps, APIs, and integrations — built to spec From MVP to enterprise-grade production systems, we build full-stack web applications, REST and GraphQL APIs, and third-party integrations. Fixed-price with a written scope before we start — no moving targets, no hourly billing surprises. - Next.js, React, TypeScript front-end applications - Node.js, Python, and PostgreSQL back-end systems - REST and GraphQL API design and development - Third-party integrations (Stripe, Salesforce, HubSpot, etc.) - Scalable architecture designed for your growth trajectory ## AI software development: from automation to AI-native products AI software development at Code and Trust covers the full spectrum: LLM pipelines that automate specific manual workflows, RAG systems that let AI reason over your proprietary data, and ground-up AI-native product builds for founders. Every engagement begins with a structured audit to identify where AI creates genuine operational leverage — not where it sounds impressive. The difference between effective AI software development and AI theater is specificity: we target the exact workflows costing you the most in manual labor, build AI pipelines that handle them end-to-end, and measure the outcome in hours reclaimed and cost reduced — not "AI readiness scores." ## Services FAQ Common questions about Code and Trust services center on pricing, timeline, and what 'fixed-price' actually means. Every engagement starts with a written scope document so there are no billing surprises — and no change orders for scope creep caused by our own estimation errors. ### How much does an AI implementation or custom software project cost? Projects are fixed-price, typically $25K–$150K depending on scope and complexity. We scope and price from the workflow audit — you get a written proposal with exact deliverables before we start. No hourly billing, no change orders for our estimation errors. ### Do you work with companies that have no existing AI systems? Yes — most of our clients start with zero AI in place. The workflow audit identifies the highest-ROI automation targets first. We don't recommend implementing AI where it doesn't clearly improve your numbers. ### Can you modernize a legacy system without downtime? Yes. We run the new system alongside the old one, validate data in real-time, and cut over only when both systems agree. Zero-downtime migration is our default approach — we haven't had an unplanned outage on a migration in 6 years. ### How long does a typical engagement take? AI implementations and workflow automation projects run 8–12 weeks. Legacy modernization varies by system complexity — 12–24 weeks is common. Custom software from zero to production is typically 8–16 weeks for an MVP. We deliver working prototypes at week 4 on all build engagements. ### What's included in post-launch support? All projects include 90 days of post-launch support: bug fixes, performance tuning, workflow adjustments as your team adapts, and minor feature additions that fall within the original scope. Extended retainers are available for ongoing iteration.
