How much does custom web development, front-end engineering, or AI agent implementation cost?

Our pricing follows transparent, fixed-price sprint-based milestones without hidden fees. Front-end engineering & high-converting landing pages start at $799 to $2,499. Full-stack custom web applications and SaaS MVP development range between $2,499 and $5,999. Custom autonomous AI agent systems, enterprise RAG pipelines, and complex automation workflows start from $1,499 to $5,999+. We deliver an exact, itemized scope and fixed quotation following our discovery consultation.

What are your typical project delivery timelines from kickoff to deployment?

Timelines depend on architecture and feature scope. High-performance landing pages and front-end design system builds are typically delivered in 1–3 weeks. Production-ready full-stack SaaS web applications require 3–6 weeks. Custom autonomous AI agents and automated workflow pipelines are deployed in 2–4 weeks. We work in agile 1-to-2-week sprints with staging environment demos and continuous feedback loops.

What tech stacks, frameworks, and AI tools do you specialize in?

We specialize in modern, battle-tested engineering ecosystems: React, Next.js, TypeScript, Tailwind CSS, Vite, and Framer Motion for ultra-responsive front-ends; Node.js, Express, Python (FastAPI/Django), and PostgreSQL for resilient backend architectures; AWS, GCP, Vercel, and Cloudflare for scalable cloud infrastructure; and OpenAI (GPT-4o), Anthropic Claude, Google Gemini, LangChain, LlamaIndex, Pinecone, and n8n for enterprise AI agents and RAG implementations.

Who owns the intellectual property (IP) and source code upon project completion?

You retain 100% intellectual property ownership of all custom source code, design assets, database schemas, prompt engineering templates, and documentation. Upon milestone completion and final payment, we execute a complete repository transfer to your GitHub/GitLab account and sign formal IP assignment agreements with zero vendor lock-in or recurring licensing fees.

How do you guarantee enterprise-grade data privacy and security for AI agent integrations?

Security and privacy are built into our architecture. We implement zero-data retention policies with LLM providers so your proprietary data is never used for model training. For enterprise workloads, we deploy self-hosted vector databases, end-to-end encrypted RAG retrieval pipelines, and private VPC infrastructure on AWS or GCP. We also support using your dedicated enterprise API keys, OAuth 2.0 authentication, and role-based access control (RBAC).

Do you provide post-launch warranties, maintenance SLAs, and ongoing technical support?

Yes. Every project includes 30 days of complimentary post-launch hypercare covering critical bug fixes, performance tuning, and stability monitoring. Afterward, we offer flexible monthly maintenance retainers that include guaranteed 24–48 hour response SLA, dependency updates, security patching, cloud infrastructure monitoring, database backups, and continuous feature enhancements.

Can Falcon Technologies integrate with our existing codebase, team, and third-party tools?

Yes. We regularly augment existing engineering teams and integrate with established legacy systems, microservices, and databases. We seamlessly integrate with third-party APIs (Stripe, HubSpot, Salesforce, Twilio, Supabase, Firebase) and connect to collaboration workflows via Slack, GitHub, Linear, Jira, and Figma.

How does your team ensure optimal SEO, 90+ Lighthouse Core Web Vitals, and responsive performance?

Every web application and front-end we engineer is built with semantic HTML5, server-side rendering (SSR) or static site generation (SSG) with Next.js/Vite, automated JSON-LD schema markup, dynamic Open Graph tags, and optimized asset compression. We test extensively to ensure 90+ Google Lighthouse performance scores, instant sub-second load times, WCAG 2.1 AA accessibility, and fluid responsiveness across all desktop, tablet, and mobile viewports.

Achieving 95+ Core Web Vitals and Sub-Second LCP in 2026

Author: Falcon Engineering Team • Published: September 1, 2026

1. Why Core Web Vitals Dictate Google Search Rankings

Google algorithm updates place measurable weight on real-user page speed metrics: Largest Contentful Paint (LCP < 1.2s), Interaction to Next Paint (INP < 200ms), and Cumulative Layout Shift (CLS < 0.1). Sites that fail these thresholds face severe organic ranking penalties regardless of backlink profiles.

High performance is not something you sprinkle on top of a completed codebase—it is an architectural discipline embedded into asset delivery, CSS compilation, and component hydration.

2. The 4 Golden Rules Falcon Technologies Enforces on Every Build

Critical CSS Inlining: We automate CSS extraction during build time so initial viewports paint in under 200ms.
Font Preloading with WOFF2 Subsets: Preconnecting to font CDNs and preloading Latin character sets ensures zero text layout shifts.
Aggressive Level-11 Brotli Compression: Pre-compressing static JavaScript assets before uploading to CDN edges ensures sub-second downloads even on 4G connections.
Explicit Image Dimensions: Every image and SVG includes width and height attributes to lock in viewport aspect ratios before network assets finish downloading.

Is your website losing customers to slow load times?

We re-engineer legacy websites and front-ends into blazing-fast, 90+ Lighthouse experiences in 1–2 weeks.
