# Revnix -- full content for LLMs > Revnix is a founder-led engineering company that builds custom AI agents and modern web platforms on open-source foundations. The core promise is ownership: clients get full source code, no vendor lock-in, and a complete handover. Two service tracks (AI engineering and web engineering) are delivered by the same senior team, from discovery to handover. Founded in 2020 by Mobeen Abdullah (Toptal Top 3%). Works worldwide. Contact: contact@revnix.com. ## What we believe - You own what we build: open-source frameworks, full source, complete documentation, no proprietary lock-in. - Open source is the foundation, not a feature: API-first and modular by default, so systems integrate with what you run today and add tomorrow. - Cloud-native means cloud-native: architected for the cloud from the start, deployable on your cloud or self-hosted. ## Services overview (/services) Two tracks, one team. AI and web engineering on open-source foundations you own. Most engagements combine both, delivered by the same engineers from discovery to handover. Every engagement includes: full code ownership with no lock-in, open-source frameworks throughout, documentation and a complete handover, cloud-native and API-first architecture, scoped engagements (never hourly), and async-first delivery. ### AI Engineering (/services/ai) AI that does real work: agents, automation, chatbots, and RAG, engineered into your operations and shipped to production. What we build: custom AI agents and agentic workflows; chatbots and conversational assistants (customer-facing and internal); workflow and back-office automation; retrieval-augmented generation (RAG) over your data; LLM integrations and AI APIs into your existing stack; document processing, extraction, and classification; internal AI tools, copilots, and dashboards; evaluation, guardrails, and monitoring for reliability. Stack: Python, TypeScript, OpenAI, Anthropic (Claude), open models (Llama, Mistral), pgvector, Qdrant, Pinecone, LangChain, LlamaIndex, deployed on AWS / GCP / self-hosted. FAQ: - Is my data used to train models? No. Your data stays yours. We use providers and configurations that don't train on it, or run open models on your own infrastructure. - Can this run on our own infrastructure? Yes. We can deploy open models and the full pipeline in your cloud or on-prem. - What does ownership mean for AI work? You get the full source, prompts, pipelines, and documentation. No black box you can't operate without us. - How do you keep agents reliable? Evaluation, guardrails, and monitoring are built in, so behavior is tested, not hoped for. ### Web Engineering (/services/web) Platforms built to own: production web apps, SaaS products, and internal tools. Modern, API-first, shipped with documentation and a full handover. What we build: production web apps and SaaS platforms; SaaS MVPs and product builds; internal dashboards, portals, and admin tools; API design and third-party integrations; e-commerce and content-driven platforms; cloud-native, scalable architecture; full code ownership and handover. Stack: Next.js, React, TypeScript, Node.js, NestJS, PostgreSQL with Drizzle ORM, Tailwind CSS, REST / GraphQL / tRPC, deployed on Vercel / AWS / GCP / self-hosted with Docker and CI-CD. FAQ: - Do we get the full source code? Yes, from day one. You own the repository, the infrastructure config, and the documentation. - Can you work with our existing codebase? Yes. We can extend your current stack or build fresh, whichever serves the goal. - What stack do you build on, and why open source? Open-source-first (Next.js, TypeScript, Postgres, and your choice of cloud) so you are never locked into a vendor or a license. - What happens after launch? You hold the keys. Take it in-house, or keep us on a retainer for ongoing work. ## Pricing (/pricing) Transparent starting points; final scope is set after discovery, and the Discovery fee credits toward your build. - Technical Discovery: $299, 1-2 weeks. Strategy and a 3 to 5 point roadmap. Credited toward a Build Sprint. - Production Build Sprint: from $10,000, 4-12 weeks. Core platform delivery with a full handover. (Most popular.) - Operational Retainer: $2,500/month, ongoing. Monitoring, optimization, and support. - Dedicated Team: custom, ongoing. An embedded squad for larger, multi-phase builds. How we work: Discovery (audit operations, map a 3-5 point roadmap), Build (production sprints ship the core platform, API-first and documented), Operate (optional retainer keeps systems monitored, optimized, supported). ## Work / products (/work) Products and open-source tools Revnix builds and ships: - Nextly (https://nextlyhq.com): a TypeScript-first, open-source CMS and app framework for Next.js teams. Code-first and UI-first schemas, no lock-in. - Rext (https://rext.ai): an AI content studio with brand memory, so teams stop pasting brand prompts into every chat. - Ficonz (https://www.ficonz.com): an icon system and toolset for teams who want consistent iconography without designing every glyph. - JSON to TOON (https://jsontotoon.com): a free converter for JSON and TOON formats. No signup, no ads. ## About (/about) An engineering team that thinks like founders. Revnix is led by Mobeen Abdullah, a Toptal Top 3% engineer with more than a decade of full-stack work shipped for teams like KitBash3D, the PCI Security Standards Council, and Owlet. He started Revnix in 2020 after watching too many companies get messy delivery and code they didn't really own, to build the team he always wished existed: one that thinks like founders, cares about craft, and hands clients a stack that is truly theirs. Revnix is a small, senior team: the people who scope a build are the people who ship it. ## Contact (/contact) Tell us about your project. We reply within a day, and the first call is a free technical discovery. Email: contact@revnix.com. Hours: 10:00 AM - 07:00 PM | Mon - Fri. ## Blog (/blog) Notes on AI, web engineering, and building software you own. ### JSON to TOON Format: How It Reduces Token Usage and Speeds Up LLMs (https://revnix.com/blog/json-to-toon-format-how-it-reduces-token-usage-and-speeds-up-llms) JSON to TOON Format: How It Reduces Token Usage and Speeds Up LLMs ### Join Our Team: Exciting New Opportunities Await!
