We helped our client transform an early-stage idea into a working MVP ready for real users. Our team started by gathering and refining the client’s requirements, then proposed multiple implementation approaches to identify the most effective path forward.
We designed the complete user journey and delivered the full technical implementation, including back-end development, front-end web interfaces, and a mobile application. The solution also included DevOps setup, gamification features to improve engagement, and seamless integration with the client’s existing WordPress system.
The result was a scalable MVP that enabled the client to validate their concept, onboard real users, and move confidently toward the next stage of growth.
We develop AI-powered apps with advanced LLM/NLP capabilities, domain-specific AI logic, and generative automation. Our expertise includes seamless API/LTI integrations, scalable AI pipelines, and deployment-ready solutions across diverse industries.
We build modern web apps with React/Next.js frontends and powerful backends using Django, Flask, and FastAPI. Our expertise ensures scalable, secure, and high-performance solutions with clean UX, global-ready accessibility, and seamless integrations.
Our comprehensive QA ensures your applications are robust and bug-free. We provide meticulous manual and efficient automation testing, rigorous performance & load testing (JMeter), and critical CI/CD integration (Jenkins, GitHub Actions). Quality is embedded from the start, catching issues early.
Expert ERPNext developers offering end-to-end solutions: module customization, API integration, database setup, customization UI, and accounting automation. We streamline operations with tailored workflows, custom applications, and dashboards for finance, sales, and supply chain management.
Full-spectrum Agentic QA for Crawleo, a real-time web search and crawling API powering AI agents, RAG pipelines, and LLM apps. We ran functional, API, stress and concurrency testing across every endpoint (Bing Search, Google Search, Google Maps, Crawler API, Headful Browser), validated rate limits across Developer/Pro/Scale tiers, tested MCP integrations with Claude Desktop, Cursor, Windsurf and GitHub Copilot, and audited the docs end-to-end. Findings included token storage security issues, broken API parameters, MCP/doc mismatches, pricing inconsistencies, and intermittent 503s — every bug shipped with reproduction steps, expected vs. actual behavior, and suggested fixes. The outcome: tighter docs, hardened endpoints, validated rate limits, and a security posture worthy of a privacy-first brand.

By eliminating the cost and waste of printing physical cards, TapIt offers a modern, sustainable, and flexible way for individuals and businesses to share who they are and stay connected.
Senior engineers, product-minded delivery, and QA you can count on. You ship faster without cutting corners.
Every feature gets reviewed and tested before it ships. Stable releases aren't a nice-to-have. They're how we work.
Solid architecture, sensible performance targets, and clean code so your product runs well today and scales when you need it to.
We think like product owners. We push back, suggest better paths, and ship what actually moves the needle.
Clear roadmaps, weekly delivery, no surprises. You always know exactly where your project stands.
You talk directly to the engineers building your product, not layers of account managers. Straight answers, fast turnaround.
LLMs, RAG, agents, and automation where they actually help your users, not because AI is trending.
Describe your idea and get a roadmap, suggested stack, and rough timeline in seconds.
Free, instant and non-binding. Powered by AI.
Too many agencies hand off code and move on. We stick around. Cortelix builds complete web, mobile, and AI products with QA built in from day one.
Our team handles web apps, mobile builds, AI integrations, and ERP setups. What sets us apart is simple: nothing ships without going through QA first.
We don't call a project done at 'good enough.' We test for stability, edge cases, and real-world usage so you can launch without second-guessing the release.
Whether you need a fast MVP or a full enterprise platform, you get clear timelines, honest updates, and engineers who treat your product like their own.
We Code. We Test. You Grow. That's not marketing fluff. It's how we've delivered across web, mobile, AI, and ERP for clients who needed a team they could trust long-term.
Tell us about your idea and we'll get back within one business day with a tailored plan and next steps.
