Start Your Project

Do I need a WhatsApp Business API account before starting?

No. We handle the full Meta Business verification, WhatsApp Business API onboarding, and number registration as part of our service. We guide you from zero to live.

Is sending bulk WhatsApp messages allowed?

Yes through the official WhatsApp Business API with opt-in contacts. We ensure every campaign is fully compliant with Meta's messaging policies to protect your number from bans.

Can the chatbot hand off to a human agent?

Absolutely. We build intelligent escalation logic so the bot hands off to a live agent whenever it detects frustration, a complex query, or a specific trigger keyword.

Will I own the chatbot and all the flows?

Yes. You receive complete ownership of every flow, template, and integration. Everything is fully documented and handed over after project completion.

“Ziyad and the entire Codex Lancers team have been simply amazing to work with while creating our 11:11 The Divine Mindset mobile app. Communication was outstanding throughout the entire project. They kept us fully informed at every stage, responded quickly, and were always patient, professional and genuinely committed to achieving the best possible result. Their feedback, ideas and suggestions were enormously helpful and significantly improved the finished app. The app they have created is stunningly beautiful in every way, with an elegant, polished design and flawless functionality. They understood our vision perfectly and brought it to life even better than we had imagined. I cannot recommend Ziyad and his team highly enough. Their technical expertise, creativity, attention to detail and dedication are exceptional. We will be using them for all our future app projects and look forward to working with them for many years to come.”

“I’ve been building with Codelancer (Ziyad and the team) for the past plus two years, and I highly recommend them to anyone in need of a reliable development team. They are deeply committed to their clients’ vision, communicate clearly, are impressively responsive, and have consistently turned complex ideas into fully functional products. Codelancer genuinely prioritizes client success. They don’t just write code -they share valuable insights, make thoughtful suggestions, and support you at every stage of the journey. Over time, they’ve become an integral part of our team, and it’s a real pleasure to work with them and have them by our side. I am very grateful to work with them and highly recommend them to all”

“Great communication, excellent coding work, very open to making changes as the projects have developed. My project involved several different computer languages, for Windows, Mac, iOs, and Android. It was great that they had sufficient talent in their team to pull it all together! I have been working with them for the last almost 3 years.”

“Partnering with CodeX Lancers has been one of the best decisions for our project. From the initial UI/UX flow design to API implementation and complete end-to-end product guidance, their team consistently demonstrated strong product thinking. They don’t just execute tasks they ask the right questions, provide thoughtful suggestions, and help refine the overall direction of the product. Their involvement went far beyond development. They contributed strategic insights, improved workflows, and ensured that both the user experience and backend integrations were properly aligned. That level of ownership truly makes a difference. Timelines were respected, communication was clear and consistent, and every discussion felt productive and solution-focused. Instead of working with an external agency, it genuinely felt like we had added a committed product team to our side. Their attention to detail, UI clarity, structured approach, and proactive mindset gave us confidence throughout the entire journey. Highly recommended for anyone looking for a dependable team that genuinely cares about both execution and long-term product success.”

“Ziya contributed to the project and was generally responsive when contacted. The engagement required additional coordination and clarification on some tasks, and timelines were somewhat longer than expected. Overall, a cooperative developer with potential, particularly if project scope and deliverables are very clearly defined from the beginning.”

We have been working with Ziya and his team on three major milestones, and overall, it has been a productive collaboration. The team demonstrated strong technical skills, responsiveness, and a commitment to delivering quality work. Design & Implementation – The team effectively translated our requirements into a visually appealing and functional UI, ensuring a smooth user experience. Timely Delivery – Most tasks were completed on time, and any delays were well-communicated in advance. Before we finished our current project we started to send them more projects.”

“Ziya was incredible to work with on my project. Came to the job with clear directions and clear understanding of what I was looking for. Brought ideas to the table that I didn't think about. Excellent communication. Wonderful project knowledge and was very helpful in explaining a process that I know little about. Would definitely use again!”

“Ziya delivered our field data collection app for 70+ users on time and bug-free. His Flutter/Dart expertise is solid, and he proactively solved complex challenges including offline sync and GPS tracking without being asked. What impressed me most: clear daily communication, clean code that's easy to maintain, and thoughtful suggestions that improved our original design. When integration issues arose, he fixed them independently rather than just reporting problems. Would definitely hire again and recommend to others needing reliable Flutter development.”
