You know which team, department or process should run better. Maybe it lives in a spreadsheet only one person understands. Maybe it is an app that stopped working, or an idea nobody has tested yet. You do not need a company wide audit. You need a clear plan for that one place, and someone who can build it.
Most projects go wrong at the start: nobody agrees on scope, feature list and hourly rate before the work begins. I start there, with a plan you can read, question and decide on. AI supports every step.

Clarté et conseils honnêtes pour éclairer mes choix
Merci pour votre suivi. Votre rapport d'audit et vos réponses m'ont aidé à comprendre pourquoi il ne serait pas raisonnable de poursuivre la construction actuelle dans la plateforme. Je n'ai pas encore décidé de la suite. Je vais d'abord examiner ses deux feuilles de planning récentes et voir quelles tâches posent réellement problème dans Excel. Cela me permettra de savoir si un Excel amélioré ou un logiciel existant serait utile. Je vais également étudier la liste de solutions que vous m'avez envoyée.
Wonderful to work with and full of expertise
Incredible, thanks so much for your help and expertise on this project! I might hold off on publication for the moment, but I'll probably revisit that idea down the road. Thank you for the research. I will definitely be in touch with you if I need any further work in the future, you've been wonderful to work with. God bless you, talk soon.
Expert advice at no extra cost
Nathanael discussed the challenges I was facing with three related apps and gave me expert advice on how to proceed. Initially, I deployed the three apps separately on three domains but discovered a more efficient way using subdomains. He didn't charge me a penny! It's wonderful to have a strong community and experts like Nathanael help us grow both personally and as a team.
Des conseils précis pour affiner mon prototype avant la production
Avant les conseils de Nathanaël, mon prototype était bien avancé, mais j'avais besoin d'une version plus aboutie pour la mise en production. Je souhaitais un avis sur 3 points : la vérification d'âge, l'optimisation du checkout, et une esthétique plus premium pour sortir du rendu standard. Jeter un œil à la structure de mon appli et me donner quelques conseils m'a énormément aidé à finaliser le projet proprement. Merci d'avoir jeté un œil à mon bazar ! Surtout, merci pour ton temps et ton aide.
Un partenaire sur le long terme, pas seulement un développeur
Nathanael a conçu et développé notre application, Poitourainanjou, en 2024, et le lancement s'est déroulé sans accroc. Il a également contribué à la création de la page d'atterrissage partenaire de l'application. Depuis, l'application a grandi de façon continue. Avoir la même personne, qui a compris le projet dès le départ, disponible pour la maintenance et le dépannage au fil du temps, est vraiment précieux. C'est le genre d'engagement qui est difficile à trouver.
Tells you what you need to hear, technically sharp and refreshingly direct
I came to Nathanael with a complex SaaS idea and limited technical knowledge. He quickly helped me define a precise data model, 22 screens, 6 workflows and a full build specification I now work from every day. He was direct, fast and technically excellent, and told me what he thought rather than what I wanted to hear. I would not hesitate to work with him again.
Turned a Complex Vision Into a Working App
I wanted to take a moment to share how much I've appreciated working with you on the Disciples Path app. From the very beginning, you brought a strong understanding of the platform and helped translate my ideas into something real and functional. I would not have been able to complete the two assessments that are a key part of my app, without your work. What stood out most to me was your responsiveness. Even with a 6 hour time zone difference you were responsive within a short period.
Helpful calls that cleared things up
The calls were very helpful and helped me get a good understanding of what is possible with the software.
Expert guidance and real results. Knowledgeable and genuinely helpful
Nathanael provided a much needed application audit to assist with a recent issue. His expertise and knowledge of the platform infrastructure, coupled with his emphasis on thoughtful naming conventions, provided the insight I needed to move past this blockage. He also encouraged and established a baseline for consistent and reliable backups to prevent data loss. This backup system combines the ability to efficiently test app changes before publication. Thank you sir for being a member of the community!
Reliable Support When It Matters
Thank you for the support you offered throughout this process. I truly appreciated your availability, clarity, and the practical approach you brought to our exchanges, it made a real difference. Your advice about organizing backup folders and versioning the app is excellent. As you said, better safe than sorry. I genuinely appreciated your way of working: clear, structured, and pragmatic.
Gold Standard Service. Exceeded Every Expectation
Your suggestions are gold! Kindness always adds value to a service. Thanks to your input, experience and genuine desire to help, I feel more focused, more motivated, and now have a clearer idea of what needs to be done and how to go about doing it. Thank you also for taking the time to summarise your suggestions so clearly in your follow up email. Another example of how you exceed expectations. I'll be putting into practice your helpful tips and will not doubt be back in touch.
Gained Confidence and Boss Approval with Expert Guidance
My app is going great. I presented it to my bosses and they really liked it. I still need to make a few changes before launching it. Thank you so much for your help, it meant a lot. I learned a lot of things thanks to you, and now I feel really confident with what I'm doing.
Exceptional Support. Grateful for Guidance
Thank you so much for the help, patience, and good energy. Even though I don't have a technical background, all the guidance, structure, and material you shared really helped me move forward, understand the process better, and keep building the app step by step. I'm very grateful for the support and guidance throughout the whole process.
Fast, Skilled Help That Delivered Beyond Expectations
Nathanael recently assisted me with an app I was creating for a fitness challenge my business was hosting. We wanted a platform that was easy to use. It needed to let us manage each entrant with minimal effort, keeping all data in one place. I was struggling with filters, technical roll ups, and linking. A mammoth task for me! Nathanael fixed everything in minutes and delivered a solution better than I could have imagined. He is very skilled and efficient, I would highly recommend his services.
Helpful, Professional Support
Nathanael is extremely helpful and professional when assisting me with the app. He provides clear guidance, answers all of my questions with patience, and makes the whole process much easier. I really appreciate his support.
MVP collaboration
It has been an amazing experience collaborating with Nathanael Boy on the development on the Foundance MVP. With his skills and collaborative mindset we developed in a very short terms an internal MVP to realize the feasibility and usability of our vision, allowing us to takle decisions free from frustrations and time waste.
Reliable App, Reliable Expert
Back in 2022, I needed help organizing a client list. Nathanael created an app that syncs with Google Sheets and is clear and simple for me to use. He listened carefully and understood my needs. I can manage my client list on both Google Sheets and my phone, which is exactly what I needed. Four years later, the app still works perfectly, giving me real peace of mind that I can rely on both the app and Nathanael.
French Speaking Expert Who Teaches as He Builds
From the very beginning of my Poitourainanjou.com project, I searched online forums for a French speaking expert. I was fortunate enough to meet Nathanael Boy to assist me. He immediately understood my expectations and was able to implement them, while explaining the process to me so I could understand its technical aspects and reproduce it on my own. Nathanael Boy is a highly professional expert. He's also a great teacher, always available, calm, yet very responsive.
Reliable Partner for Property Management Solution, 4+ Years Strong
Nathanael built our comprehensive property management application in 2021 and continues to enhance it today. His straightforward approach, professional communication, and rapid development deliver exactly what we need. The application manages properties, tenants, costs, revenue dashboards, and price calculators seamlessly. When the platform provider updated their platform, he proactively rebuilt our app to leverage new features like tables and workflows. Affordable, quality development with excellent support.
