Can anyone recommend a reliable MongoDB team for a complex project?

[zeyazukini813]

I’m planning to rebuild part of our data architecture and move to MongoDB, but I need a team that truly understands how to handle scalability, indexing, and performance optimization for large datasets. I’ve worked with freelancers before, but it’s always a gamble — some know the basics, few know how to build a system that actually performs under load. Can someone share a personal experience with a solid MongoDB development partner who delivered real results?
