Inmost

We've delivered 50+ projects across healthcare, fintech, IoT, and SaaS, logging over 6,300 hours on Upwork with a 90% Job Success Score. We don't staff juniors on client work. Every project is led by senior engineers and overseen by our founding team - which is why clients come back. What we build: Full-stack web and mobile platforms (React, Next.js, React Native, Node.js, NestJS, Python), cloud-native AWS infrastructure (EC2, Lambda, RDS, Cognito, API Gateway, CloudFront, SQS, Step Functions, CDK), AI-powered products and chatbots (Amazon Lex, OpenAI, NLP pipelines), IoT and embedded systems (AWS IoT Core, MQTT, firmware integration), and CPaaS/communication platforms (Amazon Chime, IVS, real-time WebSocket systems). AWS is our core strength. Our team holds AWS Certified Developer and AWS Certified Solutions Architect credentials. We've architected multi-tenant SaaS platforms, serverless backends, and healthcare-grade systems with full HIPAA-aligned security practices.
