Internal data ⓘWe engineer with regulatory awareness baked in — not bolted on — so your platform is ready for the markets you serve.
Our engineering practices are designed with GDPR principles in mind, including data minimisation, consent management, and right-to-erasure workflows.
We build healthcare platforms with HIPAA-ready architecture patterns — encrypted data at rest and in transit, audit logging, and access controls aligned with PHI handling requirements.
Our development and delivery processes are SOC2-aligned, following the Trust Services Criteria for security, availability, and confidentiality across all client engagements.
We deliver government-grade engineering rigour — documented architecture decisions, formal change management, and compliance-aware infrastructure for public sector and regulated enterprise clients.
Three flexible engagement models designed to match your product stage, team structure, and investment horizon.
Right for you when you have a well-defined product vision, a clear set of deliverables, and want a predictable investment with defined milestones and outcomes.
Right for you when your requirements are evolving, you need flexibility to pivot, or you want to scale engineering capacity up or down as your product grows.
Right for you when you need a long-term engineering partnership — a dedicated squad that operates as an extension of your team, embedded in your processes and culture.

Ajeet Kumar
Founder & Chief Engineering Officer
Ajeet Kumar founded RapidStackLab in November 2025 to give funded founders access to architecture-first engineering without the overhead of an in-house CTO team. He leads a core team of senior engineers with delivery capability across India, UAE, and Europe.
RapidStackLab is an AI-native product engineering and enterprise technology consultancy. We partner with funded startups, high-growth scaleups, and forward-thinking enterprises across the United States, United Kingdom, UAE, and India to design, engineer, and operate mission-critical digital systems. From rapid 6–10 week production MVPs to autonomous multi-agent workflows and global capability centers (GCCs), we deliver architecture-first engineering with 100% intellectual property ownership.
We architect deterministic, production-grade AI agent systems powered by our proprietary RapidCore AI (AgentOS) framework. Leveraging LangGraph, Temporal, LiteLLM, and pgvector, our systems orchestrate multi-agent collaboration with stateful execution, human-in-the-loop approvals, and rigorous regression evals. Unlike brittle single-prompt wrappers, our enterprise agents reliably automate complex multi-step workflows with strict cost controls and 0% hallucination SLAs.
From greenfield SaaS platforms to high-throughput B2B portals, our senior engineering pods build full-stack web and mobile systems designed for extreme scalability. Utilizing Next.js 16, React 19, TypeScript, Python, Node.js, and PostgreSQL, we build resilient architectures featuring event-driven microservices, edge caching, and automated CI/CD pipelines. Every system is built to scale from day one without technical debt.
Downtime costs revenue and trust. RapidStackLab provides 24/7 Managed Site Reliability Engineering (SRE) retainers and cloud architecture services across AWS, GCP, and Microsoft Azure. We implement automated Terraform infrastructure as code, Kubernetes cluster orchestration, OpenTelemetry distributed tracing, and multi-region failover to guarantee 99.99% platform availability while cutting infrastructure spend by 30–50%.
Scale your engineering organization without the risk and overhead of traditional outsourcing. Through our Build-Operate-Transfer (BOT) model, we establish dedicated AI-GCC engineering pods in India tailored to your exact tech stack and culture. Benefit from a 40–50% cost efficiency compared to US agencies, 4 hours of daily timezone overlap, direct Slack collaboration with senior engineers, and a clear legal roadmap for full entity transfer.
Our core team has shipped over 50 production systems across fintech, healthtech, insurtech, GovTech, logistics, and enterprise B2B SaaS. Notable builds include GlobalResearchMarket (enterprise research portal with 63% faster publishing), Insurely (VAPT-certified InsurTech platform with 96% faster issuance), and TASHRA (high-compliance government platform launched in 3 weeks). We work in 2-week agile sprints with transparent weekly demos.
Whether you need to build a new AI-native platform, automate business operations with autonomous agents, or establish a dedicated India engineering pod, start with a 30-minute strategic architecture session. Explore our AI agent development services, review our turnkey GCC & BOT models, or book a strategic architecture call to discuss technical requirements, timelines, and deliverables.
