I help startups and growing businesses build scalable SaaS products, AI-powered applications, cloud infrastructure, and backend systems that are designed for long-term growth. Over the last 10+ years, I've worked as a CTO, Engineering Manager, and Senior Full-Stack Engineer, helping companies take products from idea to production while keeping performance, scalability, and maintainability at the core. A few projects I've worked on: • PrepLadder (Acquired by Unacademy) Led engineering for a platform serving over **2 million users**, working on AWS microservices, DRM-protected video streaming, personalized learning systems, and large-scale backend architecture. • Enciser Co-founded an IoT and energy management platform where I designed a serverless AWS architecture for real-time device monitoring, mobile applications (iOS & Android), and cloud-based automation. • Enterprise Platforms Built backend systems, cloud infrastructure, and distributed applications for companies including Zucora, TruckBook, Emerald Planet, and Kryptet, using Go, Python, Kubernetes, Docker, Redis, Cassandra, and modern cloud-native architecture. Across my career, I've helped design and deploy 50+ production applications across SaaS, AI, IoT, marketplaces, fintech, and enterprise platforms. My core expertise • Backend Development Python, Node.js, Go, Django, Flask • Frontend React, React Native, Next.js • Databases PostgreSQL, MySQL, MongoDB, DynamoDB, Cassandra, Redis, ScyllaDB • Cloud & DevOps AWS, Docker, Kubernetes, Terraform, Jenkins, GitHub Actions, Ansible • Integrations Stripe, Twilio, OpenAI, Firebase, Shopify, Slack, SendGrid, Google Maps, Zendesk, and other third-party APIs. What I usually help clients with : ✔ Building scalable backend architecture ✔ AI & LLM integrations ✔ SaaS product development ✔ API design and third-party integrations ✔ Real-time applications using WebSockets, MQTT, and event-driven systems ✔ Cloud infrastructure, DevOps, and deployment automation ✔ Engineering leadership and technical architecture What it's like working with me I don't just write code,I help clients make good technical decisions.I'm comfortable joining an existing codebase, understanding how it works, identifying bottlenecks, and delivering features that are easy to maintain as the product grows. I believe in clean architecture, clear communication, proper documentation, and shipping reliable software instead of quick fixes. I've worked with distributed teams across Canada, Australia, Sweden, and India, and I'm equally comfortable working independently or collaborating closely with founders and engineering teams. If you're building a product that needs to scale, I'd be happy to discuss how I can help. ramansaini.in

Cloud Security & DevSecOps Engineer for teams running on AWS, Azure, GCP, BigQuery, ETL, and CI/CD. I help teams secure cloud infrastructure, data pipelines, and deployment workflows without slowing engineering down. That includes IAM, Entra ID, vulnerability assessment, security analysis, CI/CD hardening, DevSecOps, and information security work across the full environment. Most clients come to me when things already feel messy. Access is too open, cloud infrastructure has grown without clear security rules, CI/CD is moving fast without enough guardrails, and nobody is fully sure where the real risk is. That is exactly why they hire me. I do not just point out issues. I work on the actual infrastructure, access model, cloud setup, and delivery flow so your team can reduce risk, stay organized, and keep shipping with more confidence. 𝙎𝙚𝙧𝙫𝙞𝙘𝙚𝙨 𝙄 𝙊𝙛𝙛𝙚𝙧: 𝟭. Cloud Security Reviews: I review cloud infrastructure, identity, networking, permissions, workloads, and data flows to find real security gaps and give clear priorities. 𝟮. DevSecOps & CI/CD Security: I secure CI/CD workflows so teams can build, test, and deploy with better controls, fewer mistakes, and less production risk. 𝟯. IAM & Entra ID Hardening: I improve IAM, Entra ID, roles, permissions, least privilege, and access design so the right people get the right access without unnecessary exposure. 𝟰. Vulnerability Assessment: I run vulnerability assessment work, validate findings, remove noise, and help your team focus on what actually matters. 𝟱. Security Analysis: I break down risks in plain English so leadership, engineering, and operations can understand what is wrong, what matters most, and what to fix first. 𝟲. Cloud Infrastructure Security: I help secure infrastructure in AWS, Azure, and GCP, including compute, networking, storage, identity, and deployment patterns. 𝟳. Data Engineering & ETL Security: I support secure ETL flows, BigQuery environments, and data architecture decisions where access, movement, storage, and control of data matter. 𝟴. Information Security Support: I help teams improve their information security setup with practical controls, documentation, clearer ownership, and cleaner processes. 𝟵. Quality Assurance for Security Changes: After fixes are made, I verify that the changes actually work and that the environment is more secure, stable, and easier to manage.
