Let's transform your ideas into impactful, production-ready solutions!

I'm a software engineer focused on desktop and web apps, mostly in the gaming space. Over the past few years I've built several Overwolf apps with active daily users. I spend a lot of time thinking about stability and how code holds up once you're actually iterating on a live product. My typical stack is Overwolf on the client side combined with serverless AWS in the back. I handle the full flow: game events coming in, processed and routed, UI updating in real time, data going out to Lambda endpoints backed by DynamoDB. Next.js and TypeScript when the project also needs a web dashboard or settings page. Games I've shipped companion apps for include Marvel Rivals, Fortnite and CS2 ,things like match summaries, kill tracking, economy breakdowns, overlays that try not to get in anyone's way. I like the part of the job where you have to actually understand game logic to build something useful, not just wire up an API. I've also done on-chain work when a project needed it: ERC-20 contract design, reward automation with Hardhat, connected to gameplay events through Lambda and Overwolf. Not my main thing, but it's there.

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
