Connecting ideas to outcomes
The interesting problems tend to come from unusual places — equine nutrition, conference technology, AI-powered document cataloguing and retrieval, and systems serving thousands of users who depend on them.

Technical expertise for modern software challenges
Add intelligence to your applications
Integrate LLMs and vision models into your products — document parsing, semantic search, OCR, and RAG systems. I help you add AI capabilities without rebuilding from scratch.
Discuss your AI needs →Design systems that scale
Whether you're modernizing legacy systems, planning a major migration, or architecting something new — I provide hands-on guidance for the technical decisions: system design, technology selection, and migration strategy.
Book a consultation →From concept to production
Full-stack web and mobile development — React and Node.js for web, React Native and Flutter for mobile, deployed on AWS and GCP. I build applications that are maintainable, performant, and ready to grow with your business.
Start your project →Understand what you have
A thorough review of your codebase: architecture quality, security posture, technical debt, and performance bottlenecks. You get a detailed report with prioritized recommendations and a clear path forward.
Request an audit →Real projects. Measurable outcomes.
Extract text from any document and search for specific details — ask for a passport number, get the exact number and the name it belongs to.
Read →Bolt on a new client with modern design instead of rewriting current UI — keeps existing system working and faster path to change.
Read →Fixed seat rooms with screen share, speaking indicators, and waitlisting for post-conference networking — all built on Agora RTC and RTM.
Read →Thoughts on architecture, engineering leadership, and building systems that last.
After limited success with generalised automation platforms, four hours of focused building produced an AI code reviewer integrated into GitLab CI/CD with full codebase context that works exactly the way we needed
4 min →When building an AI pipeline for image cataloguing, we learnt the importance of model optimisation but also the approach of staggered development from a general model to specific
3 min →LLMs don't gradually get better. They hit a threshold where fluent, realistic conversation suddenly emerges. Here's why training scale matters.

I'm Vikram Rao — systems architect, backend engineer, and technology consultant based in Bengaluru. I started writing code professionally in 2003 and have not stopped since.
Over the past 20 years I have worked across startups, enterprises, and independent consulting — building products, leading teams, and taking on the engagements where the architecture decisions actually matter. In 2018 I founded Melluli Technologies to formalise that work. I lead every engagement personally and build the team around it when the work requires it.
The AI landscape has changed what is possible in software — and what clients expect. I am currently deepening my understanding of machine learning and applied mathematics, and building a game — because staying close to hard problems is what keeps the work honest.
