You bring the idea.I architect the system.
I help founders untangle messy AI prototypes, fix broken logic, and build scalable, production-ready backend infrastructure.

AI got you 90% of the way there.
I handle the last 10%.
Building with AI is fast, but it doesn't architect scalable systems. If you're dealing with mysterious bugs, slow database queries, or have no idea how to deploy your local project to the cloud—you don't need a tutorial. You need an architect.
Code that works ≠ Production-ready
Your local prototype runs fine, but scaling it means addressing security, performance, and maintainability from the ground up.
Fast prototypes, slow reality
AI generates code quickly, but debugging logic errors, race conditions, and database bottlenecks requires deep architectural knowledge.
90% done, stuck on critical 10%
Deployment, CI/CD, database migrations, monitoring—the final push to production is where most founders hit a wall.
Productized Engagements
Clear scope. Fixed outcomes. No hourly uncertainty.
The Architecture Guide Plan
per session
For planning before you build, or restructuring a messy codebase.
- Tech stack and infrastructure consulting
- System architecture design (ER diagrams, API design)
- Code planning session to align AI generation with real-world engineering
The Code Rescue Sprint
per sprint
For when the app is broken and development has stalled.
- Targeted bug-fix bundles for AI-generated logic errors
- Refactoring messy, unmaintainable code into clean structures
- Database query optimization (MongoDB, PostgreSQL)
The Deployment Engine
per project
For getting the project off a local machine and onto the web.
- Full CI/CD pipeline setup
- Docker containerization and AWS infrastructure configuration
- Domain setup, SSL, and live launch
Fractional Lead Architect
monthly
For ambitious builds requiring end-to-end development and team management.
- High-level system design and weekly architecture reviews
- Management of specialized, distributed developers
- Complete technical ownership of your SaaS platform
Featured Case Studies
Real-world projects where I helped founders ship production systems, from idea to deployment.
Challenge
Scattered microservices with vibecoded implementations that needed to go live for an investor demo. The system lacked proper containerization, had numerous bugs, and required a reliable deployment pipeline for continuous development.
Solution
Dockerized all services, systematically fixed critical bugs, deployed the application to a VPS with proper configuration, and established a CI/CD pipeline to support ongoing development and rapid iterations.
Outcome
Successfully delivered production-ready system in time for investor demo with automated deployment pipeline.
Challenge
Building a heavy AI media processing platform from scratch that required scalable architecture to handle compute-intensive workloads and complex AI pipeline orchestration.
Solution
Architected the entire backend infrastructure with auto-scaling workers for AI processing, set up isolated cloud environments for development and production, implemented full CI/CD pipelines, and integrated multiple AI microservices for video generation and processing.
Outcome
Production SaaS platform serving customers with reliable AI video generation capabilities.
Challenge
AI-powered EdTech prototype running only locally with bugs and architectural limitations. Needed to transform it into a production-ready MVP for beta testing.
Solution
Fixed critical bugs, improved system architecture and code quality, deployed MVP v1 to production, coordinated beta release for initial testers, identified and hired a suitable development team, and executed a smooth handover with comprehensive documentation.
Outcome
Live MVP with beta testers and sustainable development team in place.
How We Work:
Architect with Vision
When you hire me, you work directly with me—Lakshitha Eranga, your system architect and sole point of contact.
My computer science background brings system engineering skills from OOAD, distributed computing, and parallel processing. As a visionary, I understand how to architect the foundation that founders need to build their business on. We either establish and train a team for you, or I bring in my distributed team to execute the build.
Direct Communication
No account managers or project coordinators. You work directly with the architect who understands your system.
Fast Turnaround
Critical fixes and architecture decisions happen in days, not weeks. No bureaucracy, just action.
Flexible Engagements
One-off rescue sprints, ongoing architecture support, or full-scale builds. Scale up or down as needed.
Transparent Pricing
Fixed-scope packages with clear deliverables. No surprise invoices or scope creep.
Architect with Vision
System engineering expertise meets founder-focused vision. I architect the foundation your business needs to scale.
Founders Who've Been There
Real feedback from SaaS founders who were stuck at 90% and needed the last 10%.
"I needed help setting up AWS S3 for my SaaS, and he got it working. Later, when I ran into issues adding features through Cursor, he jumped in and fixed the flow of the app. Really good at getting things back on track."

Meet Eranga
I am a System Architect and Full-Stack Engineer specializing in backend infrastructure, RAG pipelines, and AI integration.
I spend my days turning fragile concepts into robust applications. Whether you need to fix a broken voice agent or scale a compute-heavy video pipeline, I ensure your ideas don't just stay code—they become real products.
My approach is simple: understand the problem deeply, design for scale from day one, and ship production-ready systems that founders can build businesses on.
