Software development services from Sri Lanka
Revwald is a Sri Lanka–based software company. Our senior engineers in Colombo build AI, machine-learning and custom software for clients in the United States, the United Kingdom, the Gulf and worldwide — with one accountable owner on every engagement.
AI Product Development
LLM apps, agents and copilots taken from prototype to a production system your team can run.
We design and build AI products around a real workflow — a support copilot, an internal agent, an AI feature inside your SaaS. Every build starts with a scoped plan and a 2–4 week proof of concept against your data, so you see it working before committing to the full build.
- Proof of concept against real data, with a go / no-go decision
- Production LLM application with evaluation and guardrails
- Handover documentation and an owner your team can call
Machine Learning & Forecasting
Models for demand, risk, pricing and anomaly detection — trained on your data, monitored in production.
We build classical and modern ML models where they pay for themselves: demand and inventory forecasting, credit and fraud risk, dynamic pricing and anomaly detection. Models ship with monitoring so drift is caught before it costs money.
- Data audit and baseline model
- Production model with retraining and drift monitoring
- Dashboards that explain predictions to the business
Generative AI & RAG
Private knowledge assistants grounded in your documents, with guardrails and evals.
Retrieval-augmented generation (RAG) lets staff and customers ask questions of your own documents — policies, manuals, contracts, tickets — and get answers with sources. We build the ingestion, retrieval, evaluation and access controls, not just the chat window.
- Document ingestion and secure retrieval pipeline
- Answer quality evaluations and guardrails
- Role-based access so people only see what they are allowed to
AI Integration & Automation
AI wired into the ERPs, CRMs and support desks you already run — with humans kept in the loop.
Most value comes from AI inside existing tools rather than a new app. We connect models to your ERP, CRM and helpdesk to draft, classify, summarise and route work, with human review where the stakes are high.
- Integration with your existing systems and APIs
- Human-in-the-loop review flows
- Audit trail of what the AI did and why
Data Engineering & MLOps
Pipelines, feature stores and deployment plumbing that keep models reliable after launch.
AI is only as good as the data and infrastructure under it. We build the pipelines, warehouses, feature stores and deployment tooling that keep models accurate, observable and cheap to run.
- Data pipelines and warehouse modelling
- CI/CD for models with automated tests
- Cost and performance monitoring
Custom Software & SaaS
The secure, multi-tenant application layer around your AI — built for scale.
Beyond AI, we build complete web platforms and SaaS products: multi-tenant architecture, authentication and roles, billing, admin panels and APIs. Weekly demos of running software keep you in control of scope and budget.
- Web application or SaaS platform, production-ready
- Automated tests, security scans and deployment pipeline
- Support and maintenance on a retainer
Fractional CTO & AI Advisory
Senior technical ownership — roadmap, architecture, vendor calls and hiring — for a defined slice of the week.
For companies that need senior technical leadership before they need a full-time CTO. A fractional CTO owns the roadmap, architecture and vendor decisions, keeps freelancers and agencies accountable, and helps you hire.
- Technical roadmap and architecture review
- Vendor and build-versus-buy decisions
- Hiring support and team setup
Product Accelerators
ZekiSales, Cogni Arkiv, Heilarc and RostLoop — licensed and tailored to cut months off delivery.
Instead of starting from a blank repository, many projects start from one of our proven platforms and are tailored to your business. That means a working release in weeks, not quarters.
- Licensed platform tailored to your workflows
- Data migration from your current system
- Training and rollout support
UX Research & Design
User research, flows and interfaces that make AI-driven products clear and easy to use.
Good AI products explain themselves. We run user research, map flows and design interfaces that make AI output understandable and trustworthy — then hand engineers designs they can build directly.
- User interviews and usability testing
- Flows, wireframes and high-fidelity UI design
- Design system ready for engineering
Digital Marketing
Campaigns, SEO, AEO and content that grow awareness and convert visitors into customers.
We help software and service companies get found: technical SEO, answer-engine optimisation (AEO) so AI assistants can cite you, content strategy and campaigns measured against real conversions.
- Technical SEO and AEO audit with fixes
- Content strategy and production
- Campaign setup and conversion tracking
