Sleekvise bridges modern autonomous AI with enterprise cloud engineering. We build high-concurrency SaaS engines and custom multi-agent workflows, backed by 14+ years of backend mastery to ensure every system remains deterministic, cost-efficient, and secure.
> Engineering Ethos: Engineered for Scale. Built on Trust.
Engineering bespoke cloud software, autonomous agents, and high-concurrency systems.
Production-ready multi-agent workflows, 768-dim pgvector semantic retrieval, and low-latency LLM orchestration. We build deterministic code-level state machines, session-isolated memory, and atomic database locks so agents execute mission-critical business transactions without hallucinating.
End-to-end workflow automation, API development and integration, dynamic web scraping for data warehouses and lead generation, and robust ETL pipelines that transform unstructured web data into structured business intelligence.
High-concurrency customized backends, distributed async queues, enterprise SSO/OIDC integration, and containerized microservice deployments.
Direct architectural advisory, production debugging, code audits, and hands-on guidance for adopting agentic workflows, scalable backend architectures etc.
A multi-tenant B2B conversational commerce engine built by Sleekvise to automate social commerce on WhatsApp. Replaces manual customer chat with an intelligent, trilingual sales agent (Sinhala, Tamil, English, and Singlish), featuring in-flight cart controllers, atomic PostgreSQL row-level stock locking, automated islandwide delivery calculations, and PayHere payment integration.
A proprietary conceptual product by our founder. Architected a production-grade bilingual philosophical AI chatbot grounded in Theravada Buddhist teachings. Features streaming responses, conversation memory, voice STT/TTS, and an asynchronous LLM-as-a-Judge evaluation framework via Gemini API with real-time reliability scoring.
Engineered for the US market for Advantage Group Australasia. High-scale microservices platform supporting multi-tier enrollment, automated renewals, and secure QR-code ticketing. Diagnosed container-level failures and resolved a complex Keycloak OIDC 502 SSO issue. Introduced Redis + Celery for high-volume async ticketing workflows.
Another original conceptual web application founded by our founder that aggregates and analyzes real-time entertainment intelligence from IMDb, Google News, and Audible. Built with automated background scraping routines, interactive charting, and dynamic content scheduling.
An active library of automation scripts, bot engines, and data pipeline utilities spanning social media automation, automated game logic, image processing, and PDF-to-voice modules built with Python, PyAutoGUI, and REST APIs.
Led the complete digital modernization of university processes, eliminating paper overhead by 90%. Automates processes includes student management and enrollment, seminars, examinations, results processing, payments, and convocation.
Led software development at COSTI to engineer the National Innovation Dashboard v1.1. Awarded the eSwabhimani Award for Best System in Government & Open Data Category by the Information and Communication Technology Agency (ICTA) of Sri Lanka.
