Founder & CEO @ NerdDevs Ltd· AI & SaaS Architect · Full-Stack Engineer
I’m a software engineer turned entrepreneur with 19+ years in tech. I lead NerdDevs, where a 20+ strong team builds AI-driven products, scalable SaaS and EdTech platforms for clients across Asia, Europe and North America. I don’t just manage projects — I architect them: cloud infrastructure across AWS, Azure and GCP, LLM pipelines, messaging systems handling millions of texts monthly, and assessment platforms trusted by the world’s biggest certification bodies.
Platforms I’ve architected and shipped — client work and NerdDevs’ own products, from AI
assistants and messaging backends to assessment systems trusted by global certification
bodies. Some clients stay unnamed; that discretion is part of the engagement.
AI chat companion with GPT-4/5 and Vision-powered image analysis. I designed the architecture and AI pipeline end to end — a high-throughput Node.js backend built to survive viral growth.
100K+ sign-ups in the first three weeks — no service degradation
99.9% uptime across thousands of concurrent AI conversations
Cost-efficient OpenAI usage through caching and resource optimization (MongoDB, Redis, AWS auto-scaling)
An anonymous-SMS consumer app: a second phone number that lives in an app, for texting and calling without handing out your real one. I own the system design behind it — a queue-driven pipeline where deliverability IS the product.
5M+ texts delivered monthly on load-balanced, auto-scaling AWS infrastructure
Idempotent retries and dead-letter handling — transient carrier failures never silently drop a text
Abuse controls and number-reputation hygiene keep carrier compliance and unit economics predictable
Secure online assessment SaaS with remote proctoring — the platform behind high-stakes professional exams worldwide. I architected the core systems and led the engineering team.
Trusted by ACCA, British Council and CIPS — millions of exams delivered
Load-balanced architecture engineered for exam-day traffic spikes and uptime reliability
APIs and third-party integrations for global certification workflows
HealthTech platform bringing AI-enhanced diagnostics to medical imaging. I led the cloud architecture: an Azure pipeline processing DICOM/MRI data under strict healthcare-grade security.
DICOM/MRI processing pipeline on Azure with private endpoints — no public data paths
Infrastructure as code with Bicep; Redis-backed processing workflows
Security-first design for sensitive patient imaging data
AI-enhanced diagnostics in production
