I build the kind of software that financial institutions and enterprises trust with sensitive data and heavy workloads — SaaS platforms, wealth advisory tools, open banking systems, and hospital management applications across Singapore, the UK, and the USA. My recent work at FATech includes architecting a multi tenant wealth advisory platform for SingCapital — SOC 2 Type II and GDPR compliant, sustaining 10,000+ concurrent requests at 99.9% uptime. At Republic Power, I led engineering for Renci Hospital's patient feedback system, Sengkang General Hospital's bed management solution, and Marina Bay Cruise Centre's internal operations platform. What I bring to your project: ✅ End-to-End Fintech & Enterprise Development Full-stack delivery from database schema to production — React 18, Next.js, Vue 3, Node.js, NestJS, TypeScript, PostgreSQL, Redis, AWS. ✅ Secure, Compliant Architecture Multitenant SaaS with database-per-tenant isolation, JWT, OAuth 2.0, RBAC, Row-Level Security — built for SOC 2, GDPR, and regulated industries. ✅ Measurable Performance Results 40% faster database performance through query optimisation and connection pooling. 38% reduction in page load times. 30% cut in API response times. Systems handling 10,000+ concurrent users. ✅ Technical Leadership Led 4-engineer frontend teams using Agile/Scrum. Mentored junior developers in React, TypeScript, and TDD. Reduced production bug escape rates by 30%. ✅ Mobile & Cross-Platform Enterprise mobile apps (Kotlin, Swift, React Native, Flutter) with CI/CD via Fastlane — delivered for healthcare and government clients. Recent highlights: • Wealth advisory SaaS — NestJS + PostgreSQL, multitenant, SOC 2/GDPR compliant • Open banking migration — Next.js/TypeScript, 40% reduction in technical debt (Banfico, UK) • Hospital & kiosk systems — IoT integration, MQTT/UART, real-time dashboards • IEEE-published ML research (TENSYMP 2020) I work best with clients building regulated, data-sensitive, or high-traffic products who need an engineer who understands both architecture and compliance — not just code. Currently completing my MSc in Software Engineering at Universiti Putra Malaysia. Message me with your project scope — I respond within 24 hours.

I cut API latency by 70% and smoothly process €1.5M/month in Stripe transactions for 60K+ active users. I am a Senior Backend Architect specializing in scaling high-traffic SaaS platforms. When your database bottlenecks, your cloud compute bill balloons, or your payment webhooks fail under load, I build the infrastructure to fix it. I scope the architecture upfront, deliver asynchronous updates twice a week, and ensure zero downtime. Core Expertise: - High-Scale APIs: Node.js, Python (FastAPI), REST & WebSockets. - Serverless & Edge: Cloudflare (Workers, KV, D1) & AWS (Lambda, RDS, API Gateway). - Mission-Critical Data: PostgreSQL, Redis, RabbitMQ, Stripe integrations, and HIPAA-compliant architecture. - AI Pipelines: RAG pipelines, OpenAI integrations, and vector databases.

I build full-stack applications and automation systems that save businesses real time and real money. If your backend is becoming a mess, your team is still doing work that should be automated, or your product feels slow, the system wasn't built to scale. That's exactly what I fix. With 3+ years of hands-on experience, I don't just ship code. I build systems that are clean, reliable, and grow with your business. What I deliver: Full-Stack Development: Fast, modern applications built with Next.js, React, Node.js, and TypeScript. From UI to backend, structured and production-ready from day one. Backend & APIs: Scalable APIs with solid architecture, proper authentication, and optimized database handling using MongoDB and PostgreSQL. No shortcuts, no technical debt. Automation & CRM Workflows: Repetitive work eliminated. Lead handling, data flow, and system integrations automated so your team stops doing things manually and starts focusing on what actually matters. AI Integration: Real AI features built into your product or workflows. Not just basic prompts — practical functionality your team will actually use. Performance & Scalability: Speed improvements and infrastructure that handles growth. Caching, clean queries, and efficient design that holds up when things get busy. 🤝 How we work: Quick Discovery Call: We talk through what you're trying to build or fix. No fluff, just clarity (15–30 min). Clear Plan, No Surprises: I map out exactly what we'll build, how long it'll take, and what to expect. You'll know the full picture before we start. Fast Execution: I build, test, and deliver with regular check-ins. Most projects ship within days, not weeks. Handoff & Support: You get something you can actually maintain and rely on. And I'm available after delivery if you need improvements or scaling support. I'm comfortable jumping into unfamiliar codebases and figuring things out fast. Show me your stack and your problem, I'll have a solution mapped out before most developers finish reading the brief. Free consultation included. Send a message and let's figure out where your biggest bottleneck is.
