Senior Full Stack Software Engineer · Co-Founder, Vennisys
I build the systems behind the systems.
Senior Full Stack Engineer and Co-Founder with 4+ years of progressive experience, from intern to senior, across a US-based company and a self-founded venture. I architect and deliver enterprise-grade platforms across ERP, healthcare, LMS, inventory, and event management — and increasingly build AI directly into the product, not bolted on top.
Languages, frameworks, infrastructure, and the AI integrations I reach for to ship enterprise-grade products.
Four years building and shipping production systems for a US-based company and my own venture.

// domain expertise
AI-native tools, real-time platforms, and commercial products — delivered across borders.
From Sri Lanka to a US-based company — shipping production systems across time zones.
AI-powered task manager
Collaborative project management app with Kanban boards, team workspaces, calendar view, and a built-in AI assistant for smart task automation and suggestions.
Professional order-flow trading terminal
Professional-grade trading terminal with order flow analysis, real-time market data feeds, and advanced charting for retail and institutional traders.
Premium fashion e-commerce platform
Modern fashion e-commerce platform with premium branding, interactive product displays, checkout flow, and delivery management. Advanced backend functionality is under active development.
Social connection app
Social platform where users generate a shareable QR code/link to spark spontaneous connections, with a real-time sender dashboard and WhatsApp / social media connect for matched users.
Production platforms built for real businesses — ERP, healthcare, events, education, and logistics. Most are under NDA, so they're shown by scope and impact rather than a live link.
Configure-to-order portal for custom safety gear
US firefighter & rescue helmet manufacturer
A login-gated ordering portal for a firefighter & rescue helmet manufacturer. Distributors configure one or more fully-spec'd helmet models and hit a single button — the system builds the order, generates the receipt PDFs, and emails them to both the distributor and the company. It replaced a manual, hand-typed PDF that was the entire order pipeline.
HIPAA-compliant patient care & equipment logistics
US healthcare provider
HIPAA-compliant platform covering the full patient lifecycle: multi-view scheduling, medical-equipment delivery and recurring-supply tracking, EDI clearinghouse integrations connecting multiple provider portals, integrated Gmail + Twilio SMS communications, secure document management, and MFA-protected, role-based access for admins, office staff, and field technicians.
Unified operations across four business lines
US-based multi-service firm (4 service lines)
Cloud ERP unifying Immigration, Accounting, Trucking, and Tax operations into one platform — real-time Kanban task boards, integrated calendar with conflict detection, document management, a built-in phone/email hub, and lightning-fast full-text search, all behind a 4-tier role-based access system.
End-to-end event ticketing & check-in platform
International events & conferences company
All-in-one event platform with QR-code ticketing, 3-second contactless check-in, Stripe payments across 135+ currencies, automated email/SMS campaigns, attendee matchmaking, and live analytics — engineered to stay up under 10,000 concurrent users during peak ticket releases.
Ongoing development across a two-tier LMS platform
JX (in-house SaaS product)
A production LMS already live across two pricing tiers — Enterprise and Small Business — that I took ownership of and kept evolving: new features, performance and scaling work, tier-specific behaviour, and the steady bug-fixing that keeps a live product trustworthy.
Real-time multi-warehouse stock control via barcode
Regional wholesale distributor (5 warehouses)
React Native platform that turns ordinary phones into barcode scanners (UPC/EAN/QR, with ML recovery of damaged codes) — real-time multi-warehouse tracking, automated reorder alerts, guided picking, cycle counting, and ERP/e-commerce integrations, all offline-capable with delta sync.
The OG. Steer with the arrow keys, WASD, swipe, or the pad — eat the apples, don't bite yourself.
BSc (Hons) in Information Technology, Specializing in Software Engineering
Weighted GPA: 3.31 — Second Class Upper Division
Have a product in mind, a system to scale, or a role to fill? I'm always open to a good conversation.
