Available for selected consulting work
I help companies turn technical complexity into reliable business capability, leading architecture, delivery, modernization, DevOps, cybersecurity, and AI integration across connected systems. I operate as a hands-on Technical Lead, Principal Engineer, or senior engineering leader depending on what the organization needs.
I began my career working closely with servers, networks, databases, and internal business systems. That experience shaped the way I approach software development today. A well-built application depends on more than good code—it also needs reliable infrastructure, strong security, a disciplined delivery process, and a capable team behind it.
As a long-time OpenBSD and NetBSD enthusiast, I have always valued the principles behind Unix systems: simplicity, clean design, security by default, and doing things correctly rather than simply making them work.
Throughout my career, I have worked as a software engineer, systems architect, technical lead, and Head of IT and Engineering. Despite moving into leadership roles, I have remained hands-on. I still review architecture, write backend code, improve deployment pipelines, troubleshoot infrastructure, and help teams work through complex technical decisions.
Hands-on 0-to-1 technology leadership for early stage and growing startups (Fractional CTO, Founding Technical Lead, Technical Advisor). Helping founders turn product ideas into scalable production platforms, guiding MVP architecture, rapid prototyping, cloud infrastructure, AI integration, security, and engineering hiring.
Custom platforms, APIs, microservices, dashboards, internal tools, FinTech systems, integration work and legacy modernization.
LLM applications, Generative AI, Voice AI, RAG, agentic workflows, document processing and API-connected business automation.
Cloud environments, Linux, containers, CI/CD, infrastructure as code, monitoring, backup planning and production troubleshooting.
Secure architecture, API protection, identity and access, infrastructure hardening, vulnerability assessment and security-aware delivery.
Highlight project / React Native Cross-Platform Mobile Architecture
A native cross-platform mobile platform built for EV owners, ride-sharing drivers, and commercial fleet operators. Built from the ground up in React Native for iOS and Android, the app delivers a fluid native experience for real-time station discovery, high-speed camera QR code scanning, dynamic charging budgets, live telemetry monitoring, and tokenized payments via local e-wallets, cards, or QR.
I architected and engineered the end-to-end full-stack solution building the cross-platform mobile experience in React Native alongside real-time IoT hardware communication. The system connects directly with physical EV charging infrastructure via OCPP 1.6 & 2.0 protocols, supported by a scalable TypeScript backend, PostgreSQL database, WebSocket live telemetry streams, and Docker deployment.
Founding Partner, Technical Lead & Solutions Architect

It combines Voice AI interviews, Gemini-based analysis, candidate scoring, ATS integration, backend APIs and recruitment automation to help employers reduce manual screening and make candidate evaluation more consistent.
As Founding Partner, Technical Lead, and Solutions Architect, I drove the end-to-end architecture, backend, AI integration, and cloud infrastructure for Akaza — from system design and DevOps to security and applied AI.
Voice & Conversational AI / Luxury Travel Platform
AI-Powered Voice Concierge transforms how people discover and book luxury travel. By leveraging modern AI and Natural Language Processing (NLP), Eva replaces rigid booking forms and text-based chatbots with a natural, human-like voice experience. Users can simply speak to plan trips, explore destinations, and customize hotel suite reservations in real time.
Beyond listening and speaking, the platform features a responsive visual AI avatar that reacts instantly to voice cues and volume changes, making digital interactions feel as intuitive, personal, and effortless as speaking with a high-end personal concierge.
Enterprise ERP & WMS / Omnichannel E-Commerce
An enterprise-grade omnichannel e-commerce ERP and Warehouse Management System (WMS) built to simplify multi-platform operations for high-volume merchants. It unifies product listings, inventory sync, order routing, and warehouse fulfillment across major marketplaces, including Shopee, Lazada, TikTok Shop, and Shopify.
Engineered for high-volume merchant operations, the platform provides unified multi-channel catalog publishing with dynamic markup rules, synchronized master inventory with safety threshold warnings, multi-warehouse stock reservation, and automated routing for real-time dispatch and label printing.
Full-Stack Product Development / Enterprise HRIS Platform
A comprehensive HRIS portal and workforce intelligence system built for NPK Medical Trading, Inc. The platform features an Employee Self-Service portal, DTR & Biometric Attendance tracking, Benefits Management, and real-time workforce analytics (active headcount, department distribution, tenure, growth trends, upcoming anniversaries, and probationary conversions) alongside dedicated executive reporting hubs for 201 Master Files, Payroll & Compensation, and Staff Training.
I led and executed the complete product development lifecycle from ground up—designing the full-stack architecture, database schema, analytics calculation engine, DTR & biometric integrations, self-service workflows, executive reporting engines, role-based security access, and CSP compliance.

MIS Head
Managed server, network, database and security infrastructure supporting film and post-production operations across a mixed operating-system environment.
A lightweight, real-time host threat detection and prevention engine written in Go. Tails web server access logs in real-time, inspects incoming traffic against high-precision regex threat patterns, tracks suspicious IP hit frequencies, and automatically blocks attacking hosts at both the local Linux firewall level (iptables) and the cloud edge (Cloudflare Firewall API).
I begin with the business problem, the current environment and the real operational constraints.
Architecture, security, ownership and deployment are discussed before they become expensive problems.
Each stage should produce something that can be reviewed, tested and improved.
Logging, monitoring, backup, documentation and support are part of the project—not an afterthought.
