About

Hi, I'm Fadel Muhammad Nasution.

I turn business problems into tech solutions that actually work.

With over 5 years as an IT Business Analyst, I sit at the intersection of business and technology, turning messy requirements into clear roadmaps and keeping every stakeholder aligned from discovery to delivery. I've helped teams move faster, build smarter, and ship products that hold up long after launch.

What sets my approach apart: I don't just document what needs to be built. When it speeds up validation, I prototype it myself. Technology should serve strategy, not define it.

Currently open to Senior BA / Product Analyst roles and select consulting projects. If that's what brought you here, let's talk.

My Why

  • Technology & Innovation

    I get genuinely excited when the right tool changes how a team operates. AI, automation, multi-channel platforms. I'm always exploring what's worth adopting and what's just noise.

  • Strategy & Solutions

    I like hard problems. Taking a tangled business challenge and working it into a clean, executable strategy is the part of the job I look forward to most.

  • Product Development

    From the first user interview to the final spec, I care about the full journey. Good products aren't accidents. They're the result of asking the right questions early.

  • Continuous Growth

    The field moves fast and I move with it. I actively follow trends in agile, digital transformation, and product thinking so I can bring real perspective, not just process.

  • Performance & Balance

    Sports, music and cinema keep me sharp outside of work. I've found that the best ideas don't come from grinding harder. They come from showing up rested and curious.

WhatsApp Business Authenticator

Secure OTP Verification via WhatsApp Business API.

Overview

This is a self-initiated demo project built to showcase a production-ready approach to mobile number verification through conversational messaging. It shows how I translate a security requirement into a working, testable flow, not just a spec document.

Objective

To design and demonstrate a mobile number verification flow that is secure, compliant, and scalable, combining chat-based interaction with robust, backend-driven validation for real-world use cases.

Key Highlights

• Multi-Channel Support: Seamless integration with SMS, WhatsApp (WABA) and Telegram for maximum user reach.
• Secure Verification Logic: Implemented robust algorithms for OTP generation, validation checks and automatic session expiry.
• Comprehensive Test Coverage: Documented detailed requirements for all success scenarios and failure recovery mechanisms.
• Flexible Access Methods: Supports instant initiation via QR-Code scanning or direct deep links.
• Proof of Concept: Features a live simulation that mimics real-world processing times and user interactions.

Real-World Application & Use Cases

In a production environment, this system uses secure messaging APIs (e.g., WhatsApp Business API) to automate the exchange. Users send a unique token to a business account; the backend matches it to the user's session and verifies their identity without requiring app installations or complex login flows.

• Two-factor authentication (2FA)
• New user onboarding and identity confirmation
• Account recovery workflows

Technology Stack

Component Production Proof of Concept
Frontend React.js, Tailwind CSS Apps Script
Backend Node.js, Express.js Apps Script
Database PostgreSQL, Redis -
Chatbot Platform LivePerson or Botpress Botpress
Messaging Channel WhatsApp Business API WhatsApp Business API

Business Impact

This approach streamlines identity verification for enterprises: it removes friction in user flows, meets users on channels they already use, and reduces reliance on costly or complex app-based authentication.

Catering Virtual Admin

Eliminating Operational Bottlenecks in Food Service through Automation (WhatsApp Business API).


Catering business owner managing orders manually before automation

Overview

A home-based food business offering catering services for personal events and office gatherings faced operational challenges due to limited customer service capacity. With all customer interactions managed solely by the owner, the business experienced high response times and frequently missed potential opportunities.

The Challenge

Despite steady business growth, manual customer communication processes became a critical bottleneck. A root cause analysis identified the following scalability issues affecting daily operations:

Issue Description
Delayed Responses The owner was solely responsible for both operations and customer communication, resulting in delayed responses. It could take up to 3 hours to reply to inquiries, causing potential customers to disengage.
Lost Opportunities Without real-time interaction, high-intent leads were frequently lost.
No Lead Tracking There was no system in place to record or follow up on inquiries, making it difficult to manage leads or analyze customer demand.
Inconsistent Messaging Information shared with customers varied depending on how the owner responded, leading to misunderstandings or repeat questions.

These problems indicated a clear need for a scalable solution that could handle repetitive queries, capture essential lead data, and ensure timely engagement with customers, all while freeing up the owner's time.

Discovery & Requirements Gathering

To diagnose workflow inefficiencies, I facilitated stakeholder interviews with key operational stakeholders (including the Co-Founder) and performed a qualitative analysis of historical WhatsApp chat logs. This data-driven approach allowed me to pinpoint critical pain points, isolate high-value automation opportunities and ensure the solution aligned with daily operational needs.

Methods Used:

• Stakeholder Interviewing: Conducted one-on-one interviews to capture qualitative requirements and pain points.
• Process/Data Analysis: Analyzed raw customer chat logs to identify repetitive inquiry patterns and automation opportunities.
• Pain Point Mapping: Categorized issues by business process to prioritize which problems to solve first.
• Manual Process Observation: Observed the owner's day-to-day workflow directly to validate patterns found in the chat log analysis.

Some key questions asked during the interview phase:

Category Sample Questions
Customer Behavior - “What kind of messages do customers usually send first?”
- “Are there any patterns in the types of questions asked?”
Operational Workflow - “How do you usually respond to inquiries?”
- “Which part of the conversation takes up the most time?”
Business Goals - “What are you hoping to achieve with automation?”
- “Do you still want to personally close deals, or fully automate?”
Tools & Limitations - “Are you using any tools like Google Sheets, Notion, etc.?”
- “Do you have a budget for CS or CRM tools?”

Pain Point Mapping:

Business Process Pain Point Impact
Receiving Customer Messages Owner manually replies to every inquiry Delayed responses; missed leads during peak hours
Answering Menu & Pricing Repetitive questions from customers Owner's time consumed by low-value, repeated tasks
Lead Qualification Hard to identify serious inquiries early Wasted time on unqualified leads
Data Collection for Orders Owner manually gathers event details (date, pax, location) Inefficiencies and risk of incomplete orders
Customer Follow-Up No record-keeping or CRM system Lost opportunities; no re-engagement

Insights Discovered:

• 80% of customer messages follow a repetitive pattern (menu, price, availability).
• The owner preferred not to fully automate, but wanted help filtering serious leads.
• No customer segmentation or tracking existed yet.
• Owner frequently lost leads when busy cooking or handling events.

The Solution

To address the business's communication challenges, I designed and implemented a WhatsApp chatbot with an intuitive, step-by-step conversational flow that guided customers seamlessly from initial inquiry to order placement. The solution balanced automation with a personal touch, ensuring users felt heard without overwhelming the owner.

Key elements included:

1. Warm, friendly greeting that set a positive tone and quickly identified the customer's intent.
2. Efficient lead capture by collecting essential details: name, event date, location, and guest number, structured to minimize friction.
3. Menu and pricing information presented to help customers explore available options easily.
4. Ordering guidance directing customers to place orders conveniently via food service platforms.

This solution not only automated routine inquiries but also streamlined the customer journey, enabling the business to scale communication without additional staffing.
