Hi, I'm

Tanjim Ahmmed Shuvo

Software Architect & Systems Builder

I build the systems businesses actually run on. Not a website with a contact form - the real thing: inventory, POS, delivery tracking, admin tools, all wired together. Web, native app, AI, automation - whatever the job actually needs.

ABOUT ME // 01

Architecting Modern Software & Business Systems

Founder & Principal Systems Architect @ Crolop • Founder @ DigifixBD. I design and architect scalable Web Applications, AI Integrations, and Custom Business Systems to eliminate manual bottlenecks and scale operations reliably.

CORE CAPABILITIES ACTIVE STACK

How I Build Solutions

  • 01
    Deep Business Discovery

    I don't push pre-made templates. I start by auditing your workflows, bottlenecks, and customer touchpoints to diagnose where time or revenue is leaking.

  • 02
    Tailored Architecture Blueprint

    Every business model is different. I map out a custom system - aligning web apps, databases, and APIs strictly to your real-world operations before building.

  • 03
    Custom Engineering & Automation

    I build the tools your business actually needs: web platforms, smart automations, and custom workflows designed to cut repetitive manual labor.

  • 04
    AI Integration & Continuous Monitoring

    Practical AI integrations and automations deployed directly into your operations, with ongoing system health monitoring as your business scales.

I started DigifixBD in September 2024 as a digital products venture, but working directly with business owners quickly revealed a deeper problem: most businesses don't need another generic website - they need systems that turn one-time buyers into loyal brand advocates while cutting operational chaos.

Since then, I've evolved DigifixBD into an end-to-end tech and automation partner. Every project is different. Some need practical AI integrations to handle customer queries and operations. Some need direct marketing loops to bring back existing buyers without burning thousands on ads. Others just need messy paperwork automated so nobody is stuck manually reconciling inventory, bookings, or drafting invoices at midnight.

One example - a physical restaurant was bleeding potential repeat customers simply because there was no engagement loop. I built a custom web app functioning as a digital menu, ordering engine, and loyalty ecosystem. Customers earned points and tiered perks across visits, driving direct repeat footfall and slashing marketing waste. For an apparel brand, I automated post-purchase WhatsApp/SMS pipelines and membership tiers, slashing their ad spend by roughly 40% while boosting customer lifetime value.

That's basically how I work on everything - figure out what's actually eating up someone's time or money, then build the exact system that fixes it.
