Entrepreneur, developer & travel tech founder
building from Frankfurt.
I'm Younus — entrepreneur and tech founder based in Frankfurt, Germany. I founded Trip Begin (OTA travel platform), Tourist eSIM (global eSIM marketplace), and co-founded Cloudlax IT (cloud hosting). I build the products and write most of the code.
01 — About me
Hi, I'm Younus — entrepreneur, founder & software engineer based in Frankfurt.
I grew up in Rajshahi — the mango city, the Padma river, and far too much time in front of a computer screen for a kid my age. After HSC at Rajshahi Govt Model School & College, I moved to Dhaka for my B.Sc. in Computer Science at Southeast University. That's where the serious building started.
Then I came to Germany for my Masters — studying Management & IT in Zwickau, AI & XR in Würzburg, and Software Engineering in Heilbronn. I stayed. Frankfurt became home.
Now I run Trip Begin (an OTA for flights and travel), Tourist eSIM (a global eSIM marketplace), and co-founded Cloudlax IT (a hosting & cloud platform). By evening: espresso, a book, or a boarding pass.

03 — Expertise
Four worlds I move between every single day.
My work sits at the intersection of enterprise software, travel technology and AI — and I'm equally at home in the codebase, the system design doc or the founder conversation.
Software Engineering
Full-stack web, APIs, SaaS platforms. TypeScript, Node, Python, React, Postgres.
Enterprise Systems
ERP-class apps: finance, CRM, helpdesk, HR, payroll, inventory — multi-tenant and audit-ready.
Travel Tech & OTA
Multi-GDS integrations (Amadeus, Sabre, Travelport), bedbanks, full OTA architecture & eSIM.
AI & Automation
LLM apps, RAG, agents and AI copilots — shipped to real users, not demos.
04 — Enterprise Software
The unglamorous work I'm quietly proud of.
Finance, HR, operations, inventory — I've spent years building ERP-class systems for companies across Europe and Asia. Nobody talks about payroll engines at dinner parties, but this is the software that quietly keeps real businesses alive. I find that genuinely satisfying.
Finance & Accounting
GL, AR/AP, multi-currency, tax, audit trails, financial reporting.
CRM & Sales
Pipelines, lead scoring, quotes, contracts and customer 360°.
Helpdesk & ITSM
Ticketing, SLAs, knowledge base, omnichannel support routing.
HR Management
Employee records, onboarding, attendance, performance reviews.
Payroll Systems
Country-aware payroll, payslips, statutory compliance, payouts.
Inventory & Warehouse
Stock, SKUs, barcoding, purchase orders, multi-warehouse ops.
05 — Travel Tech
How obsessing over airports built a career.
Every time I boarded a plane I started wondering how the booking system actually worked — the GDS behind the ticket, the markup logic, the commission waterfall, the mid-office holding it all together. Eventually I stopped wondering and just started building it. Now I know that world inside out.
Multi-GDS Integration
Amadeus, Sabre, Travelport (Galileo / Worldspan) — unified behind one normalized API.
Flight Search & Booking
Low-fare search, PNR creation, ticketing, voids, refunds, ancillaries.
Hotel & Car Aggregation
Hotelbeds, TBO, Expedia TAAP and direct contracts blended into a single inventory layer.
Full OTA Architecture
B2C + B2B portals, agent hierarchies, markups, mid-office, supplier failover.
Payments & FX
Multi-gateway, 3DS, multi-currency wallets, commission engines and ledger.
eSIM & Roaming
Carrier-agnostic eSIM provisioning, top-ups, usage and traveler self-service.

07 — Life Outside Code
I build with code, but I live with curiosity.
Software is half my life. The other half is travel, books, long walks across Frankfurt, cafés in new cities, photography and conversations that stretch past midnight. Every product I build is shaped by the way I live.
Travel
30+ countries and counting. Travel is where most of my product ideas are born.
Coffee & Cities
Frankfurt cafés, Berlin weekends, long walks and slow espressos.
Books & Essays
Founder memoirs, systems thinking, philosophy. Always one tab, one book.
Photography
35mm look, street and travel photography — the world through a frame.
Discipline
Early mornings, gym, deep work blocks. Energy is the real productivity stack.
Music & Focus
Lo-fi, ambient, classic OSTs. Soundtrack for shipping at 2am.

10 — Vision
Code brought me here. Curiosity keeps me going. Travel taught me the rest.
I think the most interesting software comes from people who are curious about the world outside the screen. Travel, people, broken systems, unexpected connections — that's where the real ideas come from.
