We deliver complete backend, web, mobile, IoT/wearable device and AI solutions, We are a software engineering agency led by Saidul Islam Bhuiyan, a backend architect with 13+ years of shipping production platforms for companies in the USA, Europe and Asia, including Time Doctor, Wego, Zenius, Exporo, Suprema (BioStar 2) and Telekom Malaysia.

Highlights
- Core parts of Time Doctor's event-driven billing service, moving a 280k+ user SaaS from Stripe to Paddle. Live in about 9 months, it contributed to about $18M a year in savings.
- Real-time hotel metasearch for Wego that pulls rates from 40+ suppliers.
- A microservices LMS and database scaling for Zenius, an EdTech platform with 8M+ registered users.
- A fiat and crypto payment service for Exporo where every transaction moves through an auditable state machine.
- Multi-tenant ticketing for BRTC, Bangladesh's national bus operator, with Android POS terminals across the fleet.
- A UK home care platform where AI drafts rotas for coordinators to approve, and carer onboarding takes about three minutes instead of hours.
- Bluetooth smartwatch sync and Gemini health insights for seafarers, built to work offline at sea.
How we work
We start with the architecture and data model, agree milestones you can see, and own delivery end to end, from code and cloud to monitoring and handover. Code is clean, tested and documented, following SOLID and DRY, so your team can take over. When we add AI, a human approval or a safety check sits between the model and your users.
