I'm an Odoo and full-stack developer at DUPNO International in Dhaka. At work I build Odoo 12 modules for the company's vehicle-tracking (VTS) operations — the fleet register, SIM recharge, voice campaigns, tracking certificates, equipment handover and the call-centre desk. Outside them I build Bangla-first SaaS: a Hajj agency platform, a personal finance app, a trading ERP and a digital business card.
A few rules I hold to in every project:
- Bangla first, English one tap away.
- Money is counted in paisa, never in floating point — totals match to the last taka.
- Never break the system next door: an add-on must not slow down or block the module it sits on.
- It ships: tested, deployed on a real server, with backups.
Company work, so the source is private. Screens are from the modules themselves; customer data is blurred.
VTS Fleet 2.0 — a 19,000-row Google Sheet behind a real register: every edit goes through approval, keeps an audit trail and is written back to its exact cell. Python · Odoo ORM · Google Apps Script write-back API · cron retries |
Mobile Recharge — bulk top-ups for the SIMs inside GPS trackers: the operator is read from the number prefix, employees spend from wallets with limits, and the ledger is checked against the live balance. SSL Wireless TopUp API · wallets · computed fields with search |
Voice SMS in Bengali — a renewal reminder as a phone call: one rendered audio file per customer, uploaded to the voice server, dialled, then matched against the carrier's call records. Google Cloud TTS · SSML · SFTP (paramiko) · queue API · CDR reconciliation |
GPS Certificate — the BRTA / BTRC vehicle tracking certificate: type the IMEI and the rest fills itself; a Bengali PDF with a QR code that checks the live status. QWeb PDF · Bengali typeface · QR verification endpoint · onchange |
Asset Handover — who holds which tracker, tool or SIM pack: a handover counts only when both sides sign, open tasks block the close, and what isn't returned becomes a liability. hr · mail · state workflows · record rules |
Call Support Desk — an editable mirror of the PBX call records for call-centre agents, with problem tags and vehicle links, written so it can never make the PBX lose a call. Asterisk PBX · inherited create · non-blocking mirror · chatter |

Ship it. Read it six months later. If it still makes sense, it's done.
