01Manifesto
I build software that runs real businesses — booking engines, hospital systems, restaurant platforms — and AI that people can actually trust.
Engineered in Dhaka. Built for anywhere.
02Selected work
Four platforms.
Shipped in 2026.
Travel, restaurants, healthcare and retail. On each one I owned the whole path — from the first conversation to launch and support.
01/04Travel · Booking platform
IRoomsBD
A complete travel-booking platform for Bangladesh — flights, hotels, tours and transport, in Bangla and English.
- Flights (one-way, round-trip, multi-city), hotels, tours, transport and deals in one checkout
- Admin control center for the booking lifecycle, payments, cancel-and-refund, users and roles — plus a B2B agent program
- Bangla and English, a live currency converter, an AI travel-assistant chat and an interactive map of all 8 divisions
02/04Restaurants · SaaS product
DineDeck Enterprise
An operating system for restaurants — 12 modules on one backend, from the online storefront to the kitchen display.
- Storefront, QR dine-in, POS, kitchen display, inventory, CRM, analytics, delivery and multi-branch — one permission engine across 9 roles
- White-label: every restaurant gets its own domain, private database and branding
- bKash, Nagad and Rocket (plus Stripe and PayPal), split bills and 80 mm thermal receipts with VAT
03/04Healthcare · Hospital management
CareDesk HMS
A multi-tenant hospital management system, built with Famous Specialized Hospital in Dhaka — secure by design, with zero runtime dependencies.
- A staff console for 9 roles — from reception and cashier to clinician, lab reviewer, pharmacist and auditor
- Lab workflow where a different reviewer must release every result; BDT billing on an immutable ledger
- TOTP MFA, CSRF protection, idempotency keys and an HMAC-chained audit log; optional AI summaries stay drafts until a clinician reviews them
Illustration · private system, walkthrough on request
04/04Retail · E-commerce
Maryam Technology
An online store for a POS hardware and consumables retailer in Bangladesh, designed around the client’s own photography.
- Storefront with catalog, search, accounts, quotation requests, orders and tracking — plus a separate admin dashboard
- An interactive POS setup guide, inside a premium redesign built around the client’s photography
- Node.js 24 and native SQLite with no external packages; launched with domain, SSL, business email, docs and a year of support

04Process
Four gates.
No surprises.
Every project moves through the same pipeline. Each gate ends with something you can read, click and sign off.
- gate 01Discover
We talk through the problem and the people it affects. You get a written scope, a timeline and fixed-price milestones.
- gate 02Design
Flows and screens before code, so you can see the product early — and change your mind while it’s cheap.
- gate 03Build
Regular written updates and Loom walkthroughs, with a staging link you can click at every milestone.
- gate 04Launch & support
Deployment, domain, SSL and email — then documentation, training and support after go-live.
04Principles
Six invariants.
The rules every project is held to — each one with evidence you can check.
- INV-01Fewer moving parts
Every dependency is a future bug, bill or breach. I start with the platform and add libraries only when they earn their place.
evidence CareDesk HMS and Maryam Technology run on Node.js 24 built-ins — zero runtime dependencies.
- INV-02Security from version one
Multi-factor sign-in, audit trails and least-privilege roles are cheaper to design in than to bolt on later.
evidence CareDesk launched with TOTP MFA, CSRF protection and an HMAC-chained audit log.
- INV-03Built for Bangladesh, ready for the world
Local payments, Bangla and real-world networks — held to the same standard as any global product.
evidence bKash, Nagad and Rocket in DineDeck; Bangla and English across IRoomsBD.
- INV-04AI with a human in the loop
AI should save people time, not take decisions away from them. It cites its sources and waits for review where it matters.
evidence CareDesk’s AI summaries are off by default and stay drafts until a clinician signs off.
- INV-05Measured, not guessed
Claims about speed and quality come with numbers — load tests, backtests and evaluation suites.
evidence p99 41 ms ingest in Pulse · zero jobs lost at 1,000 in Conveyor · F1 83.8% in Tripwire.
- INV-06A handover you can run with
You own the code, the domain and the documentation. No lock-in, no mystery.
evidence Maryam Technology: docs, a maintenance runbook and a year of support.
05Research
I study how AI fails, so yours doesn’t.
My research asks when language models can be trusted — especially in Bengali, where benchmarks are thin and contamination is easy to miss. It shapes how I build AI for clients: evaluated, cited and reviewed by people.
PreprintResearch Square · Aug 2026
Memory or Generalization? Temporal Probing of Data Contamination in Bengali LLM BenchmarksIntroduces temporal probing: legacy benchmark items paired with difficulty-matched post-cutoff twins, to measure how much of a model’s score is memory rather than skill — 84 matched pairs × 7 open-weight models.

06Open lab
28 systems, built from scratch.
The hard parts of enterprise software — authorization, encryption, queues, fraud models — implemented without domain libraries. Each repo documents its design decisions, benchmarks and what it simplifies.

08About
Hi, I’m Tanha.
I’m a full-stack and AI engineer from Dhaka. I founded Innovera IT in 2023 to build the kind of software I wanted to see more of — honest about what it does, secure by default and simple to run.
Most of my work sits where business operations get messy: bookings, kitchens, clinics and stores. I like turning those processes into calm, dependable systems — and owning the whole path, from the first conversation to the handover document.
Outside client work, I keep a public lab of 28 systems and research how large language models behave in Bengali. Innovera IT is a Shariah-compliant company, so I’m happiest on work in education, healthcare, SaaS and ethical finance.
