Six capabilities
What we build,and what it takes.
Each one lists the problem it solves, what we actually build, the stack, and the project that proves it. The timelines are estimates from scope, and we replace them with a real one after the first conversation.
Product and platform engineering
The problem
You need a system, not a feature: something transactional, multi-user, deployed, and still correct in a year when someone else is maintaining it.
What we build
A backend where the consistency boundary is a database transaction rather than a hope, a typed interface on top, migrations that reverse, and the deployment and release pipeline underneath. In your repository from the first commit.
- Estimated timeline
- 8 to 20 weeks, scoped to something running early
- Stack
- FastAPIPostgreSQLNext.jsTypeScriptDocker
- Evidence
- A full back office — till, stock, purchasing, invoicing and accounts — running as one product, in Nexora AI.
AI systems that stay inside their limits
The problem
You want an assistant over your own data, and you cannot have it inventing figures or reading records the user is not allowed to see.
What we build
Retrieval scoped to the caller's permissions, a whitelist of tools the model selects from rather than composes, and a grounding check that every number it states appeared in a real result. The model never writes a query.
- Estimated timeline
- 6 to 14 weeks, alongside the system it sits on
- Stack
- QdrantTool whitelistingGrounding checksPython
- Evidence
- An assistant that answers from a business's own records and cannot state a figure that is not in them, in Nexora AI.
Data integrity and correctness
The problem
The numbers stop agreeing. Somewhere between two systems, or two concurrent requests, a value goes missing and nobody finds out until an audit.
What we build
Money as decimals end to end and as strings across the API. Ledgers as the source of truth with balances as a cache. Row locking where concurrency actually bites. Immutable posted entries enforced by database triggers.
- Estimated timeline
- Part of the build, not a separate engagement
- Stack
- PostgreSQLSQLAlchemyAlembicDecimal arithmetic
- Evidence
- A checkout that writes the sale, the stock, the cash, the tax and the ledger together or not at all, in Nexora AI.
Security and tenancy
The problem
Your data sits next to someone else's, and isolation is a property of your code rather than of your infrastructure.
What we build
Isolation in independent layers, defended by a test suite whose job is to breach it. Tamper-evident audit chains, field-level encryption, and refusals that do not confirm what they are refusing.
- Estimated timeline
- 4 to 10 weeks, or continuous alongside a build
- Stack
- Row-level securityMFAField encryptionAudit chaining
- Evidence
- Each business's data separated by three independent mechanisms, tested by a suite built to break them, in Nexora AI.
Machine learning and computer vision
The problem
You need forecasting, detection or classification on your own data, and an off-the-shelf model does not know your categories.
What we build
Pipelines built against a named benchmark with per-class results, so the classes that fail are named rather than averaged into a headline. Deployment and monitoring included.
- Estimated timeline
- 8 to 16 weeks, depending on annotation
- Stack
- PythonForecastingAnomaly detectionPyTorch
- Evidence
- Stock-out warnings and demand trends surfaced before they become a problem, in Nexora AI.
Bilingual and Bangla-first systems
The problem
Your documents, tickets or transcripts are in Bangla, or in Bangla and English mixed together, and the tooling you have tried was validated on English.
What we build
Tokenisation and normalisation that treats each language on its own terms, code-switched input handled directly rather than routed by language detection, and OCR tuned for Bangla conjuncts and vowel signs.
- Estimated timeline
- 6 to 12 weeks, depending on how much of the corpus is scanned
- Stack
- Bangla OCRCustom tokenisationMultilingual embeddings
- Evidence
- A bilingual interface end to end — English and Bangla on the same screen, not behind a locale switch, in Nexora AI.
