What We Build

Six Kinds of
Custom Software

Platform

🏗️

SaaS Platforms

Multi-tenant cloud platforms with subscription billing, team workspaces, role-based access, and usage analytics. We've built SaaS from zero to thousands of paying users.

Internal

⚙️

Internal Tools

CRMs, ERPs, dashboards, admin panels, and workflow automation built for your exact ops. Off-the-shelf tools compromise; we don't. Your team deserves software that works like they do.

API

🔌

API & Integrations

REST and GraphQL APIs, webhook systems, third-party integrations (Stripe, HubSpot, Salesforce, etc.), and data pipeline connectors. We build the backbone your business runs on.

Data

📊

Data Platforms

Real-time analytics dashboards, ETL pipelines, reporting engines, and BI integrations. Turn raw data into decisions with systems built for accuracy, scale, and speed.

🧠

AI-Powered Products

LLM integrations, RAG systems, fine-tuned models, AI copilots, and intelligent automation. We build AI into your product where it adds real value — not as a gimmick.

Infra

☁️

Cloud Infrastructure

Containerised microservices, serverless architectures, infrastructure-as-code, CI/CD pipelines, and 99.99% uptime SLAs. Your platform, running on solid ground.

Architecture

We Design Systems
That Scale with You

Every system we architect starts with your growth trajectory, not your current load. Hover any node to explore how we think about modern software infrastructure.

━━━Service connection

● ●Live data flow

□Persistent storage

Our Process

12 Weeks.
Spec to Production.

Week 1–2

Discovery & Architecture

We map your users, workflows, and edge cases. You get a full technical specification — data model, API contract, infrastructure diagram, and a firm timeline — before a single line of code is written.

🔭

Week 3–4

Design & Prototyping

High-fidelity wireframes and interactive prototypes for every user flow. We validate with real users before building. Nothing goes to engineering until you've clicked through the full experience.

✏️

Week 5–8

Core Engineering

Two-week agile sprints with a working demo at the end of each. Feature flags, structured logging, and automated tests are wired in from sprint one — not bolted on at the end.

⚙️

Week 9–10

Integration & QA

End-to-end test suites, load testing to 10× expected peak, security audit, and third-party integration validation. We break it so your users don't.

🧪

Week 11–12

Launch & Handoff

Zero-downtime production deployment, runbook documentation, infrastructure-as-code handoff, and a 30-day hypercare window where we're on call for anything that comes up.

🚀

Ongoing

Scale & Iteration

Post-launch retainers covering feature velocity, performance tuning, security patches, cost optimisation, and quarterly architecture reviews as your user base grows.

📈

Quality Code

Code You'll Be
Proud to Own

We write typed, tested, and documented code. Every function has a test. Every endpoint has a schema. Every service has a runbook. Your engineers take over a codebase they understand.

100% TypeScript / type-safe Python

90%+ test coverage on core paths

OpenAPI docs auto-generated from types

Structured commit history with changelog

17 db.users.findUnique

18({ where: { userId } }));

Capabilities

What Goes Into
Every System We Ship

Built Fast. Stays Fast.

We profile query performance, eliminate N+1 issues, add strategic caching layers, and load-test to 10× projected peak before any deployment. Your users never hit a slow page.

Sub-100ms API response targets at P99

Redis caching at query and response layers

Database index optimisation per query plan

Automated load testing in every CI run

Use Cases

Real Systems.
Real Results.

Custom software solves the exact problem no SaaS product quite reaches. Here's how we've done it across five demanding domains.

$ run tests

✓ 142 passed

✓ 0 failed

$ deploy

✓ Live!

Logistics

Real-time fleet dispatch platform

A freight network needed real-time driver tracking, dynamic route optimisation, automated proof-of-delivery, and a live operations dashboard. We built a microservices backend on AWS with a React dashboard — processing 40k location pings per minute at peak.

FinTech

Multi-tenant lending SaaS

HealthTech

Clinical data aggregation system

EdTech

AI-powered adaptive assessment engine

Retail

Inventory & demand forecasting platform

Why Blenvo

What Sets Us
Apart

📐

Spec Before Sprint

We write a full technical specification — data model, API contract, infrastructure diagram — before any coding begins. Surprises happen in the spec, not in production.

🔁

Fortnightly Demos

Every two weeks you see a working build. No black-box development. You approve features before they're finalised, which means fewer rewrites and no nasty surprises at launch.

🏛️

Clean Handoff

At the end of every engagement, you receive the full source code, a documented architecture, a runbook, infrastructure-as-code, and a knowledge-transfer session. No lock-in.

🔒

IP is Yours

Everything we build belongs to you. No licensing, no revenue share, no IP encumbrance. We sign an IP assignment on day one so there's no ambiguity later.

Tech Stack

Right Tool.
Right Job. Always.

We're not married to any framework. We pick the stack that fits your use case, your team's expertise, and your long-term maintenance burden.

Frontend

React / Next.js

Vue / Nuxt

Svelte

Remix

Next.js (App Router) for most web platforms; Remix for data-heavy apps.

Backend

Node / Express

Python / FastAPI

Go / Gin

Elixir / Phoenix

Node.js for real-time; FastAPI for ML-heavy; Go for high-throughput APIs.

Database

PostgreSQL

MongoDB

MySQL

DynamoDB

PostgreSQL as default with row-level security; Mongo for unstructured docs.

Infra

AWS

GCP

Azure

Self-hosted

AWS for most; GCP for AI/ML workloads; Azure where existing enterprise contracts exist.
