Telliscope allows users to discover new companies, follow industry trends, read important reports, and use AI search to find what they need quickly. At its core, the platform aims to bridge the information gap that exists in many emerging markets, with a focus on making African economies more accessible to global stakeholders.

To bring this ambitious vision to life, the Telliscope team partnered with us to build a data-rich, AI-enhanced web platform from the ground up. The product needed to deliver a seamless user experience, advanced backend architecture, third-party integrations and personalization features while remaining highly scalable and intuitive for its user base.

Telliscope was a complex business platform requiring advanced backend architecture with a highly personalized user interface.

    🔹 Personalized dashboards showing tailored company trends, curated news, events, and data based on user preferences.

    🔹 Advanced backend content management capable of handling multiple data types such as RSS news feeds, event listings, statistical datasets (e.g., from IMF), and PDF reports with AI-backed summarization.

    🔹 AI-powered semantic search that understands user intent and returns structured, meaningful results across text, reports, and datasets.

    🔹 User management workflows: email invitations, permission levels, analytics tracking, and logging.

    🔹 Solid architecture that would support vector databases, third-party API integrations, and scalable AI models.

Our team built a modular, scalable web application capable of managing both structured and unstructured data while delivering intuitive intelligence features:

    🔹Designed backend around NestJS + GraphQL to support flexible APIs that serve both personalized dashboards and AI search queries.

    🔹Used PostgreSQL and MongoDB for hybrid structured and document storage, plus ChromaDB for vector embeddings used in AI-based semantic search.

    🔹Integrated Gemini models via Vertex AI for natural language understanding, summarization, and contextual search.

    🔹Built a rich frontend experience with ReactJS (Next.js), enabling personalized content areas such as trending companies, curated news, events, and reports.

    🔹Developed an AI search interface to let users pose natural language queries and receive contextual maps of insights pulled from diverse data sources.The tech stack included Nest.js for the backend, GraphQL as API layer, PostgreSQL and MongoDB for data storage, and ChromaDB for handling vector embeddings used in AI-based search. We also integrated Vertex AI’s Gemini models for advanced summarization and natural language processing tasks.

We set up a collaborative workflow focused on transparency, alignment, and rapid iteration.

    🔹Team Size and Delivery
The project was developed in four months, followed by a one-month testing and bug-fixing phase. The core team consisted of a front-end developer, a back-end developer, and a project manager who coordinated the workflow and maintained close collaboration with the Telliscope team.

    🔹Collaboration Model
Throughout the development, we held regular meetings to align on features, iterate on feedback, and ensure that both technical and business expectations were met. The tight feedback loop allowed us to rapidly prototype, test, and refine features like the dashboard layout, AI summarization accuracy, and the semantic search experience.

    🔹 Special Focus on Performance
We paid special attention to performance optimization, given the platform’s reliance on multiple APIs, file uploads, and AI queries. Our infrastructure was deployed on Contabo with Google Cloud services supporting file storage and AI functionality in production.
