Our Process

A structured delivery model from discovery through launch and ongoing support.

  1. Architecture & data model

    We map domains, SLAs, and data constraints—then design APIs and PostgreSQL schemas before feature churn locks in bad models.

  2. Build & harden

    Iterative API delivery with tests, load smoke checks, and integration against your frontends and third-party systems.

  3. Operate & scale

    Deploy with monitoring, then tune queries, caches, and capacity as real traffic arrives.

Technologies We Use

NestJS, Node.js, ASP.NET Core, PostgreSQL, GraphQL, Redis, SQL Server, Docker, AWS, Azure

    Marketplace API

    AutoApp Backend

    Challenge: A Pakistan car marketplace needed faceted search, dealer and identity verification, favorites/reports, and infrastructure that can grow with listing volume—from an API-first modular backend. Without a coherent marketplace api foundation, AutoApp Backend stakeholders faced fragmented tools, slow handoffs, and limited visibility—classic failure modes Tekvers designs against.

    Solution: AutoApp Backend: NestJS car marketplace API with Elasticsearch faceted search, Redis caching, Prisma/PostgreSQL, and dealer/CNIC verification workflows. Production-shaped API scaffold for high-volume car listings. Tekvers delivered a maintainable marketplace api system for AutoApp Backend using NestJS, PostgreSQL, Redis, Elasticsearch, with phased rollout, operator workflows, and documentation suited to long-term ownership.

    Velay

    Challenge: Sports venues needed booking, live floor operations, payments, inventory, and customer channels in one system—but existing tools were generic SaaS or offline spreadsheets that could not handle multi-tenant isolation, Pakistan payment reality, or realtime facility views.

    Solution: Velay: Velay—Pakistan sports & gaming venue SaaS with live court ops, map booking, Pakistan payments, and multi-surface realtime. End-to-end booking → live session → checkout loop across App, Pro, Dashboard, and API.

    Multi-package UK transfer booking platform

    Taxi App Platform

    Challenge: A UK transfer operator needed online booking, fleet/pricing configuration, composite fares, and payment initiation across admin and multiple rider UIs—without claiming live notification delivery or a driver app the repo does not contain.
