Our Projects

Software built for real operations, real users, and real growth.

We work across web platforms, mobile applications, backend systems, integrations, automation, and product modernization — building complete products and improving the ones you already run.

Data · Automotive

Automotive Data Platform

A platform that aggregates vehicle data from multiple sources and makes it searchable for downstream products.

  • Node.js
  • TypeScript
  • PostgreSQL
  • Redis
  • Docker
  • AWS
Read more

Challenge
Vehicle data arrived from many providers in inconsistent formats, with duplicates and gaps, and had to be queried quickly at scale.

Approach
We designed a normalization pipeline and a canonical data model, then built an API layer with caching so lookups stayed fast under load.

Solution
An ingestion and enrichment service feeding a searchable store, exposed through a documented API with monitoring and clear data-quality signals.

Outcome
Consumers could resolve vehicle records against consolidated data through a single, reliable interface instead of stitching sources together themselves.

  • Node.js
  • TypeScript
  • PostgreSQL
  • Docker
  • GitHub Actions
  • Cloudflare
Read more

Challenge
Teams needed dependable, automated backups across hosting providers, with retries and a clear audit trail when something failed.

Approach
We built a job-based synchronization engine with idempotent runs, structured logging, and alerting, deployed as containerized workers.

Solution
A scheduler and worker system that mirrors data sources, verifies integrity, and surfaces status and history through a simple dashboard.

Outcome
Backups ran unattended and predictably, with failures caught and retried rather than discovered later.

Web · B2B operations

B2B Workflow Management Platform

A web platform that coordinates multi-step operational workflows between teams, with roles, approvals, and an activity history.

  • React
  • Next.js
  • TypeScript
  • Node.js
  • PostgreSQL
Read more

Challenge
Work was tracked across spreadsheets and email, so status was unclear, handoffs were missed, and there was no reliable record of decisions.

Approach
We modeled the real workflows with the team, then built a role-based application with clear states, approvals, and notifications.

Solution
A responsive platform where each task has an owner, a state, and a full history, with permissions matched to how the organization actually works.

Outcome
Teams shared one source of truth for operational work, with visible ownership and an auditable trail of what happened and when.

Cross-Platform Vehicle Utility Application

A cross-platform mobile app that gives drivers quick access to vehicle information and everyday utilities.

  • React Native
  • TypeScript
  • Node.js
  • PostgreSQL
Read more

Challenge
The product needed to ship on both iOS and Android from one codebase, work reliably offline, and stay responsive on modest devices.

Approach
We built with a cross-platform framework, kept the interface simple and accessible, and cached data for offline use.

Solution
A single-codebase application with a focused feature set, offline support, and a release pipeline for both app stores.

Outcome
Drivers got a fast, consistent experience across platforms, maintained from one codebase instead of two.

AI Integration · Knowledge management

AI-Assisted Knowledge and Documentation System

An internal system that makes scattered documentation searchable and answerable using language-model-assisted retrieval.

  • Python
  • TypeScript
  • Node.js
  • PostgreSQL
  • React
Read more

Challenge
Important knowledge was spread across documents and tools, so people struggled to find accurate answers quickly and trust them.

Approach
We built a retrieval pipeline over existing content, added a language model for grounded answers, and kept clear links back to sources.

Solution
A search-and-answer interface that returns relevant passages with citations, so people can verify what they read.

Outcome
Staff found grounded answers faster, with sources attached, instead of hunting across systems.

Legacy SaaS Platform Modernization

A phased modernization of an aging SaaS product — improving stability and performance without stopping delivery.

  • TypeScript
  • Node.js
  • React
  • PostgreSQL
  • Docker
  • AWS
Read more

Challenge
The product carried years of accumulated complexity, which made changes slow and risky and made onboarding new developers hard.

Approach
We stabilized the most fragile areas first, introduced tests around critical paths, and modernized incrementally rather than rewriting everything at once.

Solution
A safer, better-tested codebase with updated infrastructure and a clear path for continued improvement, delivered in reviewable stages.

Outcome
The product became easier and safer to change, with modernization delivered in steps instead of a risky big-bang rewrite.

Web · Retail

E-Commerce Platform Replatforming

Migration of an online store onto a modern web stack, improving page speed and the day-to-day work of the catalog team.

  • Next.js
  • React
  • TypeScript
  • Node.js
  • PostgreSQL
Read more

Challenge
The existing store was slow to load and awkward to update, and the catalog team depended on developers for routine content changes.

Approach
We moved the storefront to a modern, well-structured frontend, kept URLs and SEO intact, and gave the team safe ways to manage content.

Solution
A faster, responsive storefront with a maintainable component library, preserved search rankings, and self-service catalog editing.

Outcome
Pages loaded noticeably faster and the catalog team could make everyday changes without waiting on engineering.

Real-Time Operations Dashboard

A live dashboard that consolidates operational data from several systems into one clear, real-time view.

  • TypeScript
  • Node.js
  • Redis
  • PostgreSQL
  • React
Read more

Challenge
Operational data lived in separate tools, so getting a current, trustworthy picture meant manual work and delay.

Approach
We built a streaming data layer that normalized events from each source and surfaced them through a responsive dashboard.

Solution
A consolidated real-time view with filtering and alerting, backed by a pipeline that keeps the underlying data consistent.

Outcome
Teams could see current operations at a glance instead of assembling the picture by hand from multiple tools.

Container Platform and CI/CD Overhaul

Containerization and a rebuilt delivery pipeline that made releases faster, safer, and repeatable.

  • Docker
  • GitHub Actions
  • AWS
  • Node.js
  • CI/CD
Read more

Challenge
Deployments were manual and inconsistent, which made releases stressful and made it hard to reproduce environments.

Approach
We containerized the services, standardized environments, and built an automated pipeline with checks and easy rollbacks.

Solution
A reproducible container setup with CI/CD, automated testing on every change, monitoring, and low-risk rollbacks.

Outcome
Releases became routine and repeatable, and environments could be recreated reliably instead of by hand.

Subscription Billing Service

A billing and subscription service handling plans, renewals, and invoicing behind a clean, documented API.

  • Node.js
  • TypeScript
  • PostgreSQL
  • Redis
Read more

Challenge
Subscription logic — trials, upgrades, proration, failed payments — was scattered and hard to reason about or change safely.

Approach
We modeled the billing rules explicitly, integrated a payment provider, and covered the critical paths with tests.

Solution
A dedicated service that manages plans, renewals, and invoices through a documented API, with careful handling of edge cases.

Outcome
Billing behavior became predictable and testable, and new plan changes could be made without fear of breaking payments.

Field Service Mobile App

A mobile app for field teams to manage jobs, capture details on site, and sync reliably even with poor connectivity.

  • React Native
  • TypeScript
  • Node.js
  • PostgreSQL
Read more

Challenge
Field staff worked in areas with unreliable networks, so the app had to stay usable offline and reconcile data cleanly later.

Approach
We built an offline-first app with local storage and conflict-aware synchronization, keeping the interface simple for on-site use.

Solution
A cross-platform app that lets teams work offline, capture job details and photos, and sync automatically when back online.

Outcome
Field teams kept working regardless of connectivity, and their updates reconciled cleanly once a connection returned.

AI-Assisted Support Triage

An assistant that categorizes and drafts responses for incoming support requests, with a human always in control.

  • Python
  • TypeScript
  • Node.js
  • PostgreSQL
Read more

Challenge
Support volume made it slow to route and respond to requests consistently, especially for common, repetitive questions.

Approach
We added language-model-assisted classification and reply drafting on top of the existing tools, keeping agents in the loop.

Solution
A triage layer that suggests a category and a draft reply for each request, which an agent reviews and sends.

Outcome
Common requests were routed and answered faster, while agents kept full control over what was actually sent.
