Software That Moves Your Business Forward
We build highly responsive, full-stack solutions at incredibly competitive rates — from custom APIs and real-time dashboards to automation and mobile applications.
End-to-End Solutions
From APIs to AI — we deliver production-grade software that handles real workloads, not just demos.
Custom API Development
RESTful and GraphQL APIs built for performance, security, and scale. From market data feeds to payment processing — we handle the hard integrations.
Web Dashboards & Full-Stack Apps
Real-time dashboards, admin panels, and end-to-end web applications from database to deployment. Responsive, accessible, modern stacks, and clean architecture you won't need to rewrite in two years.
TUI / CLI Tooling
Powerful terminal interfaces and command-line tools for power users. tmux-style layouts, real-time data, keyboard-driven workflows.
Automation & Integrations
Connect your systems. We build automation pipelines, ETL workflows, and integrations that eliminate manual processes and reduce errors.
Mobile Applications
Cross-platform mobile apps with native performance. From consumer-facing products to internal field tools — built right the first time.
AI Business Integrations
Embed AI where it matters — document processing, intelligent routing, anomaly detection, and conversational interfaces wired into your existing workflows.
Business Intelligence
Dashboards and reporting pipelines that turn raw data into decisions. KPI tracking, automated reports, and executive-level visibility across your organization.
Data Science
From exploratory analysis to production ML pipelines. Statistical modeling, feature engineering, and data pipelines that deliver actionable insights at scale.
Custom Deep-Learning Modeling
Purpose-built neural architectures for your domain. Computer vision, NLP, time-series forecasting — trained, optimized, and deployed to production.
Proven in Production
Real systems handling real workloads. Every project below is deployed, tested, and built to last.
Energy Trading Platform

Energy Price Forecasting Engine
Custom neural network models for wholesale energy market price prediction — probabilistic forecasting with uncertainty quantification, topology-aware graph modeling of physical grid constraints, and automated trading signal generation.
Key Results
- Probabilistic price forecasting with confidence bands
- Graph-based physical grid topology modeling
- Automated signal generation and bid optimization
- Continuous retraining on live market data
We Eat Our Own Cooking
Grand Oak Software is the software arm of a real trading operation. We built our own energy trading platform, fund management portal, and secure communications system — not as portfolio pieces, but because we needed them to work.
That same rigor goes into every client project. We don't build throwaway prototypes — we build systems that handle real traffic, real money, and real deadlines.
Built by Builders
We're engineers who ship production systems, not slide decks. Our own trading platform handles real money — we build everything to that standard.
Competitive Rates
We deliver enterprise-grade software without enterprise-grade overhead. Efficient stacks and lean processes mean more value for your budget.
Full Stack, No Gaps
From database schema to deployment pipeline, we own the entire stack. One team, one vision, no finger-pointing between frontend and backend.
Battle-Tested Stacks
Rust for performance-critical systems. Next.js for modern web. We choose technology for reliability and maintainability — not hype cycles.
