Selected Projects

Gravity

Gravity OS

A desktop application designed to run Large Language Models locally, powered by Ollama. It enables users to download, manage, and orchestrate multiple open-source models directly on their machine without relying on cloud APIs. The system acts as a lightweight AI operating layer — allowing structured agent collaboration, task execution, and model coordination in a controlled local environment.

Challenge

Developers needed a way to run AI models locally without cloud dependency or API costs.

Solution

Built a desktop OS layer with Electron and React, orchestrating local LLMs via Ollama with a Python backend.

Results

Enabled offline AI workflows, reducing API costs to zero while maintaining full data privacy.

AI Pharma E-commerce

AI-enabled e-commerce platform for a pharmaceutical company that automates medicine ordering, prescription validation, inventory control, and intelligent customer assistance. The system supports both B2C customers and B2B bulk buyers (clinics, distributors, hospitals) while ensuring regulatory compliance, data security, and operational efficiency.

Challenge

Pharma company needed a compliant, AI-powered platform to handle B2C and B2B orders with prescription validation.

Solution

Developed a Next.js frontend with Spring Boot backend, integrated OpenAI for intelligent assistance, and built compliance layers.

Results

Supported 10K+ daily users, automated prescription validation, and achieved regulatory compliance.

Core

Core Banking Integration

Event-driven integration layer between legacy core banking systems, FLEXCUBE SOAP APIs, and modern REST services.

Challenge

Legacy banking system needed to connect with modern discounts services while maintaining transaction integrity.

Solution

Built an event-driven integration layer using Spring Boot and Kafka to bridge FLEXCUBE SOAP APIs with REST services.

Results

Achieved 99.9% uptime, processed millions in daily transactions, and enabled real-time data sync.

FAQS

Common Questions

Frequently Asked Questions

I work in focused, high-velocity sprints: less complex features and MVPs are typically delivered within 2-3 days. For more complex, production-grade systems, the timeline extends to around 1 week based on scope and complexity. I provide detailed timelines after the discovery phase and stick to them.

Both. I can integrate with your existing engineering team or handle full project delivery independently. I'm comfortable working solo, augmenting your team, or leading development efforts.

I offer fixed-price projects for well-defined scopes and hourly billing for ongoing work. All engagements start with a discovery call to define scope, timeline, and budget.

Weekly demos, async updates via Slack/Teams, and monthly strategy calls. You'll always know the project status. I use project management tools for transparency.

Backend: Java Spring Boot, Node.js, Python. Frontend: Next.js, React, TypeScript. Cloud: AWS, Docker, Kubernetes. AI: OpenAI, Ollama, LLM orchestration. Databases: PostgreSQL, Redis, MySQL.
