Click one to discover my role and contributions.
I’m Anugrah Patra, a software engineer based in Bandung, Indonesia, with 7+ years of experience across technical support, web development, backend systems, and full-stack product delivery.
I build real-time products, financial integrations, and the systems behind everyday business. My work spans requirements, architecture, APIs, implementation, debugging, testing, and release preparation—not just writing a feature in isolation.
I also run Jajaneun Chili Oil and build Oren POS. Being both a developer and a business operator helps me connect software decisions with how people actually work.

Real-time messaging, Go services, client integrations, and connected mobile/web products.
Own backend delivery from requirements and technical planning through implementation, debugging, integration tests, and release preparation. Work across REST, gRPC, WebSocket, Kafka, OpenIM, PostgreSQL, and Redis.
Financial products, partner integrations, approval workflows, and enterprise invoicing.
Built and maintained PaperCard, Horizon Card, Pioneer Card, e-Meterai, Open API, and custom client capabilities. Worked with product, QA, and DevOps on release verification and production issue analysis.
Multi-module ERP, backend architecture, performance tuning, and technical guidance.
Translated operational requirements into APIs, services, and data models. Contributed to code reviews, documentation, query optimization, and junior-developer mentoring.
Web applications for small businesses and university projects, including kreatip.id.
Delivered responsive interfaces, content management, forms, authentication, and database-backed workflows. Managed domains, hosting, deployment, maintenance, and post-launch improvements.
Hands-on foundations in workplace systems, networking, and ERP support.
Maintained PCs, routers, printers, local networks, and ERP applications. Diagnosed incidents, performed upgrades, documented fixes, and supported everyday technical requests.
The map is a playful way to explore this portfolio. Each building represents a project, a professional contribution, or my own business. Here’s the same experience in reading mode.
This building represents my work on interactive web products and the services behind them. The local football demo below illustrates interaction states, input handling, and visual feedback.
Reliable interaction is about the full lifecycle, including what happens while an action is still in progress.
Implemented Go services and client integrations using REST, WebSocket, and Protobuf. Adapted API contracts to connect backend behavior with web and mobile experiences.
Worked through requirements, technical planning, debugging, integration checks, and deployment preparation.
A complete interaction loop: choose a target, lock inputs during the shot, resolve the keeper’s move, update the streak, and start a new round.
At Citra, I work on real-time messaging and connected services for mobile and web products. This station is about the backend communication, contracts, and delivery work behind a conversation—not only the chat interface.
The visible conversation is only one part of the product. Clear contracts and dependable service communication make it work.
Built and maintained integrations across OpenIM, WebSocket, REST, and gRPC, with Kafka supporting service communication and event handling.
Integrated Ethereum and Solana wallet flows covering wallet creation, transaction processing, smart-contract interaction, and service-to-service events.
Worked from requirements and API contracts to debugging, repeatable integration checks, regression validation, and production-readiness preparation.
At Paper.id, I contributed to PaperCard, Paper Horizon Card, Paper Pioneer Card, and supporting financial services. The work covered partner integration and the internal services that keep approvals and transaction data connected.
My contribution sits in the service and integration layer behind the product. The card shown here is an illustrative interface.
Integrated financial partners including BRI, CIMB, and Ayoconnect through service contracts and reusable external integrations.
Built and maintained card-product capabilities, Open API, workflow automation, and multi-step approval flows.
Improved REST contracts, database queries, failure handling, and cross-service consistency. Collaborated with QA, product, and DevOps on release verification and production issue analysis.
This coffee house represents custom invoicing and enterprise integration work for Kopi Kenangan during my time at Paper.id. The focus was adapting financial services to client-specific business workflows.
This is integration experience through Paper.id, rather than employment at Kopi Kenangan. The invoice below contains sample data.
Implemented custom invoicing and enterprise integration requirements alongside the existing Paper.id platform.
Worked on approval workflows, reusable external integrations, and clear service contracts between business systems.
Supported cross-service data consistency, release verification, and issue investigation around payment and invoicing reliability.
At Eigen Tri Mathema, I built and maintained backend services for large-scale, multi-module ERP applications. The work connected operational requirements with maintainable APIs, data models, and integrations.
ERP engineering means making connected workflows understandable and maintainable as the business grows.
Translated operational requirements into backend services and data models, with attention to consistency across ERP modules.
Contributed to solution architecture, REST API design, scalability, performance tuning, and database-query optimization.
Led code reviews and technical guidance, mentored junior developers, and worked with frontend, QA, and DevOps from implementation through release follow-up.
Oren POS grew from hands-on F&B operations. I build and maintain the platform while also working with the real sales, stock, and cashier processes it needs to support.
I get to see both sides: how the software is built and how it feels when someone depends on it at the counter.
Built sales, inventory, product management, stock movement, cashier workflows, and reporting capabilities.
Delivered applications using React, Next.js, and Flutter, with responsive dashboards and cross-platform cashier workflows.
Own product planning, deployment, maintenance, and ongoing improvements informed by daily business operations.
Jajaneun is my F&B venture and a part of my life beyond software. Running the business also gives me direct context for the product decisions behind Oren POS.
Building useful software starts with understanding the people and everyday work around it.
Work on the business itself, from product planning to ongoing operations and continuous improvement.
Use real operational feedback to understand what sales, inventory, and cashier workflows need from software.
