Software engineer at IBM. I help shape the solution with the team and clients, then design and build it. I also enjoy explaining code in simple terms.
Front-end feature work on several production Angular apps for airline and travel clients. Booking flows, deep linking, interactive maps, real-time status tracking, and a multilingual UI that switches language at runtime. State in NgRx/RxJS; data over GraphQL and REST via AWS Amplify.
A real-time decision-support hub for a US utilities company. It pulls operational KPIs from several systems into one screen operators can read at a glance during an incident.
A data platform for utilities. Teams get their own workspaces, build data flows on a drag-and-drop canvas, and follow them on live metrics dashboards. Grid models are converted to the CIM standard and processed on AWS with Lambda, Step Functions and Kafka, behind role-based access in Cognito.
A few examples of my work across application development, system design and AWS.
On IBM projects, I work across the feature from the existing data model and APIs to authorization and AWS resources, then write the design and work through it with the team.
For example: CSV rule import with column mapping, and a check of which rules a ruleset deletion would affect.
Worked on a multi-user platform where several people could edit the same configuration. I traced how changes flowed through the services and both storage layers (Postgres and S3), then designed and implemented an approach combining time-limited edit locks with version checks on save. A save made from an out-of-date copy is rejected with a conflict instead of silently overwriting someone else's newer changes.
Worked on role-based access control for a platform where a user's role can differ from one workspace to another. This covered the role model, invitations and role changes, and a Cognito pre-token trigger that adds each user's workspace roles to the access token, so every API request is checked against the role for the workspace it touches.
Worked with OAuth 2.0 and OpenID Connect, including the Authorization Code flow with PKCE using Cognito and Amplify. The API authenticates requests with Cognito, and the backend uses the verified identity to check permissions.
The stack behind most of my work at IBM.
Used on IBM projects alongside the core stack.
The cloud services the platforms I work on are built from.
From earlier work and side projects, with the code on GitHub.
At IBM I help run client demos. Outside of that, I simply enjoy explaining programming concepts in a simple way, and some of my posts on dev.to come from that.
A shop split into Spring Boot services for customers, inventory and billing, with Eureka for discovery, a Config Server for shared settings, and a Spring Cloud Gateway in front. Billing builds each invoice by calling the customer and inventory services through OpenFeign.
A Java service that sends a question to an LLM, stores the answer, and hands it back over a clean REST endpoint.
An expense tracker split in two: an Angular front end for entering and reviewing spending, and a JEE back end holding the accounts and totals.
