Hi, I’m Adil 👋
Java and Spring systems for business-critical workflows. I focus on predictable APIs, data integrity, secure integrations and service modernization.
Clear interfaces. Thoughtful workflows.
Every interaction has a purpose.
Applications that make the engineering tangible. Clear business rules, explicit boundaries and tested recovery paths.
Built a Spring Boot service for inventory reservations and fulfillment transitions.
Built a Spring Boot service for inventory reservations and fulfillment transitions. Added request-key deduplication, expected-version checks and retryable outbox fixtures. Tested concurrent stock requests, repeated cancellation and relay failures with JUnit using local synthetic state.
Created a Spring Boot partner gateway with explicit local role checks, versioned contracts and runtime validation.
Created a Spring Boot partner gateway with explicit local role checks, versioned contracts and runtime validation. Added a rolling request limit, trace IDs and distinct fixture deadline and dependency errors. Verified permission, contract, timeout and rate-limit behavior with JUnit.
Implemented Spring Boot assessment workflows with deterministic scores, deadline checks and duplicate-submission protection.
Implemented Spring Boot assessment workflows with deterministic scores, deadline checks and duplicate-submission protection. Required instructor review for feedback and versioned publication. Tested unauthorized edits and stale approvals with JUnit using synthetic learner records.
Java and Spring systems for business-critical workflows. I focus on predictable APIs, data integrity, secure integrations and service modernization.
Service upgrades, explicit contracts and secure API boundaries.
Query plans, schema evolution and relational/document modeling.
Event processing, idempotency, caching and partner integration.
Integration checks, repeatable infrastructure and release safety.
From healthcare workflows to financial platforms and enterprise SaaS.
Java and Spring Boot service upgrades, JPA query optimization, PostgreSQL indexing and Redis caching.
GraphQL services, document databases and infrastructure automation alongside modern Java and Spring delivery.
Spring Boot loyalty APIs, batched reconciliation workflows and authenticated partner integrations with signed webhooks.
Messaging and database integrations with replay-safe financial workflows.
Spring MVC, Hibernate and MySQL applications for claim intake and denial tracking, with validated REST imports.
