Mohamed Ishaque S — Software Engineer

Backend-focused SDET-2 at Zeta, specializing in quality engineering for fintech systems involving payment APIs and large-scale financial file-processing pipelines. I currently own automation and validation for backend services and batch systems used in production, including UPI transaction workflows (RuPay Credit Card on UPI) and FileHub-based ingestion and reconciliation pipelines. My responsibility spans API-level correctness, transaction state validation, reconciliation accuracy, and record-level integrity for high-volume financial files. My work includes designing end-to-end automation covering: – test data modeling and file generation – SFTP-based ingestion workflows – output file deserialization into POJOs – record-by-record business rule validation – CI-driven regression execution via Jenkins These suites are part of daily release validation and have reduced regression execution time from hours to minutes while significantly lowering production defect leakage in payment and batch-processing flows. I actively participate in production on-call rotations and have supported SEV-1 and SEV-2 incidents by reproducing failures in QA environments, validating hotfixes, and hardening regression coverage to prevent recurrence. Technically, my focus is on building stable backend automation frameworks in Java using Rest Assured and TestNG, with strong emphasis on maintainability, deterministic validation, and CI/CD reliability — not superficial test coverage. Earlier in my career, I worked on AI chatbot automation platforms, which strengthened my foundation in API validation, distributed system behavior, and framework design. I am currently targeting Senior SDET / Backend Automation roles in product companies where quality engineering is treated as a system-level engineering responsibility.

Promoted

Jan 2026 – Present · 2 mos · Bengaluru, Karnataka, India · On-site

Promoted to SDET-2 to own backend automation architecture and release quality for critical fintech systems, including UPI payment workflows and large-scale financial file-processing pipelines.
Own automation architecture for multiple backend services and batch systems, covering API validation, transaction state correctness, reconciliation accuracy, and record-level data integrity.
Designed scalable API automation for complex payment flows (authorization, settlement, reversals, failure handling, reconciliation) across dependent microservices.
Lead quality engineering for FileHub-based batch pipelines, including:
input file validation & controlled data modeling
transformation & processing verification
summary / failure record validation via output file deserialization into POJOs
cross-system reconciliation checks
Refactored legacy suites to support parallel execution and environment isolation, reducing regression runtime from hours to minutes and significantly improving CI stability.
Integrated and maintained Jenkins pipelines used for daily regression and release validation, acting as quality owner for production deployments (risk assessment, regression planning, sign-off).
Actively participate in production on-call rotations; supported SEV-1 and SEV-2 incidents by reproducing failures in QA, validating hotfixes, and hardening regression coverage to prevent recurrence.
Mentor junior SDETs on backend test design, framework usage, debugging practices, and writing production-grade JIRA defect reports.
Partner with backend engineers during incident analysis using logs, metrics, and request traces (Kibana) to accelerate root-cause identification.

Software Development Engineer in Test I

Apr 2024 – Dec 2025 · 1 yr 8 mos · Bengaluru, Karnataka, India · On-site

Worked as part of the fintech platform QA team responsible for backend automation and validation of UPI payment systems and financial file-processing workflows used in production.
Built and maintained API automation frameworks using Java, Rest Assured, and TestNG to validate UPI transaction flows including RuPay Credit Card on UPI and Credit Line on UPI.
Automated complex transaction scenarios covering debit, credit, reversals, refunds, reconciliation, and failure handling across dependent backend services.
Designed end-to-end validation for high-volume payment workflows, ensuring correctness of transaction state transitions, settlement logic, and downstream system integrations.
Implemented file-processing automation for reconciliation and financial workflows, including test data preparation, file generation, SFTP-based ingestion, and backend result validation.
Integrated automation suites with Jenkins CI pipelines to enable repeatable regression execution and faster feedback during development cycles.
Collaborated closely with backend engineers and product managers to clarify requirements, validate edge cases, and identify high-risk scenarios early in the development lifecycle.
Consistently raised high-quality defects with clear reproduction steps and impact analysis, contributing to improved release stability and reduced rework.
Built strong backend testing foundations that later enabled ownership of file-processing automation and promotion to SDET-2.

Sep 2022 – Mar 2024 · 1 yr 6 mos

Worked on building and scaling a unified UI + API automation framework for an AI-based chatbot platform used across web and backend services.
Designed and developed a Java-based hybrid automation framework integrating Selenium (UI) and Rest Assured (API), enabling end-to-end validation across frontend and backend layers.
Automated 400+ test cases covering feature flows, regression scenarios, and service-level API validations, significantly reducing manual testing effort and release cycle time.
Built reusable components for request construction, response validation, test data management, and environment configuration to improve maintainability and execution stability.
Integrated automation suites with Jenkins CI pipelines using Maven, enabling scheduled and on-demand regression execution as part of the release workflow.
Performed API-level validation including payload verification, response schema checks, and database assertions using SQL for data correctness.
Collaborated closely with developers and product teams in an agile setup to clarify requirements, identify edge cases early, and improve defect turnaround time.
Established strong foundations in API testing, framework design, and CI-driven automation that later enabled transition into large-scale fintech backend systems at Zeta.
