Asher Kutswa

Software engineer with direct, hands-on experience auditing and evaluating SWE-Bench-style coding tasks for technical accuracy, solvability, and test reliability, combined with three years of professional software engineering experience across production backend systems and multiple languages (Python, C++, Go, PHP). Comfortable navigating unfamiliar codebases, identifying integration issues and logic errors, and providing clear, actionable technical feedback. First-Class Honours graduate (Business & Information Technology, Strathmore University) with a Master's-level exchange at KTH Royal Institute of Technology.

AI Training Data Contributor at AfterQuery (2026-01 – Present)

• Authored and audited code-based benchmark tasks across Python, Go, C++, and Shell/Bash, verifying that each task was technically accurate, realistic, solvable, and reproducible before submission.
• Directly applied Oracle/NOP validation methodology — confirming a correct reference solution passes and an empty/no-op attempt correctly fails — the same rigor standard used in SWE-Bench-style evaluation.
• Identified and resolved test failures, logic errors, and originality/duplication issues flagged during an 8-stage automated review pipeline (CI checks, an 11-criteria quality rubric, difficulty probing against frontier models), revising submissions until they met technical and evaluation-criteria standards.
• Evaluated candidate repositories for task-readiness, auditing test coverage and structural integrity against defined acceptance criteria across 10+ Python repositories.

Lead Software Engineer at Léron Ltd (2025-02 – 2026-04)

• Architected a production backend (Django, DRF, PostgreSQL) and three Flutter mobile applications, navigating and extending a growing, multi-component codebase independently.
• Designed and validated authentication, schema, and API systems, including reasoning through edge cases and failure modes as part of implementation.

Full-Stack Contributor at Site Sync (2022-04 – 2024-11)

• Worked across multiple codebases and stacks (Django/PostgreSQL, earlier PHP/SQL/Vue.js prototypes), including auditing and refactoring existing code for performance and maintainability.

Information Technology Intern at SANCOM Ltd (2025-01 – 2025-07)

• Administered and validated data integrity across 3 MS SQL databases exceeding 2,000 records, ensuring ACID compliance.
