I'm Sigit Irawan, a full-stack developer in Jakarta. I spent three years fixing banking compliance systems where one wrong reporting rule means a regulator penalty, and built my own products outside work hours.

ABOUT ME

I learned to write code before university, and enrolled after three years of work. Most of what I know came from systems already running in production that were not allowed to break, not from coursework.

  1. Application Support Engineer

    2023 – 2026

    PT Nawa Data Solution

    Anti-money-laundering compliance platform for major Indonesian banks. AML, goAML, Case Management, PEP and Sipendar modules, with regulatory reporting to PPATK.

    • Fixed transaction reporting logic on databases in the hundreds of millions of rows.
    • Traced duplicate records back to a join-key mismatch, then turned the finding into a formal unit test document.
    • Validated XSD schemas for suspicious transaction reporting.
    • Cleaned a log table of roughly 145 million rows using batched deletes.
    • Optimised SQL Server queries and SSIS ETL pipelines, and wrote sequence diagrams for a process parallelisation effort.

  2. Co-Founder & Technical Lead

    2025 – present

    kitqu

    An AI platform for Indonesian students writing their thesis, positioned as a workflow layer on top of general-purpose AI.

    • Designed a multi-provider AI router with per-request token telemetry.
    • Built cross-session revision memory and supervisor writing-style calibration.
    • Run self-hosted VPS infrastructure and a Telegram bot for distribution.

  3. BSc Informatics

    2026 – 2029

    Universitas Siber Muhammadiyah

    Entered formal education after three years of work.

CAPABILITIES

Four areas I handle end to end on my own.

  • Product Engineering

    I build and ship complete web applications on my own, from the database schema to the page a user sees.

    • Next.js
    • React
    • TypeScript
    • Laravel
    • Livewire
    • Tailwind
  • Data & Backend

    I read query plans to find why a query is slow, and repair tables in the hundreds of millions of rows without locking a system that is still serving traffic.

    • SQL Server
    • PostgreSQL
    • Supabase
    • Redis
    • SSIS
  • AI Integration

    I route requests across several model providers behind one interface, and measure token cost per request so pricing rests on numbers rather than guesses.

    • Multi-provider router
    • Prompt engineering
    • Token telemetry
  • Systems & Compliance

    I have worked on systems where a reporting error ends in a regulator penalty, so I write test documentation before I call anything finished.

    • AML / goAML
    • PPATK reporting
    • XSD validation
    • QA documentation
